The legend says that a long time ago this place was populated with modest people. The Devil decided to make something about that. He prepared a water which made them forget about their past. The people drank it and prepared a wedding between brother and sister. But God prevented that wedding to happen. He turned all the locals into stones. Now we have 202 rocky pyramids with a height of 15m and two springs with high mineralization and acid water. A real natural wonder!
