Don't forget to go for a swim to the Cenote of Dzitnup. There are no rivers in Yucatan since the peninsula is made of limestone. Instead, there are hundreds of underground rivers, which on occasion form a small cavern with a lake inside. These caverns are often exposed to the surface through a whole or passageway. These small caverns with lakes (water wholes) are called cenotes. Since the limestone serves as an excellent filter system, the cenote water is crystalline and pure. The Cenote Dzitnup is no exception to this rule. The combined environment of a cavern, with stalactites, and the small hole allowing light to venture inside, makes this place a great swimming experience.
I spent the better half of a day swimming at the Cenote X'Keken (Cenote Dzitnup). It's a beautiful waterhole full of stalactites and more. There is a small entrance fee.
Check out the sunrays entering through the hole in the roof of the Cenote Dzitnup. It allows light to creep inside and spread colorful lights on the pleasantly cool and refreshing water.
