Guanaja is one of the Bay Islands of Honduras and is in the Caribbean. It is about 70 kilometres off the north coast of Honduras, and 12 kilometres from the island of Roatan. One of the cays off Guanaja, also called Guanaja or Bonacca or Low Cay, is near the main island, and contains most of the approximately 5,538 people who live in Guanaja. The densely populated cay has been described as the Venice of Honduras because of the waterways that run through it.
