It is the largest cave in all of America and the fourth largest in the world. It is a breathtaking spectacle due to its immensity and beauty, dominated by the color gray.

It is located in the Sierra Negra, in the southern part of the state of Puebla, so you need to leave Tehuacán and reach the town of Cruztitla.

Thanks to water seepage over millions of years, these spectacular chambers have been created. Specifically, the Ugly Doll Room measures 400 meters long by 240 meters wide and has an awe-inspiring height of 225 meters. It is estimated that six Azteca Stadiums could fit inside this cave.

If you want to explore this spectacular place, you need to be in very good physical condition and enter as a group accompanied by a specialized guide.
