Huayllay stone forest, Archaeological site in Pasco Department, Peru.
Huayllay Stone Forest is an archaeological site in Pasco Department, Peru, where volcanic rock has been shaped by wind into thousands of different forms. The rocks spread across a wide highland area and include caves with rock art as well as formations that resemble animals, people, and objects.
The cave walls carry paintings made around 10000 years ago, showing early herders living alongside llamas and alpacas. Volcanic activity in this region formed the rock before winds continued shaping it over thousands of years.
The name comes from Quechua and refers to the natural rock shapes that herders have used as landmarks for centuries. Local communities now organize festivals where visitors can try traditional dishes made with quinoa and llama, while guides lead walks past the cave paintings.
The site sits above 4000 meters, so visitors should move slowly and carry plenty of water to avoid altitude sickness. Warm clothing and sun protection are important because the weather can change quickly and the sun is strong at this elevation.
Some rock formations have names inspired by their shape, such as the elephant or the turtle, and guides enjoy showing visitors how to spot these. The stone forest is considered one of the highest of its kind in the world.
