The Park develops on the northern slope of the Orobie Alps, which extend for about 50 km, from Monte Legnone to Aprica Pass, and lie between the provinces of Sondrio, Lecco, Bergamo and Brescia. 46.280 hectares, minimum altitude 850 m, maximum altitude 3052 m (Pizzo Coca), 12 areas of particular environmental value subject to special protection, 14 valleys, established in 1989: these are the numbers of Parco delle Orobie Valtellinesi, one of the largest and most significant protected areas in the region.

Little known by mass tourism, these mountains preserve the secrets of a still intact, harsh and solitary nature, which can at first intimidate. It is enough to walk along one of the numerous paths of the Park to be fascinated by the beauty of the landscape and the richness of life. To an attentive and curious eye, the spectacle of colors of this protected area will certainly not escape: the dazzling violet of a small flower, the golden yellow of the larch trees in autumn, the intense blue of the numerous alpine lakes, to the astonishment for the sighting of a small black salamander or the emotion of an encounter with the king of the peaks, the majestic ibex.
​​Parco delle Orobie Valtellinesi is characterized by remarkable reasons of naturalistic and scientific interest. The high biodiversity of its territory is evidenced by endemic species such as the sanguisorba from Valtellina and the violet Comollia and by numerous species of mosses and lichens, considered extincted in Italy and that have been recently found in the Park.
