Huayllay National Sanctuary
Pasco
Huayllay National Sanctuary, located in the Pasco region of Peru, is renowned for its spectacular rock forest formed by volcanic ignimbrite shaped through millennia of erosion. These formations, often compared to China's Shilin Stone Forest and the US Garden of the Gods, create a surreal landscape of natural sculptures resembling animals, humans, and other shapes. The sanctuary spans 6,815 hectares within the Meseta of Bombón plateau at altitudes between 4,100 and 4,600 meters above sea level. It preserves a cold, dry climate ecosystem with native plants including the rare queñual tree (Polylepis sp.) and fauna such as vicuñas, vizcachas, and Andean wild cats. Visitors can explore hiking trails and rock climbing routes amid this unique geological and ecological sanctuary. Additionally, a natural thermal spring with temperatures exceeding 60°C is found within the rock forest, adding to the area's allure. The sanctuary was established to protect these geological formations alongside its native flora and fauna, providing a rare glimpse into volcanic landscapes sculpted by natural forces over thousands of years.

Historia
Huayllay National Sanctuary was officially established on August 7, 1974, to protect its remarkable volcanic rock formations and native ecosystems.
The rock forest itself dates back to the early Cenozoic era, formed by volcanic ash deposits creating a plateau.
Around 20,000 years ago, glacial cycles of freezing and thawing caused intense erosion, sculpting the unique rock shapes seen today.
Over centuries, the sanctuary has become a protected area preserving both geological heritage and the native flora and fauna of the high Andean puna ecosystem.
