Declared a national historic site in 1931, the site is notable for its cultural and natural heritage. The park's territory is mainly three distinct natural areas: the plateau, the escarpments and the lowlands. Overall, over 80% of the total area of the park is a wooded area with approximately 20 different stands and a number of plants from the climatic forest type of the Laurentian maple stand and the Upper St. Lawrence forest sub-region. Of particular interest is a forest of cedar trunks so twisted that it was nicknamed the "Enchanted Forest". Of the fort itself not much remained, but a modern visitor's centre, exhibits, and reenactments highlight the cultural history of the place.
