Is the road to Schlüsseljoch unpaved?
Yes, the road to the summit is entirely unpaved. This is an old military route built for strategic purposes, characterized by its narrow path and very damaged surface. The track is extremely rough, featuring steep sections and several sharp hairpin turns as it approaches the summit. While historically a road for military vehicles, today it is a very challenging route where a high-clearance 4x4 vehicle is essential if motorized access is permitted.
How long is the road through Schlüsseljoch?
The total distance of the pass is 14.1 km (8.76 miles). The route runs west-to-east, starting from the SP508 Road near the village of Borgone (Burgum) and ending at the SS12 Road in Terme di Brennero (Brennerbad). The elevation change and the technicality of the terrain make it a slow and demanding journey.
Is Schlüsseljoch open to vehicles?
This is a critical point for travelers: many high mountain tracks in South Tyrol are now restricted or closed to unauthorized motor vehicles. Before attempting the drive, it is vital to check local regulations in the Sterzing/Vipiteno area. If closed to cars, the Schlüsseljoch remains a legendary and grueling route for mountain bikers and hikers.
Is the pass open in winter?
Set high in the Zillertal Alps, the pass is typically buried under snow from late October until June. The road is not maintained in winter, making it completely impassable for vehicles during the snowy season.
