Cape Maeda (Blue Cave)
真栄田岬（青の洞窟）
A sea-eroded cave beneath a cliff at Cape Maeda in Onna Village, where sunlight through the seawater turns the cave a glowing blue; it is Okinawa's most popular snorkeling and experience diving spot.
The Blue Cave lies beneath the cliffs of Cape Maeda. From the steps on the shore, it takes about 5 minutes to swim to the cave entrance. Inside, sunlight refracted through the water turns it a dreamy fluorescent blue, and tropical fish can be fed in the surrounding area. Most visitors join snorkeling or experience dive tours run by local shops, which include equipment, an instructor and photos and cost about 4,000 to 8,000 yen; boat dive routes are also available. The parking lot and showers on the cape are paid, and the entry point closes when waves are high, so consider booking flexibly in case you need to reschedule. It is about 1 hour's drive from Naha.
