Snorkeling at the second largest reef in the world? Yes, please! About a month ago I had the chance to visit Belize, a stunning country on the eastern coast of Central America. The Belize Barrier Reef spans 190 miles parallel to Belize's coastline, and is composed of offshore cayes, coral atolls, coastal lagoons, estuaries, mangrove forests, and all of the wonderful marine life that you can imagine.
