Vorarlberg is located at the western edge in Austria and is - apart from Vienna - the smallest federal state. It's spread out from the south-eastern shore of Lake Constance all the way up to the Arlberg mountain range. The highest summit is the Piz Buin in the Silvretta mountain range with a height of 3.312 meters (10866 ft). The most famous and largest ski resorts are Lech Zürs am Arlberg, Silvretta Montafon and the Kleinwalsertal. In Vorarlberg you'll find nearly 1.000 kilometers of piste (621 mi) because the resorts reach a height up to 2.400 meters (7874 ft). The resorts are known to have a relatively high snow guarantee because clouds build up in front of the alps coming from low pressure areas in the northwest. These clouds bring tons of new snow to the resorts. Warth am Arlberg is with more than eleven meters of snow (36 ft) per year the snow richest village in the entire Alps. For German visitors the resorts can be reached easiest via the A12 highway.
