Largue (rivière) - Affluent de l'Ill walks

Kilometre Zero is the starting point of the front line established during theFirst World War. It is located on the current French-Swiss border, at a place called Le Largin. The Kilometre Zero trail explores three sections of the front line, the first kilometres of the French and German fronts, and the Swiss front at Le Largin, established along the border opposite the no man's land where boundary marker No. 111, considered the zero point of the Great War front line, is located.

The landscapes you pass through here are among the most beautiful in the Sundgau region. The rock shelter of Mannlefelsen, a major Mesolithic site in Alsace, precedes the Ebourbettes, which tell the story of General Giraud's escape in 1942. Further on, the ruins of Morimont offer an interesting history lesson on how a medieval castle was adapted to firearms.

Friesen boasts an exceptional array of half-timbered houses built between 1499 and 1876. Thanks to meticulous inventory work, the walk allows you to see many reminders of a rural world that disappeared forever after the Second World War. A country lane then leads to the Notre-Dame de Grünenwald chapel and Ueberstrass, following in the footsteps of the Knights of Malta.

It is in late February and early March that you should go to meet spring in the forest of Saint-Bernard. This is where the snowdrops appear, signalling the end of winter.

The hike has been modified and no longer passes by the Ferme de la Vacherie. A lovely little walk, mostly on fairly wide paths, leading to beautiful viewpoints and sites of historical interest such as the Mannlefelsen caves and Morimont Castle. There is a slight incline on the first part of the route to add a little spice to this easy hike.

A route inviting you to explore the two neighbouring villages of Seppois-le-Bas and Seppois-le-Haut. You will also enjoy sections through the forest, including the Gobenwald.

Short, easy walk, mainly on local paths.

The village of Levoncourt is located on the D411, 12 km from Ferrette. Mont Perrou is a 767-metre-high peak in the Ajoie region of Switzerland, near the French-Swiss border.

Climb up to Roc au Corbeau, which straddles the French-Swiss border.
