About Cape Maeda
Cape Maeda sits at the southern tip of Onna Bay, on a promontory of coral rock with low cliffs over the sea. It is one of Okinawa’s best-known dive spots for its clear water, reefs close to shore and the Blue Cave, a sea cave opened at the base of the cliff.
Inside the cave, light entering through the submerged opening reflects off the sandy bottom and makes the water bright blue, especially on sunny mornings. Outside, the reefs host colorful tropical fish like clownfish and butterflyfish, and sometimes sea turtles. Access to the water is via a long concrete stairway that descends from the parking area to the rocks, where you enter the sea.
Most visitors snorkel or scuba dive with local operators who provide equipment, a guide and often the boat, because swimming to the cave requires experience when there is current. When the wind comes from the north or there is swell, the stairway entry is often closed by management, and tours run by boat or are cancelled.
At the top of the cape there is a viewpoint with views of the coast toward Cape Manzamo, parking and shops run by the operators. The area is sought after from early morning, especially in summer.
