Utila (Spanish: Isla de 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. It has been documented in history since Columbus' fourth voyage.
Roatán (Spanish pronunciation: [ro.aˈtan]) is an island in the Caribbean, about 65 kilometres (40 mi) off the northern coast of Honduras. The largest of the Bay Islands of Honduras, it is located between the islands of Utila and Guanaja. It is approximately 59 kilometres (37 mi) long, and less than 8 kilometres (5.0 mi) across at its widest point. The island consists of two municipalities: José Santos Guardiola in the east and Roatán, including the Cayos Cochinos, in the west. The island was formerly known in English as Ruatan and Rattan.
