The Baths is an area of unique geologic formations (batholiths) and one of the BVI's major tourist destinations.

Although volcanism accounts for much of the Virgin Islands, The Baths was formed by granite that eroded into piles of boulders on the beach.

[1] Granite forms from the slow cooling of magma at depth nowhere close to surface volcanoes.

Once exposed, erosion continued to isolate the granite into large boulders and round their surfaces.

The boulders form natural tidal pools, tunnels, arches, and scenic grottoes that are open to the sea.
