System 4: Dolomiti Friulane / Dolomites Furlanis e d'oltre Piave

The overall surface area is 470 km2 (of which 398 in the Province di Udine and Pordenone and 72 in that of Belluno) and it is enclosed between the Piave, the upper Tagliamento, the Val Tramontina and the intermediate part of the Val Cellina.
From the hydrographical point of view the nucleus of the area is constituted by the head of the Cellina Torrent with its two affluents Cimoliana and Settimana. The northern part refers to small affluents on the hydrographic right hand side of the Tagliamento and to the west, the Piave River. The main groups from north to south are the Cridola (2581 m), Monfalconi (Cima Monfalcon 2548 m), the Spalti di Toro (Cadin di Toro 2386 m) and Duranno-Cima Preti (2706 m).
