Casa Cenote — Cenote Snorkeling in Tulum

Casa Cenote offers a snorkeling experience found nowhere else in the Yucatan Peninsula. Rather than peering down into an underground cavern, you float through an open-air river channel that winds through a cathedral of towering mangrove trees, their roots plunging into water so clear you can count individual grains of sand on the bottom. Located where the underground river system meets the Caribbean Sea near Tulum, Casa Cenote is a living, breathing ecosystem teeming with wildlife that makes every moment in the water a discovery.

Sea turtles are the stars of the show at Casa Cenote, and spotting them gliding gracefully beneath you is a highlight that delights snorkelers of all ages. But the wildlife does not stop there — tropical fish in brilliant colors dart between the mangrove roots, baby barracuda patrol the channels, and the mixing of fresh and salt water creates a unique habitat where both freshwater and marine species coexist. The channel varies from 2 to 7 meters deep, and the clarity is remarkable throughout.

What makes Casa Cenote truly exceptional for snorkeling tours is the bonus of ocean access. Cross the coastal road and you reach the beach, where the nearshore reef offers an entirely different snorkeling ecosystem — coral formations, tropical reef fish, and occasionally rays and larger sea turtles. This combination of cenote and ocean snorkeling in a single visit is unique to Casa Cenote and represents outstanding value. The site features comfortable wooden docks for entry, shaded picnic areas under the mangroves, and an overall atmosphere that is both wild and welcoming.
