The sinkhole or cenote is a natural feature found all over the limestone-rich Yucatan peninsula.These sinkholes are created when the limestone on the surface collapses to reveal the underground river system below.Many cenotes or sinkholes are open to the public for swimming, snorkelling or scuba diving.They are located on the aptly named Cenote Route close to Puerto Morelos, 30 minutes away from Cancun by car.One of the most beautiful cenotes, Ik Kil, is well worth a visit and can be found next to the world wonder of Chichen Itza, easily combined into a memorable day trip.
