Grotte du Château de la Roche walks

This hike is the second stage of the Grande Traversée du Jura. Although a little longer and more difficult than the first, it is one of the easiest stages of this crossing. Starting from Pont-de-Roide, the hike begins with an ascent to the Tour Carrée, passing by the Fort des Roches, which offers a superb view of the region. The hike then alternates between meadows and wooded areas, touching on the theme of the Second World War, notably with the Passage de la Douleur. The descent to Saint-Hippolyte is pleasant, with stops at Chamesol and the Chapelle Notre-Dame du Mont. Of course, once you arrive, don't hesitate to take a longer break in the beautiful village of Saint-Hippolyte.

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.

During this third stage, you will cross the historic town of Porrentruy. As you leave the town, the path runs along the edge of the woods before starting the climb to the Chalet des Chainions (Chalet des Amis de la Nature). The route then continues along a ridge before descending towards the hamlet of Seleute. As you approach Saint-Ursanne, you can admire the Clos du Doubs and its rocky massifs. You will enter the historic town of Saint-Ursanne through the Porte Saint-Paul.
