The Lagorai mountain group is one of the least known area's of Dolomite's. The Lagorai range is a mountain group in Eastern Trentino (Trento Province), and it represents one of the most natural areas of the province, including some of the most extensive stretches of relative wilderness in the south-eastern Alps. Its name has its roots in the word ‘lago’ ('lake' in Italian); in fact, numerous lakes of various dimensions that can be found at different altitudes within this vast mountain chain.
The Lagorai range extends over a vast area between Monte Calisio (east of Trento) and Passo Rolle (1,984 m; in the Primiero sub-region), for an overall length of about 70 km. Many valleys come down from this extensive range, some of the more important are the Primiero to the south-east and the Val Vanoi to the south, as well as the smaller tributary valleys of Val Campelle and Val Calamento (side valleys of the main Valsugana), the Val Cismon lies to the east, while the Valle dei Mocheni and the Pinè plateau are to the west. The Cembra valley lies to the north-west and the Val di Fiemme and Val Travignolo are to the north: all these valleys and regions mark the exact geographic limits of the range.
