Explore The Wonders Of Indonesia
Tual – Kaimana Beyond Forgotten Islands Exploration 14 Nights
From the Forgotten Islands to Triton Bay, into one of Indonesia’s last diving frontiers
Few journeys in Indonesia connect two underwater worlds as remote and distinctive as the Forgotten Islands and Triton Bay.
Beginning in the remote waters beyond Tual, our expedition takes us through isolated seamounts and coral reefs scattered across the eastern seas of Indonesia before continuing towards the wild coast of West Papua and the extraordinary marine ecosystems of Triton Bay.
The first part of the journey captures the true spirit of the Forgotten Islands. At Five Meter Patch, Ultima Frontera, Karang Huisman, Karang Rembrang and Little Manuk, pristine reefs rise from deep oceanic water, often many miles from the nearest inhabited island. Powerful currents bring nutrients to spectacular coral plateaus and walls, attracting schools of barracuda, giant trevallies, dogtooth tuna and reef sharks. Exceptional visibility and remarkably healthy coral make these remote offshore reefs some of the most exciting wide angle diving of the expedition.
As we continue east, the journey gradually changes character. After crossing the Arafura Sea we reach Momon Seamount, an isolated underwater mountain surrounded by deep water and known as a cleaning station for oceanic manta rays. Nearby, freshwater pours directly from the rainforest into the sea at the spectacular Momon waterfall, providing one of those rare places where the wilderness above and below water become part of the same experience.
From Momon we enter Triton Bay, tucked away along the remote southeastern coast of West Papua and surrounded by jungle, dramatic limestone formations and isolated islands such as Aiduma, Dramai and Namatota.
Underwater, the transformation is remarkable.
Dense gardens of brilliantly coloured soft corals replace the exposed oceanic reefs of the first part of the journey. Huge black coral bushes, sea fans and coral covered bommies shelter an extraordinary variety of marine life. Schools of fusiliers, sweetlips and snappers fill the reefs, while wobbegongs, giant trevallies, mobulas, pygmy seahorses, ghost pipefish and countless smaller creatures provide a constant contrast between wide angle spectacle and exceptional macro diving.
Triton Bay is also home to one of its most remarkable endemic animals, the walking shark, which we search for during our night diving around Aiduma. Oceanic mantas may appear around the outer reefs and seamounts, while the combination of nutrient rich water and extraordinary coral diversity creates some of the most colourful underwater landscapes anywhere in Indonesia.
Above water, the scenery is equally extraordinary. Jungle reaches almost to the sea, limestone islands rise from turquoise water, hidden beaches appear between the cliffs and ancient rock art provides a glimpse into the human history of this remote coastline.
From isolated oceanic seamounts and pristine Forgotten Islands reefs to the extraordinary biodiversity, soft coral gardens and jungle covered landscapes of Triton Bay, this expedition is a journey through two of Indonesia’s last great diving frontiers.
From remote oceanic reefs to the extraordinary underwater world of Triton Bay
The waters beyond Tual mark the beginning of one of the most remote sections of our journey.
Here, the final reaches of the Forgotten Islands are defined by isolation. Submerged seamounts rise from deep oceanic water, pristine coral walls disappear into the blue and strong currents bring both nutrients and marine life to reefs that see very few divers.
Sites such as Five Meter Patch, Ultima Frontera, Karang Huisman and Karang Rembrang combine spectacular coral cover with excellent visibility and encounters with reef sharks, giant trevallies, dogtooth tuna and large schools of barracuda. Around Little Manuk, volcanic slopes meet healthy coral reefs where sea snakes, turtles and countless reef fish complete our exploration of this remarkable region.
But this expedition does not end there.
Crossing towards West Papua brings us into an entirely different marine environment and one of Indonesia’s most extraordinary diving destinations: Triton Bay.
The biological importance of Triton Bay became internationally recognised following major scientific surveys of its marine ecosystems. Researchers documented extraordinary soft coral diversity, extensive black coral forests, healthy populations of reef predators and species previously unknown to science. The region is now protected within the Kaimana Marine Protected Area.
For divers, this biodiversity translates into an extraordinary variety of underwater experiences.
There are coral covered seamounts, walls, pinnacles and enormous boulders. There are shallow coral gardens and current swept channels filled with schooling fish. There are sheltered sand and rubble areas where the focus changes completely to pygmy seahorses, nudibranchs, ghost pipefish and other small and cryptic species.
And there are reefs where soft corals and black coral bushes grow in extraordinary abundance, creating the intense colour for which Triton Bay has become famous.
At Momon Seamount, oceanic manta rays regularly visit the shallow plateau. Around Aiduma and Dramai, wobbegongs hide among coral covered rocks while fusiliers, sweetlips, snappers and trevallies move above the reef. At sites such as Larry’s Dive Heaven, Frantic Jack, Little Komodo and Pintu Arus, currents bring extraordinary concentrations of fish and pelagic activity.
The smaller inhabitants are equally important. Triton Bay is particularly rewarding for photographers and macro enthusiasts, with flasher wrasses, pygmy seahorses, ornate ghost pipefish and countless nudibranchs hidden among its reefs. At night, we have the possibility of encountering the extraordinary Triton Bay walking shark, an endemic species found in this region.
Triton Bay’s nutrient rich waters do not always provide the crystal clear visibility associated with more oceanic destinations. But those same nutrients sustain an exceptional concentration of coral and marine life. Here, the reward is not simply visibility. It is colour, abundance and biodiversity.
This contrast is precisely what makes the journey so special.
We begin among the clear oceanic waters and isolated reefs of the Forgotten Islands and finish surrounded by the extraordinary colour, biodiversity and wild landscapes of Triton Bay. Two very different underwater environments, connected in one remarkable expedition across Eastern Indonesia.
Come join us on this rare voyage, journeying from Tual through remote oceanic seamounts and pristine reefs, before crossing into the extraordinary biodiversity, vibrant coral gardens and wild landscapes of Triton Bay, all the way to Kaimana.
Tentative Itinerary
The itinerary may be adjusted at the discretion of the captain and cruise director based on weather conditions, which can sometimes be unpredictable, as well as the group’s overall experience. The goal is to offer the best possible diving and snorkeling sites according to the group’s interests and skill levels.
Day 1 - TUAL
Our expedition begins in Tual, gateway to the Kei Islands and the starting point for an extraordinary journey that will take us from the remote reefs beyond the Forgotten Islands all the way to Triton Bay and Kaimana.
After arriving in Tual, we transfer to The Seven Seas, settle into our cabins and begin setting up our dive equipment. After refreshments and lunch, we have our general trip and safety briefing while the vessel begins navigating away from Tual.
Depending on arrival times and conditions, we plan an easy check dive in the area, giving everyone the opportunity to become familiar with their equipment and get comfortable in the water before we begin exploring the more remote offshore reefs ahead.
As we leave the Kei Islands behind, The Seven Seas sets course towards Tayandu, and the real expedition begins.
Ahead of us lies a remarkable succession of isolated seamounts and reefs rising from deep oceanic water, places visited by very few boats and where healthy coral, clear water, schooling fish and pelagic marine life define the diving.
Day 2 - ULTIMA FRONTERA AND TAYANDU ISLANDS
TWe reach Ultima Frontera, one of the most remote dive sites of the expedition and a place whose name perfectly captures the atmosphere of this part of the journey.
The combination of outstanding visibility, pristine coral cover and powerful oceanic currents creates ideal conditions for both healthy reef growth and larger marine life.
Reef sharks move along the reef while dogtooth tuna and giant trevallies patrol the blue. Impressive schools of barracuda may gather around the site, creating spectacular opportunities for wide angle photography.
The current can add energy to the dives, but it is precisely this movement of water that brings nutrients to the reef and supports the abundance of marine life found here.
After our dives at Ultima Frontera, we begin navigating towards the Tayandu Islands.
The environment gradually changes as we approach the island group. After the exposed oceanic reefs and stronger currents of Ultima Frontera, the waters around Tayandu become noticeably calmer and more protected.
Depending on conditions and timing, we may visit a spectacular white sand spit sheltered inside the lagoon of a traditional pearl farm.
After a day dominated by current, pelagic fish and open ocean diving, the turquoise lagoon and white sand provide a beautiful contrast and another perspective on this rarely visited region of Indonesia.
Day 3 - KARANG HUISMAN, KARANG REMBRANG AND TAYANDU ISLANDS
Today we combine two exceptional offshore reefs, Karang Huisman and Karang Rembrang, both characterized by pristine coral, clear water and the possibility of larger marine encounters.
At Karang Huisman, dramatic vertical walls descend into clear blue water.
The walls are covered in flourishing coral growth and surrounded by large schools of fusiliers and trevallies, while reef sharks patrol the deeper sections and edges of the reef.
Excellent visibility allows us to appreciate the scale of the underwater landscape and makes Karang Huisman another particularly rewarding site for wide angle photography.
We then continue to Karang Rembrang, a remote seamount where the coral remains in superb condition.
Here again, the combination of deep surrounding water and oceanic currents attracts larger marine life. Reef sharks, trevallies, dogtooth tuna and schooling barracuda may all be encountered around the seamount.
The contrast between the colourful coral reef and the pelagic activity in the surrounding blue captures exactly what makes this part of the expedition so special.
After diving, we continue our navigation through the Tayandu Islands, where conditions become calmer as we approach the protected waters of the island group.
Depending on timing, we may once again have the opportunity to enjoy one of the beautiful white sand areas protected within the lagoon before continuing our journey.
Day 4 - LITTLE MANUK
Our final dives in this section of the journey take place around Little Manuk, where volcanic geology and healthy coral reefs come together.
Beneath the surface, volcanic slopes descend into clear water and provide the foundation for thriving coral ecosystems.
Reef sharks, sea snakes and turtles are among the larger inhabitants we may encounter, while countless reef fish bring movement and colour to the coral.
The presence of sea snakes is particularly characteristic of this broader region of the Banda Sea and Forgotten Islands, where volcanic islands and deep surrounding waters create a very distinctive marine ecosystem.
Little Manuk provides a fitting conclusion to the first chapter of our expedition.
But instead of returning towards Tual, our journey now takes an entirely different direction.
The Seven Seas begins the longer crossing towards West Papua, leaving these isolated oceanic reefs behind as we head towards the Arafura Sea, Momon and ultimately Triton Bay.
The transition is an important part of the expedition itself. The exposed seamounts and clear oceanic reefs of the first days will gradually give way to the nutrient rich waters, extraordinary soft coral growth and jungle covered landscapes that characterize the second half of our journey.
Day 5 - MOMON SEAMOUNT AND WATERFALL
After our night crossing, we arrive at Momon Seamount, an isolated underwater mountain rising from the depths of the Arafura Sea.
The top of the seamount reaches approximately 8 to 10 metres below the surface, creating a broad plateau surrounded by deeper slopes descending into open water.
Healthy hard coral formations cover the reef together with large sponges and sea fans, all benefiting from the nutrient rich water moving across the seamount.
Momon is particularly well known as a cleaning station for oceanic manta rays. The mantas are frequently observed gliding above the plateau, providing the possibility of one of the most memorable encounters of the expedition.
They are not the only larger animals found here. Bigeye trevally, batfish, Napoleon wrasse and giant trevally may also be encountered around the reef and in the surrounding blue.
Currents can vary considerably according to the tide, ranging from mild to strong. This water movement contributes to the health of the coral and the pelagic activity for which Momon is known.
We plan two dives at the seamount before heading towards a completely different natural attraction nearby.
Hidden along the jungle coastline is Momon Waterfall, where freshwater flows directly from the rainforest into the sea.
We approach by tender and have the opportunity to swim beneath the waterfall, enjoy a freshwater rinse after diving or simply take in the remarkable surroundings.
The contrast between cool freshwater, warm tropical sea and dense rainforest makes this one of the most unusual and memorable surface experiences of the expedition.
Day 6 - PULAU AIDUMA, TRITON BAY
The day begins under soft morning light, the sea a perfect mirror reflecting the jungle-clad hills of Triton Bay. The air is still cool as the crew gears up, three dives ahead, each promising a different face of this underwater paradise.
True to its name, Aquarium feels like diving into a natural fish tank. Gentle currents, and an explosion of color wherever you look. This site showcases Triton Bay’s coral diversity at its best, with fields of soft corals, hard coral bommies, and sponges shaped like sculptures. Anthias, butterflyfish, and angelfish dance through the light, while turtles glide serenely above the reef. Ideal for both beginners and photographers, Aquarium is a calm, immersive dive that reveals the gentler, more poetic side of this marine paradise.
Andy’s Point greets us with moving water and a touch of adrenaline. The current sweeps along steep coral-covered ridges, carrying clouds of fusiliers, barracudas, and trevallies. Massive black coral bushes sway in the flow, and every crevice hides life — wobbegongs resting motionless, pygmy seahorses clinging to gorgonians, nudibranchs glowing like jewels. This is Triton Bay at its wildest: raw, unpredictable, and absolutely thrilling. Each drift reveals a new surprise, each pause a tiny world waiting to be discovered.
As the afternoon sun softens, we descend on White Rock, a gleaming limestone pinnacle rising from the sea. Below the surface, the reef glows in the fading light, a masterpiece of coral and color. Flasher wrasses dance in bursts of neon, while ghost pipefish hover delicately between sea fans. Pelagic visitors sometimes glide past, mobulas, tunas, or sleek reef sharks, reminders that even in stillness, the ocean is never truly quiet. It’s a serene, almost poetic finale to a day of contrasts, from calm to current, from frenzy to peace.
Day 7 - PINTU ARUS - TRITON BAY AREA
Dawn breaks softly over Triton Bay, painting the water in hues of silver and gold. The sea is calm, the air charged with quiet anticipation — today’s dives promise both power and grace, a journey through the living pulse of the currents.
We begin the day at Pintu Arus, a site that lives up to its name, the “Gate of Currents.” Here, two water masses collide, stirring up a rich blend of nutrients that fuels an explosion of life. The current carries us through a corridor of color: soft corals and sea fans swaying like underwater gardens, tiny crustaceans tucked among branches, reef fish flashing past in every direction. Trevallies and jacks cut through the blue in sharp, synchronized bursts. It’s an exhilarating drift, the kind that makes you surrender to the rhythm of the ocean.
A short ride from Pintu Arus brings us to Little Komodo, one of Triton Bay’s most iconic sites. Named after its wild namesake in Komodo, it captures the same untamed spirit, a place where everything moves, glows, and breathes in unison. Descending into the blue, you’re greeted by a riot of color: orange and purple soft corals, swirling anthias and fusiliers, sweetlips hovering motionless above the reef. Along the edges, trevallies and mackerel hunt in formation, while wobbegong sharks rest camouflaged on the sandy bottom. When the current runs just right, the dive becomes pure poetry, a flowing ride through a storm of life and color that defines Triton Bay’s raw beauty.
As the sun lowers toward the horizon, we return to Pintu Arus to dive it from the other side. for a final dive. The light has softened, and the reef feels transformed. Shadows stretch across the coral, and schools of fish move in lazy synchrony, as if winding down for the day. The current, still present but gentler now, carries us in a calm, meditative drift, a perfect ending to a day defined by motion and light.
Back on the boat, golden reflections ripple across the bay. The crew is quiet, content, watching the last rays disappear behind the headlands. Three dives, one ocean, and a day that captures the untamed heartbeat of Triton Bay.
Day 8 - TELUK BITSYARI - KAIMAMA AREA
We’ll spend the morning diving and snorkeling beneath the bagans, traditional Indonesian wooden fishing platformsanchored offshore. Bagans lower large nets at night to catch baitfish (anchovies and sardines). At first light, the crew hauls the nets and rinses fish scraps over the water, this creates a natural feeding station that often attracts whale sharks, the “gentle giants” of Triton Bay.
We approach quietly by tender and enter the water in small groups to keep the scene calm. You’ll float beside the platform and let the sharks come to you, no chasing, no touching, always giving way. Visibility can be milky from plankton (that’s why the sharks are here!), but the close, unhurried encounters are unforgettable. Photographers should bring wide-angle setups; snorkelers enjoy eye-level moments as the sharks glide up from the blue.
After a full morning with these gentle giants, we’ll return to Namatota for a final dive in the area, an easy, scenic immersion along coral-draped slopes and boulder gardens
Day 9 - PULAU AIDUMA - TRITON BAY AREA
A new day begins as the vessel returns to the Triton Bay area. Today’s dives will take place around Aiduma Island, one of the region’s best-known diving zones. The island’s coastline features a mix of steep rocky walls, coral slopes, and sheltered bays that host an exceptional variety of marine life.
Three daytime dives are planned around the island, each highlighting a different aspect of Aiduma’s underwater landscape, from vibrant coral gardens and macro-rich reefs to dramatic rock formations. The day will end with a night dive near the resort, offering a chance to search for one of Triton Bay’s most remarkable endemic species.
Bo’s Rainbow is one of Triton Bay’s most colorful and photogenic reefs. The site features a shallow profile, with depths averaging around 12–18 meters, making it suitable for both macro and wide-angle photography. Large coral bommies are covered in black coral bushes and soft coral gardens that attract a wide variety of reef life. Divers may encounter pygmy seahorses, nudibranchs, pipefish, and hawk groupers among the corals. The site also includes a small shallow swim-through that cuts through part of the island, adding variety to the dive. With mild conditions and rich coral growth, Bo’s Rainbow showcases the healthy, vibrant reef ecosystems typical of Triton Bay.
Named after the Indonesian term for “Falling Rock,” Batu Jatuh is characterized by large boulders that slope into deeper water, forming a terrain of canyons, ledges, and crevices. The rocks are densely covered with soft corals, sponges, and sea fans, creating a colorful and textured environment. Marine life commonly observed includes schools of snapper, moray eels, octopuses, and a variety of reef fish species. On clear days, sunlight filters through the formations, illuminating the coral walls and giving the site excellent photographic appeal. Batu Jatuh offers both scenic topography and rich marine biodiversity, suitable for slow exploration and observation.
Tangga is a versatile dive site combining sea fans, sandy areas, and scattered coral bommies. The variety of habitats supports an abundance of small marine life, making it a preferred site for macro enthusiasts. Typical sightings include pygmy seahorse, ornate ghost pipefish, and numerous species of nudibranchs. The site generally features gentle currents and good visibility, allowing for relaxed, detailed diving. With its mix of coral structures and open patches, Tanga provides an excellent opportunity to observe Triton Bay’s characteristic diversity in a compact, easily navigable setting.
The day concludes with a night dive in front of the resort at Aiduma Bay, a shallow area of sand and coral rubble ideal for observing nocturnal marine life. This site is known as a potential location to encounter the Triton Bay Walking Shark (Hemiscyllium sp.), an endemic species found only in this region. During the dive, divers may also observe crustaceans, cephalopods, benthic fish, and a range of invertebrates that become active after dark. The calm conditions and moderate depth make this an accessible and rewarding site for night exploration.
Day 10 -PULAU DRAMAI & PULAU AIDUMA - TRITON BAY AREA
A new day begins as we continue exploring the outer islands of Triton Bay, an area known for its rich coral ecosystems and dramatic underwater scenery. Today’s dives focus on the region’s western side, visiting Dramai, Batu Jeruk, and Christmas Rock, three sites that highlight the diversity of habitats and marine life found in this part of the bay.
Named after one of Triton Bay’s outer island, Dramai offers a mix of shallow coral gardens and steep slopes covered in soft corals. The site is often the first dive of the day, with excellent morning light illuminating the reef. Orange and pink soft corals dominate the upper sections, while deeper areas feature gorgonians and sponges that attract a wide range of reef fish. Common sightings include fusiliers, sweetlips, wobbegongs, honeycomb more eels, and during periods of stronger current, blue fin and giant trevallies may pass through the area. The combination of vibrant coral cover and pelagic activity makes Dramai a representative dive site for Triton Bay’s outer reef systems — colorful, healthy, and full of movement.
Meaning “Orange Rock” in Indonesian, Batu Jeruk is named for its bright orange and gold soft corals that dominate the landscape. The site features large coral formations and bommies surrounded by sandy patches and scattered sea fans. Typical marine life includes glassfish, trevallies, and barracudas in the open water, while closer to the reef, divers may find shrimp, pipefish, and ornate ghost pipefish hidden among the coral. The vivid coral colors are especially striking in sunlight, giving Batu Jeruk a warm, glowing appearance that makes it one of the most visually distinctive reefs in the area.
Christmas Rock is a colorful and lively reef system characterized by large coral bommies and dense schools of reef fish. Sweetlips, surgeonfish, and yellow snapper are commonly found here, often gathered around the coral heads in large numbers. The steady current brings nutrient-rich water that supports the reef’s health and color. Divers may also encounter rays resting on the sand, and a wide variety of nudibranchs. With its strong coral growth, high fish density, and bright natural light, Christmas Rock captures the abundance and vibrancy that define diving in Triton Bay.
These three sites — Dramai, Batu Jeruk, and Christmas Rock — offer an excellent overview of the outer reef environments of Triton Bay. From steep coral slopes and pelagic visitors to dense reef fish populations and colorful soft corals, each dive showcases a different facet of this remote and biologically rich region
Day 11 - PULAU DRAMAI & PULAU IRIANJAYA - TRITON BAY AREA
Today’s dives include Tanjung Nambimia, the opposite side of Dramai Island, and Wet Dream, three sites that combine strong currents, coral-rich formations, and excellent fish activity. Together, they showcase the powerful and dynamic underwater environments typical of this region.
Located at a prominent headland, Tanjung Nambimia is a drift dive known for its strong currents and impressive underwater landscape. The site is made up of a series of large boulders and ridges covered in both soft and hard corals, forming natural channels that funnel water movement and attract marine life. Divers are often surrounded by large schools of fusiliers, jacks, and giant trevallies moving through the current. Napoleon wrasse are occasionally seen cruising along the reef, while pelagic species may pass through the open blue, drawn by the rich flow of nutrients. The combination of structure, current, and active fish life makes Tanjung Nambimia an exciting and energetic first dive of the day, ideal for experienced divers comfortable with drift conditions.
The opposite side of Dramai Island offers a different exposure to current and a contrasting topography from the main reef explored previously. The area consists of sloping coral ridges and walls decorated with sponges, gorgonians, and dense soft coral growth. Marine life includes sweetlips, batfish, surgeonfish, jacks, giant trevallies and fusiliers, along with occasional wobbiegongs. Depending on current direction, this site can alternate between calm observation and steady drift, offering a balanced and varied dive experience.
Situated off the coast of Dramai Island, Wet Dream is among Triton Bay’s most spectacular and densely populated dive sites. The underwater terrain consists of a chain of submerged ridges separated by sandy channels that extend outward toward open water. The ridges are covered in vibrant soft corals, sponges, and sea fans, and are surrounded by exceptional fish activity. Large schools of fusiliers, trevallies, and groupers are commonly observed, while honeycomb moray eels often inhabit crevices and overhangs. With strong currents and high nutrient flow, Wet Dream offers intense color, movement, and biodiversity — a true highlight of Triton Bay diving.
After the final dive, the vessel anchors near La Playa, a small sandy beach where the day ends with snacks and drinks at sunset. Divers and crew gather to relax, share impressions of the day, and enjoy the view as the light fades over the bay.
It’s a calm and fitting close to a day defined by movement, color, and the unmistakable energy of Triton Bay’s southern reefs.
Day 12 - PULAU AIDUMA - TRITON BAY AREA
Today’s dives take place in the Iris Strait, an area exposed to open ocean flow and known for its striking underwater topography. The sites here combine large rock formations, channel systems, and sheltered coral gardens, offering a balance of scenic wide-angle terrain and delicate macro environments.
The plan includes two morning dives at Boulders and 3 Rocks, followed by an afternoon dive at Flasher Beach, one of Triton Bay’s most renowned macro sites. Together, these dives showcase the diversity of habitats and marine life that define the region’s eastern passages.
As its name suggests, Boulders consists of massive rock formations scattered across the seabed, covered with gorgonians, sponges, and soft corals. The rocks form natural swim-throughs, overhangs, and caverns that create both scenic and habitat complexity. Common marine life includes lionfish, moray eels, and pufferfish sheltering in crevices. Shrimp, crabs, and other invertebrates can often be found among the rubble and coral bases. When sunlight filters through the gaps, the site takes on a dramatic atmosphere, a play of light and color that makes Boulders one of the most visually engaging sites in the Iris Strait.
3 Rocks, located in the heart of the Iris Strait, consists of three prominent pinnacles that form a natural mini-pass. This structure channels water, nutrients, and fish life between the rocks, creating a dynamic environment ideal for drift-style diving. The dive begins over soft coral slopes (5–18 m / 15–60 ft) and continues between the pinnacles, where sea fans and whip corals line the walls. The current here can range from mild to strong, making each dive slightly different depending on the tide. Marine life typically includes clouds of anthias and fusiliers, snappers around the bommies, and during stronger flow, jacks or trevallies sweeping through the pass. In calmer areas, divers can focus on smaller species such as nudibranchs, crustaceans, and tiny perching fish among the fans.
Also known as Secret Beach, Flasher Beach is one of Triton Bay’s signature macro dive sites, located along a sheltered cove not far away form the dive resort. The dive features shallow coral gardens and sand-and-rubble patches, perfect for spotting small, cryptic species. Typical finds include nudibranchs, pygmy seahorses, shrimp, and other reef invertebrates. The site is most famous for its flasher wrasses, which perform their vibrant mating displays in the late afternoon, flashing brilliant blues and reds as they court above the coral. With gentle conditions, good visibility, and consistent subject diversity, Flasher Beach is ideal for macro and behavior photography, offering an intimate look at Triton Bay’s smaller marine life.
After surfacing from the final dive, the vessel anchors in a calm bay for snacks and drinks at sunset. The day’s sequence — from the rugged formations of Boulders and 3 Rocks to the intricate details of Flasher Beach, captures the full spectrum of what Triton Bay offers: powerful structure, rich flow, and delicate life.
Day 13 - PULAU AIDUMA - TRITON BAY AREA
Our final full day of diving takes us back to three of Triton Bay’s highlights — Little Komodo, Pintu Arus, and The Aquarium — a perfect way to revisit the sites that best capture the region’s diversity and energy.
Each dive offers a different rhythm: the vibrant coral gardens and swirling fish of Little Komodo, the dynamic currents of Pintu Arus, and the calm, colorful reefs of The Aquarium. Together, they form a complete portrait of Triton Bay’s underwater world — wild, rich, and full of life.
As the sun sets, we gather on deck with snacks and drinks, reflecting on the week’s dives and the unforgettable beauty of this remote corner of Indonesia, a fitting end to our journey beneath the waves.
Day 14 - NAMATOTA ISLAND AND KAIMANA AREA
With our diving completed, today gives us the opportunity to experience Triton Bay above the surface before beginning our final journey towards Kaimana.
The same limestone formations that created the underwater scenery of Open Sky rise dramatically from the sea, covered in dense tropical vegetation and forming a spectacular coastline of cliffs, bays and hidden corners.
We can explore this landscape by kayak, moving quietly along the limestone coastline and experiencing the remarkable meeting point between rainforest and sea.
Later, we take the speedboat to discover another side of the region: its ancient rock art.
These paintings provide a fascinating connection with the people who inhabited and travelled through this coastline long before modern visitors arrived, adding a cultural dimension to a journey that until now has been dominated by the natural world.
We can then stop at a remote beach for drinks and snacks, enjoying our final afternoon surrounded by the wild scenery of West Papua.
As the light begins to soften, we return to The Seven Seas and set sail towards Kaimana.
It is a deliberately relaxed final day after almost two weeks of exploration, giving us time to appreciate the extraordinary landscape through which we have travelled before our last night aboard.
Day 15 - KAIMANA
After breakfast, our 14 night expedition from Tual to Kaimana comes to an end.
We disembark The Seven Seas in Kaimana and transfer to the airport for onward flights.
