Triton Bay

Triton Bay, located in Kaimana Regency, West Papua, stands as one of the world's most pristine biodiversity hotspots with over 1,400 fish species and 500 coral species documented in this relatively small area. This protected bay system encompasses over 600 square kilometers of untouched coral reefs, underwater seamounts, and coastal mangroves where marine biologists continue discovering new species with each expedition.

Triton Bay offers one of the world's premier diving destinations for whale shark encounters and endemic species, featuring year-round resident whale sharks at traditional fishing platforms (bagans), walking sharks, unique soft corals, and marine life densities found nowhere else on Earth. The bay's protected geography creates stable diving conditions with mild currents, making it accessible while delivering extraordinary underwater biodiversity encounters. Liveaboard diving in Indonesia provides the ideal way to explore this remote marine sanctuary.

Most liveaboards embark or disembark from Kaimana (accessible via Sorong or Ambon with connecting flights), often as part of extended itineraries combining Triton Bay with southern Raja Ampat's Misool region. Liveaboard options range from vessels starting at $350/day to luxury expedition boats reaching $700+/day, with options suitable for all experience levels from beginners to advanced divers.

Diving Regions

Triton Bay (Whale Sharks & Endemic Species)

The main bay features traditional fishing platforms (bagans) near Namatote that attract year-round resident whale shark populations feeding on baitfish. Unlike seasonal migratory populations elsewhere, Triton Bay's whale sharks remain in the bay throughout the year, offering reliable encounters where multiple individuals often gather. Beyond whale sharks, the protected bay sites offer exceptional macro photography opportunities with walking sharks, pygmy seahorses, mantis shrimp, and rare nudibranch species. Little Komodo, famous for its vibrant soft coral gardens, provides stunning wide-angle photography and diverse marine life encounters. These sites suit all certification levels with mild currents and stable conditions.

Momon Headland (Dramatic Walls & Kiti-Kiti Waterfall)

Momon Headland features dramatic underwater topography with steep walls dropping into deep channels and vibrant soft coral gardens. The region's most iconic feature is the spectacular Kiti-Kiti waterfall cascading directly into the ocean, creating a stunning backdrop for surface intervals and photography. The headland's exposed position attracts pelagic species including manta rays, eagle rays, and schooling fish aggregations alongside healthy hard coral formations. This region suits intermediate to advanced divers comfortable with occasional stronger currents at pinnacles and exposed reef sections.
