Bosque de Piedras de Huayllay National Sanctuary is a remarkable protected area known for its vast expanse of natural stone formations shaped by erosion and weathering, offering unique hiking and rock climbing opportunities in the Peruvian Andes.
The Bosque de Piedras de Huayllay National Sanctuary is located in the central highlands of Peru, within the Pasco Region, at an elevation of approximately 4,300 meters (14,100 feet). This protected area spans nearly 6,600 hectares (16,300 acres) and features an extensive collection of towering rock formations carved from volcanic rock, sculpted by millions of years of wind and rain erosion. These formations, often resembling animals, human figures, and abstract shapes, create a surreal landscape that draws geologists, photographers, and adventure travelers alike. The sanctuary is situated within the high Andean puna ecosystem, characterized by sparse native grasses, ichu grasslands, and adapted wildlife such as the vizcacha, Andean fox, and a variety of bird species including the Andean condor. Historically, the region held significance for indigenous peoples who inhabited the area and incorporated local stone formations into their cultural narratives. Visitors to Huayllay can enjoy a range of outdoor activities including hiking along well-marked trails that wind through the forests of stone, rock climbing on formations like the Morocho and El Fraile, birdwatching, and camping near natural springs. The sanctuary’s unique blend of geology and ecology makes it a captivating destination for those interested in natural history and outdoor recreation. The nearby town of Huayllay serves as the primary access point and offers basic accommodations and services.
