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.

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.

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.

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.

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.

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.

A beautiful hike to discover Ferrette, a beautiful medieval town with its castle and the Grotte des Nains (Dwarves' Cave) with its famous legend known to everyone in Alsace.

This short hike will take you to the Roman Theatre and the Mathay plain via a path with views over the Doubs and all the biodiversity associated with this coastline: dry and wet forests, cliffs, scree and ponds are home to many protected species. Play areas, picnic areas and facilities are dotted along the route.

This first stage of the Chemin du Jura begins in Delémont, the capital of the Canton of Jura. You will cross this pretty medieval town. A forest path will take you to a plateau offering a view of the Jura mountain range. Before descending to Lake Lucelle, you can enjoy another panoramic view at the Grande Roche. The village of Lucelle in Switzerland no longer has any accommodation, so you will make a short detour into Alsace, to the commune of Lucelle in France, where you can stay at the Auberge du Petit Kolhberg.

A pleasant route for exploring the canton of Jura. This five-day itinerary will take you through the canton's three districts: Delémont, Porrentruy and the Franches Montagnes.

A picnic area with tables overlooks the Dessoubre valley at an altitude of nearly 750 metres. Old farms dating back to the 1960s cling to the mountainside. A wild valley where, perhaps, our Comtois Gauls performed their druidic rituals in sacred clearings. A natural rock known as the Devil's Castle overlooks the Waroly waterfall. Finally, caves carved out over centuries.

The ladders will probably be closed until autumn. There are no danger points on these ladders. This historic site bears witness to the fear once inspired by these legendary places, the scene of many fatal accidents during the "bricotte" smuggling era, when the ladders were nothing more than tree trunks crossed by pieces of wood. Today, these comfortable family staircases, which you can climb safely, allow you to discover the Doubs Gorges from a number of viewpoints.

Beautiful views, a lovely setting and an unusual part of the hike, crossing the death ladders.
