About Parque Nacional Bosques Petrificados

Parque Nacional Bosques Petrificados is a unique protected area in Argentine Patagonia, celebrated for its vast fossilized forests dating back over 65 million years, offering a fascinating glimpse into prehistoric ecosystems alongside striking Patagonian landscapes.

Wilderness Landscape & Natural Heritage

Parque Nacional Bosques Petrificados is located in the province of Chubut in southern Argentina. Spanning an area of approximately 248,000 acres (100,000 hectares), this national park preserves the world’s largest known deposit of petrified wood. The park’s landscape is characterized by arid Patagonian steppe interspersed with ancient fossilized trees that have turned to stone through natural processes over millions of years, mainly dating to the late Paleocene epoch. These extraordinary fossilized forests represent an invaluable natural and geological heritage, providing insight into prehistoric flora that once thrived in the region. The park lies near the town of Sarmiento and is accessible via national routes, making it a significant destination for both scientists and outdoor enthusiasts. Visitors can explore several trails that wind through extensive fossil sites, admire colorful petrified logs, and visit interpretive centers that explain the geological and biological history of the area. Wildlife in the park includes guanacos, Patagonian foxes, and numerous bird species adapted to the steppe environment. The park’s vastness and unique terrain afford opportunities for hiking, birdwatching, and photography, particularly focused on the dramatic landscapes and fossil formations. The dry climate and solitude make it a compelling destination for those interested in paleontology, natural history, and remote outdoor experiences. Despite its arid nature, the park offers a rich educational experience complemented by scenic vistas and a chance to connect with the prehistoric past. Visitors are encouraged to prepare for the park’s dry and often windy conditions while exploring its extensive petrified forest trails and lookout points.
