Ternate
Indonesia · Maluku
A volcanic island in North Maluku where Gamalama's flanks plunge beneath the sea as sheer black-sand slopes and pristine reef walls. Ternate sits at the heart of the Coral Triangle with exceptional macro life on its muck sites and healthy walls draped in soft corals and sea fans. The island's remoteness keeps dive pressure low and biodiversity extraordinarily high.
