Gran Cenote
Just three miles (five kilometers) from central Tulum, the Gran Cenote is very popular with swimmers and snorkelers of all ages. Partially submerged tunnels connect the cenote’s open-air sections. The location is very popular with divers, as it provides access to the world’s second-largest cave system. With its sandy bottom and sunbathing decks, the Gran Cenote is also a favorite with swimmers and those looking to relax in the sun. Keep an eye out for bats and even occasional toucans.
