The Hoher Ifen is a 2,230 metre high mountain in the Allgäu Alps, west of the Kleinwalsertal valley. In winter it forms the backdrop for a small ski area. It lies on the border between Germany and Austria. The summit is the highest point on the gently, tilted Ifen plateau. Northeast of the Ifen plateau is the Gottesacker plateau, a karst landscape which has been designated a nature reserve and which has numerous caves and rare mountain plants.
