Sumisaki rewards a relaxed boat dive around the anchor pinnacle and nearby heads; current is usually mild, so it suits fish watching and macro work.
About Sumisaki
Sumisaki is a boat dive in Kushimoto built around a central pinnacle with scattered outlying heads and a sandier slope to the north. The site is known for calm water, light current, and steady fish action, making it a good choice for relaxed reef-style diving, macro photography, and divers who want a simple guided route around structure rather than a high-workload drift. It is the kind of Kushimoto site where slow, careful buoyancy pays off.
