Via ferrata Köllenspitze

The access is via the Gimpelhaus. From there continue in the direction of Rote Flüh until you turn right after the Gimpelalpe to the Nesselwängler Scharte. Immediately before the Scharte, turn right to the foot of the Köllenspitze south face (red dot markings, at the end in the gravel field it is better to put on your helmet).

The via ferrata itself is in difficulty level D, but also has passages with A and B. There are two rest areas but no possibility to get off.

Descent: From the summit first north on climbing tracks into a channel, then descend left (west) in the channel until you reach a steep step (rope belay; C/D). Continue down in the gully until you cross a crag on the left and ascend again through a gully. Behind the edge, descend over partly steep gravel terrain (passages 1-) to the Nesselwängler Scharte (2007 m). There again on the south side and on the access path back to the valley.

Attention: The descent is alpine! Climbing spots up to 1, partly exposed and brittle. Dangerous in snowy and wet conditions (the snow lasts quite long on the north side in spring, ask the Gimpelhaus or the Tannheimer Hütte for information about the conditions). Long via ferrata tour which should only be done in stable weather.

Complete via ferrata equipment (via ferrata set, harness, and helmet) is highly recommended even for experienced climbers!
Personal mountaineering equipment must be safe, functional, and meet the respective technical standards. Every hiker is advised to inform themselves about the planned routes in alpine specialist literature or locally.

General valid and usual behavioral rules!
It should be noted that mountaineering carries an increased risk of accidents and injuries. Despite careful route planning, a basic risk always remains. Preparing for the route through endurance training, appropriate technical training and education, as well as personal caution, reduces accident risks and dangers. But never forget that weather in the mountains can change very quickly. Stay on the marked hiking trails.

On the A7 motorway, take the "Oy-Mittelberg" exit onto the B310 towards Wertach and then Oberjoch. Follow the signs for "Tannheimer Tal" B199 and the Nesselwängle exit for the Gimpelhaus car park.
