Ski resorts at the Arlberg include Lech, Zürs, Stuben, St. Christoph, St. Anton, Oberlech, Stubenbach, Zug, and Warth.

The Valluga, which stands as the highest mountain of the Arlberg, and the Trittkopf, southwest of the Lechtal Alps, dominate the pass.

The watershed between the Rhine and the Danube rivers runs south from the Albonagrat to the Passhöhe, over the Valluga and Trittkopf, to the Flexenpass, and it traces from the Flexenspitz the southern edge of the Lechquellen mountains westward to the Klostertal.

The old pass route was known since the 14th century in the form of a narrow mule track when people began to trade salt in the region.

However, because the Arlberg was very poorly developed, for centuries people avoided the route and took detours over the Fern Pass or Immenstadt for trading.

On the Tyrolian side it is built over the Rosanna Gorge before the actual massif rises up in the direction of Vorarlberg over the tunnel.

Tourism is the main source of income for Arlberg villages and their inhabitants and plays a vital role in the region.
