The Hauenstein fortification was one of the most important Swiss defense structures of the first world war. It used the natural terrain of the Jura ridges and several bridge heads along the Aare river to defend the important infrastructural center of Olten. This route will take you along many of the key points of these fortifications, while at the same time showing the spectacular landscape.

The tour features: 

  • A magnificent view on the Jura and Aare valley region
  • Historic places from the first world war era (such as Chilchzimmersattel, Trimbach, Olten, Boningen, Kappel, Hägendorf, Allerheiligenberg)
  • Varied landscapes (pastures, deciduous and pine forests, river, villages)
  • Mostly small roads with little car traffic
  • Many panoramic views, with matching climbs

Almost all roads on the route are paved, most but not all are well maintained. I would recommend to cycle the tour clockwise.

Safety information

  • given the narrow roads, this tour is not suitable for large (>8 persons) groups.
  • some stretches of road are under construction and are missing an asphalt top layer. Only go riding when you feel comfortable with this.
  • not all roads on the route will be kept snow-free, so it is not possible to go when there is snow

Tips and hints

  • Several facilities to eat are available underway (such as the restaurants in Langenbruck, Berghaus Oberbölchen, Bergrestaurant Kallhof, restaurants in Trimbach/ Olten/ Aarburg/ Hägendorf)
  • A number of public water tap points can be found along the route, so no need to bring lots of water. (weather permitting, as these tap points are switched off in winter)

Destination

Langenbruck / Olten

Turn-by-turn directions

The route can be started from 2 different points, depending on your means of transportation.

  • With public transport: Olten main station
  • With a car: Langenbruck village

The disadvantage starting from Olten is that there will be just one long ascent, instead of the 2 ascents when you start from Langenbruck. It is advisable to take a break in Langenbruck when starting from Olten.

(Starting point Langenbruck) Ascend from the self-proclaimed sports- and hiking paradise Langenbruck towards the Chilchzimmersattel mountain pass, passing the Schöntal monastry along the way.

From there, shortly descend and then keep right at the small forest road. Careful: some stretches of the road are in bad shape. At the T-junction, turn right and shortly climb over the Challhöchi where some defense structures (from the second world war) can be seen. Descend through the Ifenthal village until reaching the N2.

Descend further over the N2 until passing under the train tracks. Then go left into the Rebbergstrasse. After some zigzagging through the village, take the Mühlestrasse bike road and follow until reaching the Aare river.

(Starting point Olten) Head south for a couple of kilometers, all the time keeping the river on the left side, passing Olten train station just across the river. South of Olten, a short detour around the local swimming pool is required. In Aarburg, the road joins with the N8. Follow this road until in Boningen and take a right turn after the large Hofladen. Pass under the highway until reaching Kappel.

Follow through the village center until in Hägendorf, from where another long ascent starts. The Allerheiligenstrasse takes us up alongside the Teufelsschlucht. Keep following directions towards Langenbruck at each junction. After some more climbing, we reach the beautiful Bärenwil village, from where we can calmly descend back to Langenbruck.
