Morphologically the region can be subdivided into four main areas. The mountainous area in the north: this part of the region includes Carnia and the ending section of the Alps (Carnic Alps and Julian Alps), of which the highest peaks exceed 2,700 m above sea level (Jôf di Montasio 2,754 m). Its landscapes are characterised by vast pine forests and pastures, mountain lakes (e.g. Sauris, Fusine and Barcis) and numerous streams and small rivers descending from the mountains.
