With more than 400 shipwrecks and its fair share of coral reefs, St. Kitts is a favorite of the scuba set. To try your hand at the hobby, consider staying at Bird Rock Beach Hotel, which houses one of the island’s most popular dive operators. Here, guests can charter a boat to nearby Devil’s Cave and swim among barracuda, lobsters, and nurse sharks, then retire to one of 46 tropical-hued rooms overlooking the sea. Less adventurous travelers can visit the on-site dolphin park, sunbathe on the private beach, or simply sip rum punches from the pool’s swim-up bar. Hotel staff is also happy to arrange off-site activities like catamaran cruises, rainforest treks, and volcano crater tours.
