Biodiversity, dialled up

One voyage. All the headline reefs.

Cruise aboard the iconic Dewi Nusantara and cover the full sweep of Raja Ampat—from Misool’s soft-coral cathedrals to the manta stations of Dampier Strait and the secluded bays up north. You’ll dive kaleidoscopic reefs bursting with schooling fish, encounter reef mantas and oceanic mantas in season, and surface to glassy lagoons framed by limestone towers. Camera in hand or not, this is the Indonesian epic: long bottom times, warm water, first-light and last-light dives, and an onboard crew that runs a smooth, safety-first operation while keeping the vibe relaxed and unhurried.

🐠 Peak Manta Season: Warm seas, generally calmer conditions, prime chances for manta action at cleaning stations and feeding sites.
🐠 Calm Ocean, Lush Reefs: Good visibility, fewer boats, rich reef life. Great time if you like quieter sites with plenty of colour.
🐠 Balanced Conditions: Settled seas, biodiversity in full swing, a sweet time for “a bit of everything”.
