Cenote Ik Kil

Cenote Ik Kil is a tropical cenote located in the Yucatan region of Mexico, just a few miles away from Chichen Itza. A sinkhole filled with water, Ik Kil is one of the most popular cenotes for travelers to the eastern coast of Mexico thanks to its lush surroundings and easy accessibility. Cenote Ik Kil is not partially covered by earth like many cenotes but is instead open to the sky; sunlight streams down and hits the water, making it a bright teal color, from which it gets its nickname: Sacred Blue Cenote. Vines hang down from the rock walls, and gentle waterfalls also make their way down the sides of the encompassing circular wall, which stretches up 85 feet around the surface of the water, giving the cenote a more exotic feel. 
Stairs down one side of the rock wall lead to a ledge from which you can get in the water to swim. The water stretches down 130 feet; while swimming, keep an eye out for the catfish that call the cenote home.

Practical Info

Before getting to the water, visitors must enter the Ik Kil Archeological Park, which has an admission fee of 70 pesos. There are changing rooms close to the cenote, as well as lockers available for rental and even a restaurant.
