10. The Baths to Devil’s Bay and the Cathedral, Virgin Gorda

Most cruisers to Virgin Gorda find their way to the Baths, an array of pools and grottoes created by huge granite boulders. If sitting and soaking aren't for you, there’s an easy, 15-minute trail to lovely Devil’s Bay on the island’s southwestern tip. (Name notwithstanding, it’s a tranquil spot for swimming and snorkeling.) A separate path wends through the Cathedral, where boulders touch overhead, creating small pools with shafts of light peeking through. Expect to crawl, climb ladders, and wade through shallow water.
