Cenote Koi is part of the K’oox Baal cave system (including the Tux Kapaxa system).
Between 2006 and 2011, cave divers explored more than 30 km of new cave passages in the K’oox Baal system. On December 9, 2011, the two cave systems merged and became known as K’oox Baal. Already an impressive total cave line length of 75,140 meters, it was extended to 102,901 meters and is now proudly considered the fourth longest underwater cave system in the world.
By the way, the first (Ox Bel Ha) and second (Sac Actun-Nohoch-Dos Ojos) underwater cave systems in the world are also located here on the Rivera Maya and we can dive them as well
Establishing this connection is the culmination of years of effort by cave divers worldwide. Researchers have made hundreds of dives in caves in the region and spent thousands of hours in the water. They spent hundreds more hours exploring and going through the dangerous jungle. They transported and maintained diving equipment, drove cars, and oversaw their endless repairs.
Today, the K’oox Baal is the world’s longest cave system whose entire surface, including contours and cave lines has been fully mapped.

Cenote Koi and cenote Nai Tucha (originally Tux Kapaxa, the Playground Cave)
The maximum depth is 48 ft (14.6 m).
There are several openings to the surface, with one named Cenote Koi. The main permanent guideline begins in the open water. Follow the main line, swimming for twenty minutes. Jump to your left, follow this 150 ft/ (45.7 m) shortcut, and jump back onto a main guideline. This section of the cave system has massive passageways and is highly decorated. Turn left and swim twelve minutes to an INAH-documented bone site.
Another great dive is to stay on the main line until you reach a permanent T intersection. Turn left and swim twenty minutes to the bone site. Swim straight; eight minutes later, you will reach an air dome with two shafts to the surface.
