Monumento natural Bosques Petrificados

The park contains massive fossilized tree trunks scattered across 78,543 hectares of protected Patagonian terrain, displaying different stages of mineralization and preservation.

The site originated 150 million years ago during the Jurassic period when dense forests with giant trees flourished before volcanic activity caused their mineralization.

Scientists and researchers examine these petrified remains to understand the environmental changes that occurred in Patagonia before the formation of the Andes mountains.

Visitors need to arrange transportation suitable for unpaved roads and bring supplies, as the remote location offers minimal facilities in the surrounding area.

The preserved tree specimens include ancient Araucaria mirabilis specimens that reached heights of 100 meters with trunks measuring 3.5 meters in diameter.
