Beginner-friendly Kerama coral-garden dive off Aka Island.
Adan Shita is a gentle Kerama boat dive off an uninhabited island near Aka where divers follow shallow coral gardens and sandy patches in clear water suited to easy training, check dives, and relaxed fish watching. The site is valued for its beginner-friendly profile and healthy reef scenery, with clownfish, goatfish, damselfish, nudibranchs, and occasional leaf scorpionfish or eels rewarding slow passes over the coral.
Site Conditions
Safety Notes
Adan Shita is generally an easy boat dive, but the shallow coral garden still rewards careful buoyancy and fin control to avoid damaging reef structure.
Access Restrictions
Adan Shita is reached by dive boat from Aka Island or nearby Kerama operators rather than by independent shore entry.
Legal Notes
As with other Kerama dive sites, site selection and mooring use depend on local operator practice, weather, and marine-park style protections around the islands.
