The Baths on Virgin Gorda in the British Virgin Islands. About 50 min. boat ride from St. Thomas and St. John.
There are natural grottoes where the rocks and boulders the size of houses, are stacked on top of each other to create natural pools so the water flows in from the beach. Its like a maze of walk ways and trails that wind through the shoreline and beach. We got to play around in a few. This is one of only 3 places in the world where these rock formation happen. Pretty cool stuff.
