Manzamo: Okinawa boat-diving area with Dream Hole.
Boat selection depends on wind, waves, current, and diver level.
Manzamo is an Onna Village boat-diving area best known for Dream Hole, a dramatic cave route with strong current and plenty of macro life. The area also includes easier reef sections, so divers can choose between relaxed reef work and a more challenging overhead-style line. Short runs from Seragaki Port keep the logistics compact, but the signature route still calls for buoyancy control and a guide who knows the local conditions.
