After attending the Project Worldschool Summit this past April, we were able to visit some amazing cenotes in Mexico. The three cenotes of Cuzuma were a short Collectivo ride from our airbnb house in central Merida. They were truly amazing.
Hopefully we can swim in a few of these stunning ones as we continue to venture around this planet.
