The Val Grigna Regional Forest covers an area of 2,847.50 hectares, located in the municipalities of Berzo Inferiore, Bienno, Bovegno, Esine and Gianico. It extends from an altitude of 1,000 meters to the summit of Monte Crestoso, which reaches 2,207 metres. The landscape of the area is characterized by spruce fir and larch woods, interspersed with large clearings used as pastures. Much of the forest is in Valle Camonica, but a significant portion of the south-facing pastures extend beyond the watershed, into Valle Trompia.
Inside the Forest there are numerous structures, originally linked to alpine farming and cattle grazing. Over time, many of these structures have been restructured to continue to perform their function, while others have been transformed into bivouacs, refuges, agritourisms, environmental education centers and ethnographic museums. Access to the Forest and to the alpine pastures is through some forest roads, but the internal connections are mainly pedestrian, through ancient paths which today also offer considerable excursion interest. Furthermore, the area is crossed by long-distance paths, such as the Tre Valli Bresciane path and the Via dei Silter, which connect the pastures of the Vasta Valgrigna area in a fascinating trek.
Hunting is prohibited in the regional forests, but it is possible to spot deer, chamois and black grouse for those with good eyesight or a bit of luck.
