About this site
This dive site off Siau Island features dramatic volcanic slopes plunging into the Celebes Sea. Black sand slopes give way to vibrant coral gardens teeming with reef fish, pygmy seahorses, and occasional reef sharks. Strong currents attract pelagics like tuna and barracuda. The site offers excellent visibility and warm water year-round, with occasional thermoclines. Volcanic activity nearby sometimes creates unique bubble streams from the seafloor. Best suited for intermediate divers due to variable conditions.
