Ambergris Caye hovers in a vacation sweet spot: just enough amenities to make it exciting, but not so overdeveloped that you’re tripping over flip-flopped tourists.

Reef divers drool over the Belize Barrier Reef and the Blue Hole, a 400-feet deep circle of limestone that teems with angelfish, elkhorn coral, cleaner shrimp and stalactites.
