Mermaid's Grotto
Onna, Okinawa, JapanAbout this dive site
Explore the water around Okinawa
Short little walk through a wooded area and the Beach opens up for an amazing view. Photographers come here for the above water rock formations. Entry can be straight into the ocean. The best place to enter is to use the channel that was cut out as you can see in the map. It deep enough to start putting your fins on and kick out to the deeper spots. Be prepared to exit at another location and return to vehicle by foot. Its located in the Onna area. Dive site is classified as a level 5 (easy 1 to 5 hard). Parking on the road is limited.

Highly recommend. Parking is limited as there's no parking lot. Everyone parks on the side of the road so it can be quite the walk if there's a lot of people parked.
