Huayllay Stone Forest

Extraordinary rock formations in open Peruvian fields. 

The amazing stone formations in the Huayllay National Sanctuary known as the “Bosque de Rocas”, or “Stone Forest” were created by slow erosion and date to the Cenozoic age. Thousands of rock pillars dot the landcape. Today it is a popular destination for rock-climbers.
