Cayo Levisa is an isolated little island accessible only by boat. The island is around 3km (1 3/4 miles) long and just several hundred yards wide at most points. The entire northern shore of Cayo Levisa is one long stretch of white sand fronting a calm and startlingly turquoise blue sea. The beach is backed alternately by small stands of pine trees and stretches of thick mangrove. There's excellent bird-watching and scuba diving here. Cayo Levisa is part of the Archipiélago de los Colorados, which includes Cayo Paraíso, an even smaller little island reputed to have been a favorite fishing haunt of Ernest Hemingway.

Several Havana, Pinar del Río, and Viñales tour agencies run day tours to Cayo Levisa, so the island's resort and beaches can fill up with 50 to 100 extra visitors between 10:30am and 5pm in high season. But if you spend the night, you'll feel like you've got the island to yourself.
