Ik Kil Cenote, (some refer to it as ikil cenote) is a deep natural pit usually open to the sky (formed by the collapsing of a cave), Mexico has a special name for those kind of places: “cenote” -taken from Mayan language word for a well. some Cenotes were a sacred, Young men and women were thrown and left to drown there,as a sacrifice to the god of rain).
Ik Kil cenote is a popular stop on the way to the ancient Mayan city of Chichen Itza (specifically popular among bus tours, since there is a restaurant and store on The Premises) the Cenote is about 25 meters beneath the surface, The stairway is beautifully lit up & carved into limestone rock and reaches the swimming platform, usually crowded with swimmers, the pool itself is about 60 meters in diameter, the water are very deep around 35 meters. There are vines descending from the top and little water drops constantly flow from above. There are some black catfish which live on the pool, not to worry they don’t bite.
in 2010 & 2011 there was a crazy Red Bull Diving Competition (scroll all the way to the end of the post to see the video) the divers jumped into the cool water from a platform placed all the way above the Cenote.
