Rupt (rivière) - Affluent de l'Allaine walks

This hike is the first of two stages linking the end of the Vosges crossing in Belfort to the start of the Grande Traversée du Jura (or GTJ on maps), located at the start of Mandeure. This hike is very cultural, starting in the historic town of Belfort. The first part takes you past three forts: Belfort, Basses Perches and Bosmont. The hike is never very far from urban areas and it is even possible to get there by TGV as the high-speed train passes through. It is a hike that alternates between woods, agricultural plains and villages of varying sizes, including Bourogne and its charming wash houses. The end of the hike is the most pleasant part of the route, crossing the dry grasslands of Bourogne and walking along the Rhône-Rhine Canal.

This hike is the first stage of the GRP® - Randonnée des Forts. Starting from Belfort, this long hike takes in two of them, the Citadel of Belfort and the Fort of Giromagny. There are also numerous ponds and lakes, such as the Étang des Forges, the Étangs Lagace, the Étangs de la Charbonnière, the Étang d'Amont, the Étang d'Avau and those in the Malsaucy Nature Reserve. The first part, from Belfort to Fort de Giromagny, is mainly forest. After the fort, the hike becomes even more enjoyable with landscapes interspersed with numerous lakes, the last of which, Lac du Malsaucy, gave its name to the nature reserve of the same name. Of course, don't hesitate to stay longer in Belfort to admire the historical monuments.

This stage is the first stage of the Grande Traversée du Jura (or GTJ). It is the easiest. It can be done in a morning and can be combined with the next stage, which goes to Saint-Hippolyte. Most of the route is through forest. The starting point is in Mandeure. A detour to the Gallo-Roman theatre allows you to start with a touch of history. After an hour's walk, the stage passes near the Mandeure viewpoint before continuing through the forest. There are a few open spaces, but they are rare. The descent to Pont-de-Roide is then short and quick.

This is the last stage before the start of the Grande Traversée du Jura. The hike is mainly through forest, crossing the woods of Sochaux, Fays and Goutils. At the end of the stage, you can explore the village of Thulay. Halfway along the route, there are shops where you can buy supplies in Seloncourt. There are also some interesting viewpoints along the way.
