Trails and trunks
The gigantic trunks of fossilized araucarias are the most striking feature within this protected area; however, the deep canyons also hide dinosaur and marine fish fossils.
There is a 2.4 km trail (1 hour return hike) that allows visitors to see prehistoric flora and fauna remains up close, and to enjoy breathtaking views from several viewpoints along the way. You can also visit the interpretation centre, which displays paleontological and archeological remains found in the region.
