About this spot
Sangalaki Manta Channel sits off Sangalaki Island in East Kalimantan's Berau Regency. The site draws divers to depths between 5 and 25 meters, where manta rays are the main attraction. The channel creates natural feeding conditions that bring mantas to the area, making this a premier destination for manta encounters in Indonesian waters. The dive works best for intermediate-level divers comfortable with moderate depth and current. The site operates year-round, giving you flexibility to plan when it suits your schedule. Three community videos document dives here, providing useful reference for what to expect before you arrive. Access from Sangalaki Island is straightforward, and the spot sits outside any marine protected area, meaning standard dive operator protocols apply. Plan dives with local guides familiar with manta behavior and current patterns. The channel's depth range and manta aggregations make it a solid choice for divers wanting to see large pelagic species in their natural habitat.
