The quick ride out to Hol Chan Marine Reserve makes this the most popular half-day tour for visitors staying at Ambergris Caye and Caye Caulker. Set aside in 1987, this reserve covers an area of 3 square miles (7.8 sq km) and is found off the southern tip of Ambergris Caye. As a result, this area of the Belize Barrier Reef supports healthy populations of fish and colorful coral. Turtles, nurse sharks, grouper, jacks, reef fish, and barracuda are just a few of the species you might see here. The reef ranges from 10–30 feet (3–9 m) deep and most guides take snorkelers along the outer edge of the reef. While this site is great for beginner snorkelers, as well as divers, swimmers should pay attention to currents which can be strong throughout the reserve.
