The Cacahuamilpa Caves is one of the largest systems of caves on earth and is “live,” meaning that groundwater is actively filtered through the system, and the formations inside the caverns are still growing. There are ninety large areas within the caves that natural rock walls divide, and twenty of them can be explored by visitors at Grutas de Cacahuamilpa National Park. These caves are found under a limestone mountain ridge called Cerro de la Corona.

One of the salons inside the caves is called “the auditorium,” and seats have been installed so that space can be rented out. Concerts and other special events have been held inside. Tours of the cave systems are offered on the hour and last for tour hours. Cacahuamilpa Caves Map
