Cendrawasih Bay, Indonesia's largest marine national park, opens off the coast of West Papua into deep water where whale sharks gather year-round around traditional bagan fishing platforms, often coming close enough to snorkel alongside. Beyond the whale sharks, the bay's reefs, mangroves, and remote islands remain some of the least-visited in the entire Coral Triangle.

Traveler reviews

★★★★★

Snorkelling beside whale sharks the size of buses, just metres from a fishing platform, was one of the best wildlife experiences of my life. Getting there takes effort but it's worth every connection.

Felix A. · November 2023

★★★★★

Did this as part of a liveaboard from Sorong. The whale shark encounters at Kwatisore were incredible and the reefs we dived afterwards were untouched and full of life.

Sandra K. · March 2024

★★★★☆

Logistics are the hardest part, flights, charters, timing, but the local fishermen know exactly where the whale sharks will be each morning. Unforgettable.
