View of one of the pools of the Gran Cenote. Situated in the lush Yucatan jungle, just a few kilometers west of Tulum, Mexico, the Gran Cenote is a complex of several cenotes that are connected by little natural channels. The water in the cenotes is so crystal clear that you can see the abundant underwater wildlife here even without the snorkeling mask. However, you are recommended to bring your snorkeling gear because you can snorkel with turtles here.
