The Baths

"The Baths", located on the island of Virgin Gorda in the British Virgin Islands, is testament to the Caribbean's volcanic and tectonic origins. The predominant rocks forming most Caribbean islands are basaltic from eruptive volcanos and these granitic rocks formed deep beneath in the Earth's mantle and have been uplifted to the surface and subsequently eroded to their present shapes. This kind of rock is found only in a few places in the Caribbean. The name The Baths refers to their origin from the batholith. 

The largest boulders are about 40 feet long and they form tunnels, grottos, and tidal pools. In the image above we are standing in one of the grottos, a picturesque room called the Cathedral.
