La Peña de Bernal is a monolith with a height of 433 meters, one of the tallest in the world.
La Peña de Bernal is located in San Sebastián Bernal, a small town in the Mexican state of Querétaro. It is one of the most touristy places near the state capital and is considered one of the 13 Wonders of Mexico.
According to studies, the rock was formed from a volcano that exhausted its activity, later the lava inside solidified, and the erosion it underwent over the years made the remnants of the volcano disappear. The solid magma that remains is what constitutes and shapes the monolith.
