The best place to Snorkel in Cozumel has to be Chankanaab Park. A state park that charges an entrance fee of $10.00, it is well worth it. The park itself is immaculate, staff cleaning, pruning the plants & racking the grounds. Lockers & showers are available as well as a taxi stand at the entrance. Just a few miles from the Port of Cozumel. A must stop for anyone who wants to Snorkel, Snuba, Scuba Dive or even swim with the Dolphins.
