Bo's Rainbow
Also known as Batu Sugih or Andie Reef, Bo's Rainbow is a sheltered island dive site in Triton Bay that suits divers looking for a relaxed profile without compromising on marine life. The site is typically calm, and in weaker current conditions it is possible to circumnavigate the entire small rock. The reef is draped in near-endless soft coral gardens that draw in large schools of fish. Fusiliers and sweetlips are common here, often appearing in the deeper or more saturated colour variations that distinguish Triton Bay's populations from those elsewhere. The site is also known for its macro life: nudibranchs, rare decorator crabs, and sea slugs are found among the corals, alongside the occasional giant bumphead parrotfish. Ghost pipefish and blade shrimp have been recorded in the black coral bushes, and the shallows feature a passage where wobbegong sharks are often seen resting during the day.
Average depth sits around 16 metres, with a maximum of roughly 25 metres. Visibility at Bo's Rainbow is typically in the 5 to 10 metre range, a common characteristic of Triton Bay dive sites owing to nutrient-rich water. The site's sheltered position means current is usually mild, though some flow can be expected at certain times. For underwater photographers, the density of soft corals and schooling fish makes wide-angle lenses a natural choice, while the resident macro subjects reward a closer approach.
Disney Land
With a name like Disney Land, it is no surprise that this site was named by the legendary American diver Larry Smith. From the surface the site appears to be a small island of rock breaking through the surface in the Iris Strait, between Aiduma and Dramai islands. Below the waves is a series of sloping reefs, many of which are covered by masses of black coral as far as the eye can see. There are often a lot of sweetlips and snapper on the site. In the sometimes strong current they are most often found nestling in sheltered spots close to the reef and among the corals. This is a relatively shallow Triton Bay dive site as most of the fun takes place in less than 18 metres of depth.
One creature of particular interest here is the wobbegong shark. This unmistakeable bottom-dwelling, carpet shark can be seen lying with its flat body against the sand with its frilly whisker tassles protruding from around its mouth. They are very well camouflaged so keep your eyes peeled otherwise you might just swim over the top of one and miss it.
GT Rock
One of the reasons why divers love Triton Bay is that at some sites, when the conditions are just right, the volumes of fish can be extraordinary. Unusual therefore that GT Rock should take its name from a single species - the giant trevally. When the current is flowing this can be one of those dive sites with a lot of action going on including the eponymous giant trevallies, tuna, fusiliers darting around in the blue. You might be out there too, being pushed along by the sometimes very strong current.
Closer to the reef will lurk large numbers of grunts, sweetlips and red snapper sheltering from the current. If you need a breather then it is always wise to drop in on the leeside of some pinnacle or jutting part of the wall to relax for a while. In the absence of the current there may not be such heart-stopping action, but it is worth investigating the reef for some of the smaller creatures such as scorpionfish, hawkfish and pygmy seahorses. Also keep an eye on the sandy bed for wobbegongs and rays. T Rock showcases the thrilling side of diving in Triton Bay.
Larry's Heaven
Situated right next to Little Komodo, Larry's Heaven is the signature dive site of Triton Bay, a name that carries weight among divers who have followed the exploration of this remote region. It was named in honour of Larry Smith, the American diver and pioneer who first documented and named many of Triton Bay's dive sites before his death. For those who knew of his work, diving here carries a sense of pilgrimage. The topography is a combination of sloping reef and vertical wall. The reef starts shallow, around 5 metres, and drops to over 40 metres on the deepest edge. The photogenic soft coral coverage is concentrated in the 8 to 20 metre band, where the reef is draped in dense formations of black coral trees, sea fans, and colourful soft corals. Marine survey teams who first documented Triton Bay in 2006 noted that the soft-coral density here exceeded their Raja Ampat reference sites, which is a significant claim given the region's reputation.
The fish life is the other draw. Schools of bigeye trevally can be thick enough to darken the water overhead, particularly during the strongest current weeks. Fusiliers and snapper are present in large numbers, and dogtooth tuna patrol the deeper edges of the reef. Sweetlips and anthias decorate the reef with their colours, and the site is often described as the most popular dive in Triton Bay for good reason. The sandy slope on the south-west side is worth checking for flasher wrasse and sand divers, small fish that are easily overlooked by scuba divers focused on the larger action.
Currents at Larry's Heaven are generally minimal to moderate, which makes the site accessible to intermediate divers. Visibility can range from 10 to 30 metres depending on conditions, and on a good day the water is clear enough to appreciate the full scale of the soft coral gardens. The site is sometimes called The Aquarium, a name that reflects the sheer density of marine life rather than any particular topographical feature. For photographers, the combination of wide-angle soft coral scenes and the chance to capture schooling fish against the light makes Larry's Heaven one of the most productive dives in the Triton Bay region.
Little Komodo
Saruenus Island's Little Komodo earns its name from the resemblance its underwater topography bears to the reefs of Komodo National Park, though the site has a character all its own. The dive is structured around a series of large granite boulders and coral-crusted ridges, with a channel that cuts through the reef and a vertical stretch that drops along the island's edge. When the current is running, this is a site that rewards a degree of concentration: the reward is a reef so densely packed with life that visibility can feel secondary to the sheer volume of fish.
The soft coral coverage here is the headline attraction. Fields of pastel-hued soft corals, black corals, and oversized gorgonian fans drape the boulders and walls, creating a landscape that shifts between sheltered gullies and current-swept corners. Schools of fusiliers, rainbow runners, and snappers move through the water in tight formations, and bumphead parrotfish are often seen grazing on the reef or hanging in the current at the channel's end. Pygmy seahorses have been recorded clinging to the sea fans at depths shallower than is typical for the species, sometimes as shallow as 15 metres. Nudibranchs of various species are also present for those who slow down and scan the coral surfaces.
For photographers, Little Komodo offers a mix of wide-angle opportunities and macro subjects. The combination of soft coral gardens, schooling fish, and the chance to shoot upwards through the water column toward the surface makes it a productive site for natural-light images. It is one of the signature dives of any Triton Bay tour and a reliable indicator of why this region has earned its reputation as a biodiversity hotspot. The site is rated as suitable for intermediate divers. Currents can be moderate to strong, and the wall section may be inaccessible when downcurrents are running. The dive is typically conducted as a drift, with divers dropping on the vertical stretch and moving around the corner into the channel before ascending in the shallows. Maximum depth is around 25 metres, though most of the notable life is found between 10 and 20 metres.
Namatota
Less a conventional reef dive and more of a cultural and wildlife experience, Namatota has become one of the signature attractions of Triton Bay diving. Traditional Papuan fishermen operate bagans near Namatota Island, bamboo fishing platforms extending from boats. Each night, the fishermen drop nets to catch ikan puri, small anchovy-like baitfish. When the nets are hauled in each morning, whale sharks often follow, drawn by the scent and the easy meal. For divers and snorkellers, this creates a rare opportunity to enter the water alongside whale sharks in shallow, calm conditions.
The sharks, which can measure 5 to 6 metres or more, are accustomed to the presence of boats and fishermen, and encounters are typically unhurried. The fishermen share a portion of their catch with the sharks, and dive operators pay a stipend to the bagan crews for access, a system that benefits both the local community and the visiting scuba divers. Scientists have also established monitoring and tagging programs at these platforms to study the visiting whale sharks. The encounter is most reliable from December to February, when multiple individuals may be present at the platforms. Outside this window, whale shark sightings are less predictable, though the bay still offers excellent diving at other nearby sites. Visibility at the bagans is typically in the 10 to 15 metre range.
Above the waterline, the limestone cliffs of Namatota Island are painted with ancient rock art. The ochre paintings depict fish, turtles, lizards, and human figures, estimated to be thousands of years old, created by the ancestors of the local Kaimana communities. Most liveaboard cruises stop at Namatota specifically to combine the whale shark encounter with a viewing of the rock art, making it a unique pairing of natural and cultural heritage. The whale shark experience at Namatota is accessible to snorkellers and divers of all levels, as the encounters take place in shallow water and the sharks are generally calm and slow-moving. It is a highlight of any Triton Bay diving trip, though the diving itself is focused on the surface interaction rather than a reef profile.
Orange Rock
Also known as Batu Jeruk, this site in the east of Aiduma Island takes its name from the vibrant orange soft corals that encrust its slopes. The reef here features a series of ridges and gullies that provide shelter from the current, making it a comfortable Triton Bay dive even when conditions are livelier elsewhere. Look for schools of anthias hovering above the coral, and keep an eye out for passing mackerel and trevally in the blue. The shallower sections are excellent for spotting nudibranchs and other macro subjects.
