A wide parn of the regional park consists in woodland (mainly beechwoods and woods of silver fir and European larch), whose development was favored by the monks of the Certosa of Pesio.

The peculiar climate of the area, which shows bot Alpine and Mediterranean features, as well as its Karstic geology, sustain a very remarkable vegetal biodiversity.

In the protected area indeed have been recorded about 1,500 different plant species; among them are quite remarkable Saxifraga cernua, Viola pinnata and the nowadays extremely rare Cypripedium calceolus.

[8] A well developed network of waymarked footpaths is available within the park, that is also crossed by the southernmost part of the GTA, a long-distance hiking trail which runs on the piedmontese Alps.
