Drift over some of the healthiest coral gardens remaining anywhere on Earth, alive with pygmy seahorses, wobbegong sharks, and iridescent schools of anthias. Cenderawasih's remoteness has kept these reefs in near-pristine condition.
What to expect
The tender drops you at a sheltered bommie selected for the day's conditions — glassy water, minimal current — where you fin over table corals the size of dining tables and peer into caverns glowing with sea fans. Your guide free-dives to point out creatures hidden in plain sight, then surfaces to narrate the ecological relationships at play. Water temperature sits at a comfortable 28–30°C and visibility routinely exceeds 25 metres. The session ends with fresh coconut water on the beach of a deserted islet.
Good to know
No diving qualification needed — intermediate snorkel ability sufficient. Reef-safe sunscreen only; guides carry extra. Time your return carefully against the all-aboard; the reef sites are typically 20–40 minutes from the ship by tender.
