Boat-access Rainbow Arch site with soft corals and clear water.
S Point in Minami Ise is a boat-access calm-water site built around the Rainbow Arch, where soft-coral-covered terrain and easy navigation make it a relaxed but interesting dive. The arch and surrounding slopes deliver both wide-angle scenery and macro subjects, so it works well for photographers, newer divers, and anyone who wants a clear-water site with plenty of texture. It is the kind of dive that rewards slow pacing, steady buoyancy, and a return visit for different light conditions.
