About Casa Cenote
Casa Cenote, also recognized as Cenote Manati, is a unique natural sinkhole situated approximately 10 kilometers north of Tulum on Mexico's Yucatán Peninsula, within Tankah Tres Bay. This site is distinguished as one of the few surface rivers in the region, forming a wide, open pool nestled within a mangrove field. It serves as the mouth of one of the extensive underground river systems, connecting to the ocean and providing a crucial link within the vast Sistema Sac Aktun. The cenote's topography is defined by its emerald, crystal-clear waters and an intricate ecosystem where mangrove roots and fronds descend into the water. Divers navigate through these natural formations, exploring tunnels, passages, and rocky overhangs that create the sensation of diving through a submerged jungle. The water column features a halocline where the cenote's cool freshwater meets warm saltwater from the ocean, creating visual effects at varying depths. This brackish environment supports a diverse array of marine life, including guppies, platys, mollies among the mangrove roots, and larger species like blue swimming crabs, green moray eels, barracudas, snapper, and tarpon. The site is also known for its resident Moreletii crocodile, Panchito, who often basks in the sun near the mangroves. Visibility is exceptionally good, often reaching up to 40 meters, making it ideal for observing this unique biodiversity. Casa Cenote is suitable for divers of all levels, including beginners, due to its generally calm conditions. It is often used for discover scuba diving experiences. Divers should focus on buoyancy control while exploring the site, which can be enjoyed throughout the year. Shore entry is typical for this riverine environment.

Conditions & Currents
Casa Cenote generally features calm conditions, making it suitable for divers of various experience levels. As an estuary that connects to the ocean, it has a mixing zone where freshwater meets saltwater, creating a halocline at different depths. Entry is typically from the shore, providing easy access. Visibility is consistently excellent, often extending up to 40 meters, though visual distortion can occur within the halocline layer. Surge is minimal due to the sheltered nature of the cenote. This site is particularly well-suited for buoyancy practice due to the presence of the halocline and the need to navigate around delicate mangrove roots and geological formations, making it a good choice for beginner divers and those refining their skills.
Why dive Casa Cenote from a liveaboard?
Casa Cenote is one of Mexico's signature dive sites. A liveaboard sleeps you on the water and puts you in the water for three to four guided dives per day, including dawn and night dives that day-boat operators rarely offer. You skip the daily commute back to port and reach quieter, less-crowded sites in the same region on a single trip.
Below are the liveaboards that include Casa Cenote on their Mexico itineraries.
