About this site
Black Rock is a pinnacle dive site in the waters off North Sulawesi, Indonesia, a region best known for the nearby Bunaken area and the Lembeh Strait. This part of the Celebes Sea is fed by strong currents that support a wide range of diving styles across the region, from coral slopes to muck sites. Black Rock itself is rated a beginner dive, making it an accessible option alongside the more current-driven sites the region is known for.
