All the Bahamian islands boast abundant natural attractions. But Andros—the largest, yet most sparsely developed of all The Bahamas—is king when it comes to exceptional natural surroundings. Here, you’ll find the world’s third-largest fringing barrier reef, mesmerizing blue holes that some say are home to the mythical creature Lusca, the Tongue of the Ocean (a mile-deep abyss teeming with vibrant marine life) and numerous species of flora and fauna. If you’re an ecotraveler, kayaker, bird watcher, hiker, snorkeler, diver or fisher, Andros should be your first stop when visiting The Bahamas.
At 2,300 square miles, Andros is the largest island of The Bahamas and the fifth-largest island in the Caribbean. Its miles of deserted beaches and freshwater lakes play host to countless species of wildlife, marine life, flora and fauna. Andros is covered with vast areas of wetlands that create channels perfect for bonefishing. In fact, many consider Andros the Bonefishing Capital of The World. When visitors feel like taking a break from all the adventure, the island offers quaint settlements and secluded beaches known for their local charm and laid-back lifestyle.
