Cenote diving is one of the more unique experiences a certified SCUBA diver can have, as it offers a look into an ancient world, nearly untouched by all the years that have come after its formation. Many of these underground cave systems are still being discovered today, as the limestone surface of the Earth continues to erode and reveal these hidden caverns, which provides a wealth of opportunities for experienced and novice divers alike to see first-hand the shaping and little-changed environment concealed beneath an otherwise ordinary landscape.
As most cenotes are freshwater cisterns, there is usually little in the way of aquatic life, at least when compared to that of marine environments. However, Casa Cenote, also known as Cenote Manatee, is directly connected with the ocean, giving divers a chance to see freshwater and saltwater worlds collide. Within this cenote is a very distinct halocline, and marine fish species are abundant. Interesting limestone fissures and formations are one of the main attractions here, while the halocline and light filtering in from above make for a brilliant light show.
