The Nagelfluhkette is a mountain range located in Bavaria, Germany and Vorarlberg, Austria, bordering on the northern edge of the Allgäu Alps.
[2] The Nagelfluhkette extends throughout the western part of the Allgäu Alps west of the Illertal, in which the Bavarian cities Sonthofen and Immenstadt lie.
Between these cities is Blaichach, from where the mountain range stretches for about 20 km in west-southwest direction to the Vorarlberg community of Hittisau.
Some places, especially between Steineberg and Stuiben, and between Falken and Hochhädrich, are difficult and exposed, requiring a high degree of sure-footedness and a head for heights.
[6] Shorter routes lead, for example, from the mountain station of the Mittagbahn over the Steineberg and Stuiben through the Steigbachtal back to Immenstadt.
[7] The Königstour, an entire crossing of the Nagelfluh from Mittagberg to Hochhädrich, is doable on a single day, provided the hiker is sportive and fit (length of the tour: about 8.5 hours, including breaks).
[8] In addition to the mountain railways, there are ski lifts to the Einguntkopf (from Falkenhütte) and Hochhädrich, each on the snow-sure north side.
