Porrentruy walks

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.

During this fourth stage, you will walk along the banks of the Doubs to Tariche. You will cross the Doubs on a self-service boat. Then you will follow a ridge overlooking the Delémont valley and the Doubs. You will take the very pleasant Combe du Bé to reach Glovelier.

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

A superb hike in the south of the Belfort area in the foothills of the Jura. Exceptional views over the Bas Pays de Montbéliard and the southern Vosges mountains. You will also discover the charming village of Montbouton, 25 km from Belfort and 7 km from Audincourt. This hike is signposted.

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.

The walk begins at the site of Lucelle Abbey, isolated from the hustle and bustle of the world. The monastery was once a shining beacon and its history can still be seen in the few remaining buildings. From here, a Swiss getaway allows you to discover a curious rock shelter suspended above the river's source. You then climb back up to the plateau overlooking a valley enclosed between two wooded ridges and crossed by the winding waters of the Lucelle.

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.

This last stage will take you to the capital of the Franches-Montagnes district, renowned for its horse breed. On leaving Glovelier, you will cross the Combe Tabeillon nature reserve. You will pass several small lakes, including the pleasant Plain de Saigne. You will cross the village of Montfaucon, built on a ridge. You will cross pastures where many horses graze before arriving in Saignelégier.

Short excursion from Grandvillars to the remarkable lime tree

The walk leads to the heart of the Glaserberg massif, above Winkel. You will cross the Saint-Pierre State Forest to Neuneich, where you can enjoy sweeping views of the Alsatian Jura.

This second stage begins in France and rejoins the Jura trail at the Ébourbettes farm. You will walk along a border path and, at Roc au Corbeau, enjoy a view of Alsace. Until Vendlincourt, you will walk through alternating pastures and wooded areas. Before arriving in Porrentruy, you will enjoy an open-air exhibition of wooden animal sculptures. Don't miss a visit to the historic town of Porrentruy and its castle.

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.

This hike allows you to discover parts of the region's history during the Second World War, in the context of the liberation of Alsace, by following part of the Sentier des Marocains (Moroccan Trail). It also allows you to discover magnificent landscapes in the Swiss Jura, the Sundgau and the foothills of the Vosges and the Black Forest, then to follow the source of the Ill on your return to the starting point.

The peaceful village of Pleigne is located on a Jura plateau at an altitude of around 800 metres. It is the centre of a commune that stretches north to the French-Swiss border marked by the Lucelle, the river that gave its name to the lake and the small town famous for its Cistercian abbey.The route begins with the Pleigne panoramic trail and observation tower, then leaves the plateau, its pastures and farms, to descend around Lake Lucelle. Return along the river, passing close to the caves, to climb back up to the plateau through the Côte de May forest and its legendary Rocher de la Fille de Mai (Rock of the May Girl).

A walk along the water, springs and fountains in the valleys surrounding the promontory of the ancient castle of Blamont. Discover the cave of Tante Airie, the legendary Mother Christmas of the Pays de Montbéliard.

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.

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.

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.

Coming from Goumois (Switzerland), park at the end of the Vautenaivre leat, next to a small rest area (with barbecue).

Hirtzbach is well worth a visit. The castle, English park and opulent residences of Unterdorf are neatly lined up on either side of the stream, whose banks are beautifully flowered in summer. Along the way, a rural and wooded detour leads to the site of the vanished village of Sankt-Glückern and the Landfürstenweyer, the Princes' Pond, with its still waters.

A wooded hill separates the Ill and Thalbach valleys. As you walk along it, you will discover an old vineyard, a quarry marked by tragedy, a botanical trail and the story of an unfortunate general. When you reach the Emlingen lime kilns, the 19th century suddenly springs to life, frozen in stone and iron.
