The Gran Cenote Tulum or Grand Cenote is one of the most famous and most visited cenotes on the Riviera Maya in Mexico. The turquoise water is crystal clear and ideal for snorkeling. Both smaller fish and turtles are swimming in the beautiful cenote, from which you can reach the different depths of water via a wooden deck. You have the choice to enter several entrances to the cave, the turtle pool, or the grotto. An elongated cave connects two parts of the complex through which you can dive. It’s definitely worth bringing a pair of diving goggles, even if you can rent them on site for a surcharge.
