1.Cenote Ik Kil,Yucatan,Mexico
Cenote Ik Kil Formed by the collapse of limestone bedrock, Cenotes are natural swimming holes that had particular significance to the Mayan communities in Mexico’s Yucatan Peninsula. Thought to be sacred wells, the Mayans believed they were a portal to speaking with the gods.
Cenote Ik-Kil, unlike many other cenotes, is open to the sky and the sunlight turns the water a bright teal colour with vines hanging down around it. For 70 pesos ($A5), visitors can access the cenote by walking down a set of stairs to the bottom where they can swim in the sacred waters.
