The 700-mile Mesoamerican Barrier Reef System is the world's second largest, and the 190-mile long Belize Barrier Reef (top) is a part of that. Lying from 980 feet to 25 miles off the coast, with underwater caves, more than 100 types of coral and more than 500 species of fish. Top spots include the Bay Islands of Roatán and Utila, along with Ambergris Caye and Caye Caulker. You can also opt to snorkel right off the shore at mainland resort areas like Plasencia. Apart from a riot of tropical fish like yellowtail damsels, barred hamlets, and angelfish, you'll also likely spot sharks, stingrays, sea turtles, and even West Indian manatees.
