About this site
Sangalaki is a sand cay in the Derawan Archipelago, Indonesia, and a beginner dive. The average depth is 10 metres and the maximum is 20 metres. It is reached by day boat or liveaboard, and the best months run from March to October.
Reef manta rays are the draw here. The local manta population feeds actively near the surface and is now protected by a new radar system, following years of poaching.
