Utila is the smallest of Honduras' major Bay Islands, after Roatán and Guanaja, in a region that marks the south end of the Mesoamerican Barrier Reef System, the second-largest in the world.
The eastern end of the island is capped by a thin veneer of basaltic volcanic rocks, erupted from several pyroclastic cones including 74 m Pumpkin Hill which forms the highest point on the island. It has been documented in history since Columbus' fourth voyage, and currently enjoys growing tourism with emphasis on recreational diving and is known as one of the world's best dive locations.
Utila was also the home of the annual festival Sunjam. Sunjam is the largest electronic music event in Honduras, and one of the largest and most important in Central America. The date is fixed to the first Saturday of August every year. The event attracts world class international DJs as headliners and invites the best regional talent to perform.
