The Calcehtok caverns also known as "Aktun Spukil", are considered along with the Lol-tun caverns, among the biggest in the Yucatan Peninsula and have a very complicated tunnels system. The meaning of this word derives from the mayan "cal" (neck), "ceh" (deer) and "tok" (flint). It got this name in 1875 when a sculpted stone with the form of a deer was discovered in an open well of the area that lead into it.
The main access to the entrance is a 3 Km. pavimented road, the descent is made on an iron ladder. Once into the main chamber, four different tours can be made, the most interesting has 2 Km. of galleries; natural formations called "the crocodrile", "the horse", "the tongue", "the mommy", and "the divine face" can be seen in this largest gallerie called cave #4.

Abundance of pre-hispanic materials is found in all the cavern; intact vessels, and unexplored chambers are still waiting to be discovered to add more knowledge of the Mayan culture. Arqueologists have found bones of deer and from other animals, ceramics, quartzite hammers, arrowheads, human graves, etc. some vessels that were used by the mayans to collect the filtered water of the ceilings are completely petrified. Into the first two chambers one can watch a kind of small fences as stockades that the mayan rebels used during the "Guerra de Castas" rebelion.
It is not advisible to get into these caverns alone, you may ask the help of the "Cuy family" that offer an expertise touring service into the caves, they live downtown the village.
A big complex of more than 30 caves suspected to be communicated exists in the sourroundigs, caution is recommended.
