Sardine Reef is Raja Ampat’s fish-packed boat drift reef.
Sardine Reef is a boat-access Raja Ampat reef hill in the Dampier Strait, famous for dense fish action and rich coral growth. The reef rises from a deeper slope to a shallow top, so the dive feels like a moving vertical scene rather than a flat reef tour. It suits advanced divers who are happy to time the current and want a high-energy drift with sharks, schooling fish, and vivid coral structure.
