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.

Speaking of this part of the Sundgau, André Gide wrote:"One is constantly surprised, as one crosses the forest, to find oneself in the presence of an unsuspected sheet of water, mysteriously asleep in the shelter of the beech forests; rushes adorn narrow sandy beaches at the edge of large fields of water lilies. There are also several reminders of the First World War and the front line that separated Largitzen from Bisel.

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.

This family hike takes you to the majestic Gros Chêne de Sondersdorf.

The Raemel mountain range, two kilometres long, blocks the horizon and rises to an altitude of 832 metres. It is the highest point in the Alsatian Jura, accessible via a picturesque limestone ridge, the Sentier des douaniers or smugglers' path, which follows the French-Swiss border. This is a fairly challenging walk, but it offers magnificent views of the Swiss Jura.

Starting from Les Blanches-Fontaines south of Undervelier (Canton of Jura), this hike offers a magnificent ascent of the Sorne river and its gorges dotted with several waterfalls, passing by Lac Vert, all in a wild environment, to the hamlet of Pichoux, then climbing up to the plateau overlooking the gorges to enjoy a magnificent view. Continue along the plateau via Rebévelier, then a moderately pleasant descent down the Côte de Tirmenté to the Combe des Beusses. Return to the lush vegetation at the bottom of the valley via the Combe es Monin (home to a private foundation dedicated to children), then a short climb to Blanche Maison with another beautiful view of the landscape and a hilly descent passing above the Pré de Joux, then through several pastures towards Undervelier. Short link along the road, climbing up the Sorne to the start.

Along this trail of bunkers, explore fortifications dating back to the First World War, built by the German army. After the fighting in the summer and autumn of 1914, the Haute-Alsace front stabilised on along the line of Cernay-Dannemarie. The commune of Burnhaupt-le-Bas remains on the German side. In December 1914 and January 1915, the French offensive in this sector regularly broke the German lines at the cost of many lives.

From the castle ruins, you will climb up to the ledges where, like tightrope walkers from one border marker to the next, you will walk along the ridge line, neither in France nor in Switzerland. You will reach the Réclère Caves, considered the most beautiful in the world by the first explorers in 1886. From Journey to the Centre of the Earth by Jules Verne to Conan Doyle's The Lost World, you will squeeze between dinosaur feet. The return journey, via the old farmhouse at Montavon, will be less adventurous.

Before the construction of the Canal of Alsace (1928), the Rhine extended its arms east of the Huningue Canal (1806) over a wide area of 1km to 2km. From the Rhone Canal on the North Rhine to the Barre d'Istein on the Old Rhine, along paths and trails often in the protected areas of the "Little Alsatian Camargue.", you'll discover numerous natural and industrial sites related to the history of the Rhine. Begin with a stroll between the drawbridge of Kembs (1831) and l'Ecluse Le Corbusier (1961).

This beautiful hike takes you from Masevaux to the summit of Rossberg at an altitude of 1,191 metres. From the top, you can enjoy magnificent views of the Vosges, the Alsace plain, the Black Forest, the Jura and the Alps. The elevation gain is significant, but the route is otherwise easy.

This hike will take you to the Source de la Doller, which, contrary to what you might think, does not originate at the Ballon d'Alsace, but below the Schlumpf.
