The Two Eyes: Swimming & Snorkeling Zones

The main swimming areas feature two connected open-air sinkholes.

These clear freshwater pools give the cenote its name. The water stays at a constant 77°F (25°C) all year round.

You must wear a mandatory life jacket to swim in the designated clear water zones. Sunscreen and insect repellents are strictly prohibited to protect the cave ecosystem.

Wooden Boardwalks
