Halmahera
Indonesia · Maluku
Remote and rarely dived, Halmahera sits at the heart of the Coral Triangle and harbours extraordinary biodiversity including walking epaulette sharks, pygmy seahorses, and manta rays funnelling through the island's narrow passages. Its isolation has kept reefs in near-pristine condition.
