Guanaja is one of the Bay Islands of Honduras, and is in the Caribbean. It is located about 70 km off the north coast of Honduras. One of the cays off Guanaja, also called Guanaja or Bonnaca (or just simply, The Cay), is just off the main island, and contains most of the 10,000 or so people who live in Guanaja. The cay has been described as the Venice of Honduras because of the waterways that run through it. It is completely packed with people and their houses.
Guanaja is often visited by divers and has warm, clear waters that support a beautiful coral reef. This reef is part of the 2nd largest coral reef in the world, second only to the Great Barrier Reef off Australia.
