You can get to Komaka Island by high-speed boat from the Chinen Kai-yo Leisure Center. Atop low hills, Adan (screw pine) trees, and other trees form a landscape of green. Each year at the beginning of summer, sea birds flock here to lay their eggs and raise their young. The shallow sea stretches forever. In the shoals, you can see coral reefs and tropical fish you could almost catch in your hands. It is a great spot for snorkeling, diving and wind surfing. There are toilets and changing rooms.
