Belize is a black hole of great dives—you can get lost in all the options here. What else would one expect from the Belize Reef, the second largest barrier reef in the world? And one of the sites that contribute to its magnificence is a 412-foot trough in the reef called the Blue Hole. Just minutes by boat from Ambergris Caye, the diving is as accessible as it is thrilling.

For years Belize was shrouded in anonymity; it was always there, but few noticed it. Its popularity surged around the mid-90’s once word got out about the "unspoiled" barrier reef that thrives there.

Not only is the diving top-notch, onshore activities are always second to none. Mayan ruins and pristine rain forests are worthy of taking in once your skin becomes too wrinkled from underwater exploration.
