Covering an area of about 68,898 hectares, the park includes the northern part of Bergamo side of the Orobie series, whose height varies between 2000 m and 3000 m at an altitude.
This protected area is characterized by valleys that heavily affect the land and whose waters are fed by the main rivers of Bergamo, a "mountain forest park".
The territory of the park is divided into two distinct geographical areas, the northern part and the southern part. The first, called the Tropical Ridge, represents the border with Valtellina and a European Valtellini park in the north with dark continental or crystalline rocks and sediments. The highest peak is Pizzo Coca (3050 m), followed by Pizzo Redorta (3038 m) and Punta de Scais (3038 m).
The southern part, on the other hand, consists of isolated mountain groups, which form the Orobie Pre-Alps Mountains, which consist of clear rocks, above all dolomite and limestone, from marine extraction. The highest peaks are Aralalta, Cancervo, Arera, Presolana, Ferrante, and Alben.
The last glacier on the banks of the Bergamasco River from Orobie is the Trobio Glacier, located at the foot of the ridge linking Monte Gleno to Pizzo di Tre Convini. Other glaciers remaining to date have been found on Valentine's side of the Orobie region, such as the Marovin River and the Glaciers in the Scais, but they are also in rapid disintegration.
A special feature of the park is the wealth of water and the alpine lakes, about a hundred, and above all between the valleys of Syriana and Primbana, which have already been exploited to produce electricity from the beginning of the twentieth century. The numerous valleys are flooded with streams and streams that feed the three dominant rivers: Brembo, Cerio and Dizo. Equally, but also of great ecological, economic and tourist significance, there are waterfalls, including the Serio Falls in Valbondione, the highest in Italy and the second in Europe with a triple jump of 315 but designated as a legend (waterfall legend), the walls of Val Sambuza in Karuna The charming waterfalls of the Vu River in the Val di Scalf.
Within the park area there are eight sites of community interest (SIC).
