Cape Maeda on Okinawa’s main island is best known for the Blue Cave, a sea cave that glows cobalt when sunlight filters through the opening. Shore entry uses a long stairway to reach the water, with an easy swim to the cave in calm conditions. Beyond the cave, the cape offers wall and reef sections that extend into deeper water, giving both beginners and experienced divers options. Boat entry is also used when conditions or crowding make shore access difficult.
