Onna Point is a shore-access reef maze with current-sensitive crevasses.
Onna Point is a shore-access reef dive in Onna Village, Okinawa, known for coral-packed channels and narrow crevasses. The site feels like a maze, with swim-throughs and tunnel-like cuts that reward slow navigation and solid buoyancy. Access is rough once the pavement ends, and the reef can funnel current through the entry and exit, so tide timing matters. Divers come here for hard coral, turtles, snappers, clownfish, angelfish, wrasses, and other reef life.

Treat the crevasse entry as current-sensitive and do not assume the exit will be easier than the entry. This is a better site for divers comfortable with reef navigation.
