Hol Chan is famous for its wide variety of lush marine life. Hol Chan has been a marine reserve since May 2, 1987. It covers about 3 square miles with some areas being about 5 feet deep while the channel is about 30 feet deep. Snorkelers can be on the lookout to see corals, sharks, stingrays, turtles, puffer fish, eels, parrotfish, angelfish, barracuda, and even the seasonal manatee. You can observe them from the boat or take the adrenaline rush of jumping in and exploring their amazing underwater world.
