A cenote (from the Maya "ts'ono'ot" or cavern with water) is a cavern that was innundated as a result of the caving in of the roof of one or sevral caves. Subterranean waters gather in cenotes and form a sinkhole.The calrity of the water and the rock formations, which result from a long history of erosion, convert them into one of the most interesting and unique diving, swimming, or snorkeling experiences. They start out as an underground chamber that results from the dissolution of rock with rain water. As these caverns grow, the cenote reaches the surface via the collapse of the roof. Cenotes were formed during the lowering of the sea level caused by glaciar eras. The cenotes were formed during the widening of the subterranean river networks, as they made their way to the sea. Swimming in these natural spaces while wearin mosquito repellent or scunscreen affects the ecosystem significantly. Therefore, we ask you to use biodegradable products and to shower before jumping in.

Dos ojos refers to two neighboring cenotes that are connected by a large cavern and that seem to look into the subterranean river. The original explorations of this water system, one of the largest in the world, started in these cenotes. Dos Ojos was filmed for IMAX in 2002 and for BBC/Discovery in 2006. Dos Ojos is an excellent place to snorkel and for the first cenote dive for certified divers (it is possible to split the same group into diving and snorkeling tours).

Casa cenote is the mouth of a subterranean river that connects with the sea via a large cave. It is home to many young fish that seek refuge from sea currents inside its calm waters. It contains tarpoons, barracudas, blue crabs, and many other species. This beautiful cenote is surrounded by mangrove and is an ideal place to learn to dive and to snorkel, as it is not too deep and its waters are confined.

Carwash, or Aktun Ha, is an excellent cenote to swim, snorkel, and dive. It resembles a large pool with a diameter of 50 m and a depth of 3 m. In winter and spring, its waters become crystal clear (they are always good for diving) and you can admire an underwater garden filled with red-colored plants, fish, turtles, tree remains, and caves that go to a depth of 15 m. While diving in the waters of these caverns with an area of 185 m2 you can admire large stalactites and beautiful light shafts.
