From the minimal height (m 390 near Breno) to the maximum (m 3539 of the Adamello's summit) of the Park, there are over 3000 meters of difference in level: such difference of altitude causes remarkable weather variations that, added to the several rocky underlayers and exposures, form a great variety of ecosystems and landscapes.

The vegetation changes from the thick forests of mixed broad-leaves on the side of the lower valley, to the forests of red firtree and larch, to the heath and alpine meadows at high altitude.

All the alpine fauna is present in the Park. The roe-deer and the deer are spread in clearings in the forests of mixed broad-leaves. The chamois lives in herds above the limits of the arboreal vegetation. Thanks to the recent reintroduction, the ibex is also present in the Park.

The core of the Adamello massif, made of intruding magma-rocks, is preserved as an extended plateau, surrounded by spectacular rocky walls some of which are over 3000 meters in altitude.

With an extension of over 1800 hectares, the Adamello glacier, formed by the hanging glaciers of Adamè, Salarno, Corno di Salarno, Miller Superiore, Mandrone and Pisgana is the largest glacier in Italy. The Group of the Adamello has a "star" form conformation, therefore from the large central plateau start numerous mountain chains which, in their turn, constitute the several valleys of the Park, set in a radial way and suspended in plains and terraces.

As testimony of past glaciations remain wide and suggestive moraines, used today as access ways to the legendary summit of the massif.

The ancient human presence is illustrated by the rock art engravings seen on the rocks all over Vallecamonica, particularly at Capo di Ponte, Ceto, Cimbergo, Paspardo, Sonico and Darfo Boario.

Terraces, "malghe", "baite" (alpine huts), "silter" (places used to make cheese) spread on clearings and on the mountains of the Park, are signs of Man's silent presence on the territory, maintained for centuries with respect for nature and a conscious use of its resources.
