The Blue Cave:

How to get to the beach: just follow Google Maps.

How to get to the blue cave: first, have a look to the exact location Google Map. Although the cave is accessible from the north side, just swimming a bit, it’s almost impossible to park, and very crowded with large tour operators and big groups.
We strongly recommend that you swim from Yoneraha beach to the Blue cave. It’s an amazing snorkeling experience with lots of coral and fish to see.
