This Mayan snorkel adventure tour brings you to the amazing Yal Ku Lagoon in Akumal, an ocean inlet full of gorgeous tropical fish and vegetation. Next stop is an open cenote in the middle of the jungle were you can marvel at the lush vegetation and crystal clear waters and snorkel in the underground river and explore what the Mayans considered the entrance into the underworld. These freshwater “swimming sinkholes” are carved into the limestone over millions of years creating stunning rock formations and the perfect place to refresh in the jungle.
