About this site
Batu Reef sits off Sulawesi, Indonesia, in the waters near the northern tip of the island close to the Bunaken and Bangka area. The coastline here is dotted with volcanic islands and fringing reef, typically accessed by small boat from coastal dive operations in the region. The dive reaches a maximum depth of around 30 metres and is rated intermediate. Divers have reported strong currents at times, along with sightings of eagle rays and trevally moving over the reef.
