Experience the thrill of scuba diving and snorkeling around the Andros Barrier Reef, the third-largest living organism on earth. The 190-mile-long reef starts out along the east coast of Andros, so it’s easily accessed. Swim out—the reef is only eight feet below the water’s surface on the island side, but on its far side, it drops off into a deep ocean trench called the Tongue of the Ocean. Along the reef, you’ll see a range of impressive big fish like sailfish and manta rays, as well as dozens of other types of colorful fish, plants, and coral.
