About this site
Near Ishigaki, this site features a stunning coral-covered pinnacle rising from the depths. Schools of longfin batfish swirl around the structure, creating a mesmerizing spectacle. The clear waters offer excellent visibility, with occasional reef sharks and turtles passing by. Strong currents can occur, making it ideal for drift diving. Vibrant soft corals and sea fans add color, while deeper sections reveal dramatic drop-offs. Best suited for intermediate to advanced divers due to variable conditions.
