Rangiswanger Horn (1615 m) in the Hörner group, which runs from north to south on the western side of the Illertal, is a popular winter mountain that can be hiked both from the west from the Ostertal and from the east from the Illertal . It is a classic destination with a great view of the entire Allgäu main ridge and it is considered a popular and avalanche-proof snowshoe winter hike and ski tour.

From Sonthofen we hike south west towards Sigiswang. From here we walk till the tarred road opposite the inn Knusperhäusl begins. After a few minutes we turn left at a signpost and later at another signpost right and keep us always to the signs "Kahlrückenalpe/Rangiswanger Horn". Slowly the road becomes steeper and soon we have a free View of the mountains around Sonthofen. After about an hour we reach the quite large building the Kahlrückenalpe. Over an eroded path we finally climb to the summit cross of the Rangiswanger Horn. At the top of the Rangiswanger Horn, 1,616 m, an extensive meadow peak and a magnificent panoramic view await us again, which also extends over into the western Gunzesried valley.

From the summit we have a close look at the Nagelflühkette and the Hohen Ifen. In the east, there are now also the Aggenstein, the Rote Flüh, the Gimpel and Einstein, some peaks of the Tannheim mountain celebrities.

We then hike northeast on the Hörnerpanoramaweg till we reach Ofterschwanger Horn. From here we have a view to Allgäu main ridge, Daumen group, Grünten and to all Illertal.
