Dive-site story
What makes this site worth diving
Diving at Zamami Island in the Kerama Archipelago covers hard coral formations, shallow white-sand channels, and steep reef slopes in water known locally as Kerama Blue. Sites sit a short boat ride from Zamami Port, ranging from sheltered coral gardens with seagrass-grazing green sea turtles to exposed pinnacles in mild currents. Humpback whales migrate through surrounding channels each winter, while summer delivers warm water and minimal swell.
