Tankah Tres Guide: Cenote Manatí's Mangrove Lagoon, Snorkeling, and Riviera Maya Adventures
Nestled at the end of a sandy road, the serene hamlet of Tankah Tres (also known as Tankah Bay) offers a tranquil seaside escape in Mexico's Riviera Maya. This community of vacation homes and boutique hotels overlooks a stunning cove. Behind it lies a lush mangrove forest hiding the area's crown jewel: Cenote Manatí (also called Casa Cenote). Named for the manatees that once graced its waters, this unique open-air cenote stands apart from typical sinkholes. Unlike standard swimming holes, its crystal-clear waters meander like a river through the mangroves, with twisted roots reaching into the depths. One end connects to Sac Aktun, one of the world's longest underwater cave systems, while the other links via a 500m rocky tunnel to the Caribbean Sea. This freshwater-saltwater convergence creates a mesmerizing halocline effect, blending layers for breathtaking underwater vistas and drawing diverse marine life rarely seen in cenotes—from green moray eels and tarpon to blue crabs, guppies, and even occasional small crocodiles basking on the banks.
Top Activities at Tankah Tres
Snorkeling
Snorkeling is the highlight for most visitors. With visibility often exceeding 20 meters, fish schools glide as if through air. Rent gear on-site (M$400) or purchase affordable sets at supermarkets like Chedraui in Tulum. Even without equipment, swimming amid treeline views, egrets, and surface-level fish is delightful. Guided tours (M$600, gear included) are available but unnecessary—the 250m cenote is straightforward to explore independently.
Scuba Diving
Beginners appreciate the shallow 8m depths for open-water certification, while experts navigate mangrove tunnels and overhangs. Advanced cave divers can access the Caribbean tunnel for an otherworldly swim. Book with Tankah Divers Tulum nearby or Tulum dive shops offering transport.
Kayaking
Rent two-person kayaks hourly (M$300), but crowds can limit space. Visit early morning or late afternoon for calmer waters and fewer swimmers.
Beachcombing
Across from Cenote Manatí, Tankah Tres' oceanfront beckons. Purchase a drink at a beachside restaurant for access to the tawny sands, tide pools, and protected bay. Snorkel near the southern reef for vibrant fish and sea turtles.
Essentials to Bring
Amenities are basic, so pack towels, snorkel gear, and rash guards or t-shirts (no sunscreen allowed, even biodegradable). Water shoes help with rocky ocean entries. Bring cash for entry fees and return transport.
