Blue Cave Okinawa Snorkeling & Introductory Scuba Diving

Located under the limestone cliffs of Cape Maeda in Onna Village, the Blue Cave (Ao no Mokutsu) is a natural sea cave created by wave erosion. Sunlight enters the cave mouth underwater and reflects off the white limestone sand bottom, making the interior pool glow in an ethereal cobalt blue. Visitors can explore the cave via guided snorkeling, introductory scuba diving (no license required), or boat-entry charters directly from nearby ports like Maeda or Maekaneku.
