Flexen Pass is a high mountain pass at an elevation of 1,773 m (5,817 ft) above the sea level, located in the Austrian Alps in the Bundesland of Vorarlberg.
The road over the pass is asphalted. It’s usually open all year long and connects the upper Lech River valley between Warth, Lech, and Zürs with the Klostertal near Stuben.
On the summit there is a a parking lot and a small snack bar. The pass road was built in 1940 and leads to the road over the Arlberg pass. Some hundred meters behind the pass summit the road disappears in a very old avalanche tunnel, which covers the road almost the rest of the distance to the Arlberg pass exit. The road in that avalanche tunnel is in awful condition and the ceiling of the tunnel is made out of old oak wood. The traffic is single-lane and is managed with a traffic light system. Approximately 500m behind the end of the avalanche tunnel, you reach the exit to the Arlberg pass road.
