Cenotes, which are found only in this part of the world, have made the Riviera Maya's unique underground water system a diver’s Mecca for cenotes cavern and cave diving since 1987 when exploration of the Cenotes Dos Ojos started.
Under the jungles nearby Tulum lie the two longest underwater cave systems (Sac Actun 369km/230miles and Ox Bel Ha 285km/177miles) known on earth with spectacular formations and an amazingly clarity of the water.
Diving in a cenote is an unforgettable experience…pristine water that allows incredible visibility of more than 100m/300ft, flooded gigantic halls, rooms, and tunnels "decorated" with stalactites, stalagmites, columns and helectites (legacy of the ice age), in addition to archaeological remains, ancient paints, astonishing light beams, refraction effects, hydrogen sulfide clouds, and haloclines (where the fresh and the salt water meet).
Most of the caverns are accessible for divers with a miniumum of an Open Water Diver certification and without previous experience in an overhead environment.
And, with more than 1000 km/ 620 miles of guidelines, the area offers an unlimited number of cave dives for the certified cave diver.
