From Wikipedia, the free Encyclopedia: The Dolomites (Italian: Dolomiti [doloˈmiːti]),[1] also known as the Dolomite Mountains, Dolomite Alps or Dolomitic Alps, are a mountain range in northeastern Italy. They form part of the Southern Limestone Alps and extend from the River Adige in the west to the Piave Valley (Pieve di Cadore) in the east. The northern and southern borders are defined by the Puster Valley and the Sugana Valley (Italian: Valsugana). The Dolomites are in the regions of Veneto, Trentino-Alto Adige/Südtirol and Friuli-Venezia Giulia,[2] covering an area shared between the provinces of Belluno, Vicenza, Verona, Trentino, South Tyrol, Udine and Pordenone.
