The Silvretta Alps are a mountain range of the Central Eastern Alps shared by Tirol, Vorarlberg (both in Austria) and Graubünden (Switzerland). The Austrian states of Tirol and Vorarlberg are connected by a pass road (Silvretta Hochalpenstraße at 2032 m). The majority of the peaks are elevated above three thousand metres and are surrounded by glaciers. Thus, the area is also known as the "Blue Silvretta".
