Cenote Bolonchohol, "nine mouse holes", is located 47 kilometers to the southeast of Merida and about 5 kilometers west of Cenote Chacsinicchee. It is named for the nine entrance holes in the ceiling of this cave. The cave is entered by climbing down a ladder made from old narrow gauge train rails. One enters a 15 m diameter underground chamber at water level with ceiling heights to 12 m. A large, crystal-clear lake filled with cobalt-blue water covers the bottom of this beautiful underground chamber. When the sun light is shining through any of the holes in the ceiling, it creates a spectacular and colorful sight. Descending along the slope of the breakdown that forms a little island in the middle of the lake, the diver finds a passage at 26 m depth followed by a restriction in the floor. From this point, the cave opens onto a lower chamber that is about 20 m long and 8 m wide with a height of 2-4 m and a maximum depth of 36 m. This little cave system is believed to be fully explored.
