Nita Cave is a boat-access topography dive on the north side of Zamami Island in the Kerama Islands, built around intricate caves, tunnels, and arches that turn into strong light-show scenery at the right time of day. The site suits divers who like controlled buoyancy and clean route planning more than a simple reef cruise, and the surrounding terrain adds schools of cavern fish, longnose hawkfish, and small critters tucked into the rockwork.
