Museum and information centre
At the entrance to the park, next to the park ranger section, there is a small museum with information about the place and the phenomenon of petrification. From here, you can already see a landscape dominated by the presence of the Madre e Hija hill and strange geological formations.
It's worth talking to the park rangers to understand the amazing changes that turned this ancient rainforest teeming with dinosaurs into today's awe-inspiring desert.
This trail begins at the park ranger section, is 2 km long and is of low difficulty. It leads to the fossilized trunks of several huge araucaria trees, which lie on the ground and can be seen up close. Some are 35 meters long and 3 meters in diameter, and at the time of petrification they were already a thousand years old. There is also a viewpoint with great views of the Madre e Hija hill.
During the walk you can see birds such as choiques, loicas and tucúqueres (Magellan owls) and some mammals such as guanacos, piches and gray foxes.
Important: the park is full of small fossils that, in the past, some visitors took as souvenirs. By leaving them in place, you help yourself to preserve it.
140 km from Bosques Petrificados de Jaramillo, in the town of Fitz Roy, is the "Ice Age" site, where in February 2007 the remains of two prehistoric mammals were found —a glyptodon and a sloth— that belong to the of ice from about 18 thousand years ago. You can see, under a glass dome, the excavation site and the replica of these animals, as well as information on how they were extracted. The place is freely accessible.
