Pfetterhouse walks

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.

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

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.

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.

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.

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.

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.

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.

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).

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.

Short excursion from Grandvillars to the remarkable lime tree

This family hike takes you to the majestic Gros Chêne de Sondersdorf. Entirely in the forest, it passes through the Raedersdorf Discovery Trail, decorated with around fifty (or more) wooden sculptures and dotted with educational panels that are sure to interest children. Best done in dry weather in any season.If you only want to do the discovery trail and see the sculptures, see Practical Information.

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.

A superb hike on the border between Belfort and Haut Rhin. You will discover a landscape of countryside and forests with magnificent ponds. As a bonus, there is a discovery trail with information panels about the trees of our region.

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.

The fighting of the First World War raged in the Sundgau region from August 1914 onwards. The French blew up the Dannemarie viaduct and the front stabilised and extended from the Vosges to the Swiss border. The front line ran a few kilometres from Illfurth, near Heidwiller. During this tour, you will discover several bunkers that served a variety of purposes, including ammunition depots, observation posts and artillery emplacements, as well as several casemates.

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.
