Iseler, Mountain peak in Allgäu Alps, Bavaria, Germany

Iseler is a 1,876-metre subpeak of the Kühgundkopf in the Allgäu Alps, rising above Oberjoch and Bad Hindelang. Its summit is bare grey Hauptdolomit rock, with long pale scree gullies running down the eastern face and dark green vegetation in bands across the lower slopes. A six-seat chairlift, the Iselerbahn, runs from Oberjoch up to 1,580 metres.

The Iseler is a secondary summit of the Kühgundkopf, forming the northern end of the Rauhhorn ridge above Oberjoch and Bad Hindelang. Until a few years ago a single-seat chairlift led up the mountain; it was rebuilt as a six-seat chairlift, and in winter the slopes serve as a ski area. In July 2008 a via ferrata was opened above the lift's top station, leading to the summit and on to the Kühgundkopf; it was long called the Salewa-Klettersteig and has borne the name Edelrid-Klettersteig since 2021.

The mountain paths near Iseler connect traditional Bavarian villages where regional festivals and mountain traditions continue throughout different seasons.

The ascent is possible from several starting points, with the upper chairlift station offering a higher entry point. The trails are marked and vary in difficulty, so both beginners and experienced hikers can find suitable options.

Above the Iselerbahn top station, a via ferrata opened in July 2008 leads to the summit and on to the Kühgundkopf. Its first section runs 800 metres, with the key passage at the Bergführerplatte rated C; the second section crosses the Schusterplatte, also around C. It is closed from November to June for nature conservation, and since 2021 it has been named the Edelrid-Klettersteig after the outdoor firm that sponsors it.
