We visited Ik Kil after a tour of Chichen Itza. If you have the option to do this (sometimes your tour will offer the stop), go for it! It was one of the highlights of our entire trip. A pleasant cool freshwater swim after sweating like crazy and climbing around the dusty ruins was perfect.

You decend to the cenote by a rock staircase. There are a few fish in the water and a small shower of water decends to the pool from the roof of the cave. Ik-Kil Eco-archaeological Park is located 5 kilometers from Chichen Itza along Highway 180. Check their web site for more specific directions.
