Utila is a small Caribbean island off the coast of Honduras in Central America. It's part of a system called the Great Mayan Reef, which also includes the nearby islands of Roatán and Guanaja. These three islands, known as the Bay Islands, represent the southern end of the great reef, the second largest such structure in the world. For this reason, the Bay Islands offer some of the world's best diving waters. In this video by contributor Leogiraudeau, you'll get a bird's eye view of Utila.
