Established in 1980 by the Piedmont Region, it protects 3280 hectares, occupying the head of the catchment basin of the Chisone stream, whose sources originate from the Barifreddo and Appenna Mountains. Much of its perimeter is delimited by peaks that exceed three thousand meters up to 3280 of Rognosa del Sestriere, the highest mountain in Val Chisone. Since 2012 it has been part of the system of protected areas of the Cottian Alps together with the Natural Parks of the Avigliana Lakes, Orsiera Rocciavré, Gran Bosco di Salbertrand and the Chianocco and Foresto Nature Reserves.
The protected area lies entirely within the municipality of Pragelato, of which it incorporates 89% of the territory. It represents a treasure chest of biodiversity on the border of the international ski area of the Milky Way. It collaborates closely with the Municipality of Pragelato to encourage respect for natural balances and promote sustainable fruition activities.
The Park territory is now recognized within the Natura 2000 Network based on the European Habitats and Birds Directives. The Park headquarters is a few kilometers from the protected area and is located in the town of Pragelato, in the hamlet of La Ruà. It houses the park's visitor center and museum dedicated to the main naturalistic and historical aspects of the area.
