Exploring and swimming in cenotes (natural sink holes) is an amazing experience.
The cenotes or sink holes are located near a small hamlet, half a mile from Cuzama (and about 1 hour and 15 minutes from Merida). They are located in what used to be a hemp (or sisal) plantation. The (narrow gauge) railroad tracks and the wagons you will ride on were the infrastructure that allowed to transport the hemp to the production facility at the hacienda. These wagons have been modified for passenger use; 4 visitors fit in one cart, (maybe 5/6 if small children are in your party). Each wagon is hauled by a horse across the abandoned estate.
Due to an ongoing land dispute, the regular tour has been modified. It currently it includes 2 cenotes (previously 3)
After the adventure, continue to Mayapan, the last Mayan capital of the northern lowlands. Mayapan is a small-scale version of Chichen Itza, and became the capital of the northern lowlands after the downfall of Chichen Itza. This site is off the beaten path, and thus less crowded.
If you wish to explore more cenotes, instead of going to Mayapan, have lunch at Cuzama and then you wil be driven to the 2 cenotes within the village of Homun, only 15 minutes away from Cuzamá.
