Ik Kil, located in the northern center of the Yucatán Peninsula, Mexico, is a deep natural sink hole open to the sky, that formed by the collapse of a cave. With vines and ferns extending downward into the sinkhole it is a place of unbelievable natural beauty. Also, there is a carved stairway down to a swimming platform. Cenote Ik Kil was considered sacred by the Mayans who used the site as a location for human sacrifice to their rain god.
