  • Avoid at all costs. OVERCROWDED to the point of being dangerous. You cannot possibly enjoy this site as all serenity has been removed by the OVERCROWDING. You will find people all around you...

  • Awesome place to come visit for snorkeling and or diving. Unseated is neat and you can really take in the beauty. There is also some cool tunnels to get into the cave. Watch out for all the tourists.....  more

  • Absolutely loved it. Definitely should be on your to do list in Okinawa. It’s difficult to access so you’ll need a guide with a boat to drop you nearby and take you in the cave. The light reflects into the water causing a blue hue. Plenty of fish to see and a great snokeling spot.
  • Really far from Naha but exceptionally beautiful! Totally worth the treck. However, it doesn’t have soft sand when you’re entering the water and there’s lots of fish with coral reef’s. So I suggest bringing swimming shoes for protection. My feet got pretty banged up
