Hauenstein Fortification - Contemporary Witnesses on Jura Heights

From the Langenbruck-Dorf post bus stop, a narrow path initially paved leads east on the right side of the valley to Spaleneggli – with a nice fireplace – and further to Wuesthoehi. 50 m right of the crossing to Gwidem are the foundations of an artillery position, also suitable as a resting place. Over the Gwidemhoehi it goes to the south road at the foot of the Belchenflue - with emblems of the troop types involved in building this access road. The Flue itself is a well-visited viewpoint – which was "blown apart" for military use as an observation post – and offers a fantastic view over the Central Plateau to the Alps, over the Black Forest to the Vosges.

Past the historic reservoir and the niche of a telephone station, it goes over the Chilchzimmersattel to the Spitzenflueeli – the most interesting point of the hike. Here, over a length of more than 200 m, well-preserved (partly restored) trenches and troop accommodations can be visited and a large fireplace invites you to linger.

On the path over the Schattenberg pasture towards Rehhag, remains of the fortification are found again and again, as this area was covered with trenches (now mostly covered). At point 1063, approximately 80 m above the hiking trail, are remains of the Schellenberg stronghold with various trenches. Another highlight of the hike is the observation post Lauchflue, point 1072, with a small tank turret, expanded shelter – and excellent views. The path then leads us over the ridge to point 1006, where the shortest route leads over the Sennhoehi to Waldenburg. However, there is also the option of an interesting descent over the Gerstelflue, Waldenburg ruins (caution T2!) or over Humbel, Schoental back to Langenbruck. Robert Horbaty
