Pampachiri Stone Forest

The Pampachiri Stone Forest in Andahuaylas is one of the most singular and breathtaking landscapes in Peru. Located in the Andes of the Apurímac region, at an altitude of 3,600 meters above sea level, it covers an area of approximately 60 hectares and features rock formations of extraordinary shapes that seem to belong to another world.

The cone-shaped formations, some reaching up to 10 meters in height, create a fantastical landscape sculpted by wind and rain over millions of years, giving them varied profiles that stir the imagination: some resemble giant mushrooms, others look like medieval towers or petrified human figures.

Geological Origin of the Formations

The rocks of the Pampachiri Stone Forest formed approximately 4 million years ago from material ejected by the volcanoes Qarwarasu and Sotaya in the form of pyroclastics (consolidated ash and volcanic material). Over time, erosion agents — primarily wind, rain, and temperature changes — carved into these volcanic rock masses, wearing away the softer material and leaving the harder zones standing as the columns and towers we see today.

The site is characterized by numerous pointed or mushroom-shaped rocks, 6 to 8 meters tall, containing minerals such as quartz. These rocks have a particular consistency: they are hard but brittle, and in sunlight or at certain times of day they take on reddish, ochre, and grey tones that create a unique visual spectacle.

What to See and Do in the Forest

Exploring the forest: the site has marked trails that allow close exploration of the formations. The most striking aspect is the variety of shapes — no two rocks are alike, and every angle offers a different perspective. It is worth taking your time, pausing to observe the details, and taking advantage of the stunning contrasts between the rocks and the Andean sky.

Roqrosqa Lagoon: about an hour and a half’s hike from the forest lies the Roqrosqa Lagoon, a high-altitude Andean lake whose calm waters reflect the skies of Apurímac. The trek to reach it combines the rocky formations with the Andean puna and its typical ichu grasses, adding an extra dimension to the visit.

Pampachiri Waterfalls: a short distance from the forest, the Pampachiri Waterfalls can also be visited — a cascade that descends among the volcanic rocks, forming natural pools.

Pacucha Lagoon: at 3,125 meters above sea level and a few kilometers from the forest, the beautiful Blue Lagoon of Pacucha offers one of the largest bodies of water in Apurímac, surrounded by totora reeds and rich birdlife.

Culture and Community

The Pampachiri Stone Forest is also a place of cultural significance for local communities. The Andean people of the area attribute mystical properties to the formations and incorporate them into their beliefs and traditions. Some of the rocks have names that reflect figures recognized by the community.

A visit to the site is a great opportunity to interact with the rural community of Pampachiri, purchase local handicrafts, and sample the typical gastronomy of Apurímac, which includes roasted guinea pig (cuy), corn tamales, and pork chicharrón.

Recommendations

• The altitude of 3,600 meters can affect those who are not acclimatized. It is recommended to rest for at least one day in Andahuaylas (2,920 m) beforehand.
• Bring warm clothing: although Apurímac enjoys sunny days, cold can arrive without warning.
• The best time to visit is the dry season (May to October) when the trails are clear and the skies are open.
• Bring water and snacks; there are no food vendors at the site.
