Triton Bay

Alongside Raja Ampat and Cenderawasih Bay, Triton Bay formed the Bird’s Head Seascape in the West Papua region. In 2008, the waters around Kaimana and Triton Bay were declared a Marine Protected Area, covering 6000 square kilometers, ensuring the biodiversity of the marine life thrives and evolves.

Sharing the same DNA as Raja Ampat, Triton Bay boasts more than 900 species of reef fish, over 400 species of coral, some extraordinary endemic creatures, and sharks. Based on this data alone, Triton Bay should be high on the list of dream destinations for avid divers.

Exploring many of the dive sites in Triton Bay taps into one of the magnificent underwater environments in the Coral Triangle.

Top highlights of Triton Bay

  • Witness the docile and gentle whale sharks nibbling on the small fish from the bagans in one of the areas where whale sharks do not migrate.
  • Hunt for some of Triton Bay’s endemic species, such as wobbegong sharks, Triton Bay epaulette sharks, and Nursalim’s flasher wrasse, during the dive.
  • Look carefully among the reef for four different species of Pygmy seahorse discovered in the region.
  • See the huge black coral bushes formed a unique formation only in Triton Bay.

About Triton Bay

Triton Bay area was never paid attention to until 2006. And then, in 2008, the region was declared a marine protected region. Relatively new to the dive scene, Triton Bay soon caught up with Raja Ampat and Cenderawasih Bay with its marine biodiversity and completed the Bird’s Head Seascape trifecta.

Located in the Kaimana regency, Triton Bay lies about 30 nautical miles from the town of Kaiman in West Papua. The sheltered location of Triton Bay helps maintain the richness of the underwater life and has been deemed as the last frontier of diving destination in Indonesia.

Diving in Triton Bay

One of the few distinctions between Triton Bay and Raja Ampat lies in visibility. Triton Bay is not known for excellent visibility due to the high level of nutrients, but this condition makes up for the abundance of fish life.

Giant groupers, Napoleon wrasse, schooling of jacks, barracudas, fusiliers, surgeonfish, bumphead parrotfish, rabbitfish, and tuna are just some of the hundreds of fish species that can be found in Triton Bay. They manoeuvre among the various soft and hard corals, forming giant formations, including those massive black corals in red, yellow, and brown, creating a harmony of colors underwater.

As one of the areas forming Bird’s Head Seascape and the epicenter of The Coral Triangle, some endemic species have made this area their home. From Nursalim’s flasher wrasse, Triton Bay epaulette shark, and Wobbegong sharks to Erdmann’s tilefish, Jamal’s dottyback, Mercy’s garden eel, Papuan garden eel, and Bird’s Head jawfish, these marine animals only live around Triton Bay and nowhere else, proving the diversity is well-defined.

Look for the big players like whale sharks, pilot whales, rays, and dolphins in the deeper water of Triton Bay and be mesmerized by their presence. This region also boasts many macro creatures like frogfish, ghost pipefish, wunderpus octopus, nudibranchs, and pygmy seahorses. Four of the seven seahorse species (Bargibant’s, Pontoh, Satami, and Denise) are often seen camouflaging and hiding between the crooks of the coral reefs, waiting to be spotted.

The Speckled Giant of Triton Bay

Like Cenderawasih Bay, the whale sharks in Triton Bay have built a unique mutual relationship with the fishermen. These gentle giants can be observed year-round thanks to the large bamboo platform known as bagans. Even though whale sharks rarely stay in one area, the ones in Triton Bay are an exception. They choose to spend most of their time in the region.

At night, the fishermen will lower the nets, turn on the lights to attract fish and lift the nets from the bagans before sunrise. Over the years, the whale sharks follow the nets to the surface and nibble on the small fish. The fishermen believe the whale sharks bring fortune to their catch, and interestingly, it’s not merely an assumption. The reason is that the presence of whale sharks, in turn, attracts important fish for fishermen, such as anchovies, tuna, and mackerel, to the waters where they feed. This habit is also an indicator of nutrient- dense water and plays a role in balancing the food chain.

This collaborative nature is not only beneficial for fishermen or the whale sharks but also for conservationists. They can tag and monitor the whale sharks to learn more about their migration pattern, which ultimately helps conservation efforts.

The encounters with these speckled megafaunas are not guaranteed as the bagans target different fish species, depending on the time of the year. The dark moon period is considered the best time to see these gentle giants, and sometimes dolphins can be seen lurking around the bagans. And they can only be seen in the early morning.

The whale sharks are known for their docile and gentle nature, but keeping the distance when encountering them is still essential.

Diving Environments in Triton Bay

The choice to dive in Triton Bay is endless, not only because of the diversity of the marine life but also the topography. Everything is available in Triton Bay, from pinnacles to boulders, dramatic overhangs and caverns, with reef diving taking the hot spot. Triton Bay does not neglect those critters hunters as some dive sites cater to those who love macro creatures.

The water temperature in the region is within the constant range of 26 to 29 degrees Celsius. Still, it can drop to around 24, especially during the monsoon season, which occurs from June to September. Many of the dive sites in Triton Bay are on the shallow side, with depths ranging from 5 to 35 meters. Even without going deeper than 20 meters, the coral garden, schooling of fish in every color, shape, and species, already shows their magnificence.

The visibility in Triton Bay is varied, but generally, it can be expected to be in the range of 10-15 meters. It can fall to 5 or over 25 meters, depending on the weather and the currents. The currents in this region are generally strong, so it is important to check the condition beforehand and follow the diving instructor’s guidance.

How to get to Triton Bay

The entry point to Triton Bay is through Utarom Airport in Kaimana, the regency of Triton Bay. Getting to Triton Bay requires multiple stops as no direct flight is available to reach this area in West Papua, which is considered quite remote by Indonesian standards.

Makassar will be the first stop if you fly from Jakarta. Then, it will be followed by the flight to Sorong as the second stopover. If you want to fly directly to Kaimana, only Wings Air has this route. If you take Lion Air or Batik Air from Sorong, the flights will have another stopover in Manokwari before heading to Kaimana via Wings Air.

If you fly from Denpasar-Bali, the flight will have a stopover in Surabaya, followed by a flight to Makassar. From then on, the flight will fly to Sorong before making Kaimana the last stop.

Diving Seasons & Weather in Triton Bay

Triton Bay experiences two wet seasons, which occur from November to December and then from July to August. The southeast monsoon season, which lasts from June to September, brings strong winds and is not ideal for diving due to rough conditions.

The immediate period after the monsoon is recommended for diving, making it the start of diving season, which starts in October and lasts until early June. Though the visibility is less, the water is calm. December to May brings in the best visibility in the area, and the water is warmer, averaging 30 degrees Celsius.

Rain is possible even outside the rainy season in West Papua.
