Cenote Azul or Blue Cenote is located in Puerto Aventuras, Mexico, and is a unique natural formation created when an underground river collapsed to form an oasis of crystal-clear freshwater. This cenote is quite easy to get to and is situated just off the Chetumal-Cancun Highway in the Mayan Riviera of Quintana Roo. Visitors can enjoy swimming and snorkeling in the cool waters or simply take in the tranquil atmosphere of this special place
