One of the most visited sites in the British Virgin Islands is the Baths, a series of massive boulders at the shore’s edge. They form a labyrinth that leads to a small beach, fronting a tranquil cove of water. To access that beach, it takes about 15 minutes of climbing over and squeezing through narrow openings between the huge boulders. Most of the climbs are relatively easy, but a few require a bit more stamina. The reward: swimming in the calm cove. But beware that, on cruise ship days, crowds swarm the Baths, especially in the morning.
