According to Marc Glotz, "The Sundgau has only two Romanesque churches, both founded by the dynasties that shared the region in the Middle Ages: the Habsburgs and the Ferrettes. While Ottmarsheim evokes Carolingian grandeur, Feldbach recalls monastic simplicity. You leave it as if returning from a pilgrimage, with a renewed sense of serenity and the impression of having encountered the fleeting shadows of the counts."

In warm weather, this is a pleasant walk from the Ill valley to the old bed of the Rhine at the foot of the Jura mountains. The well-marked path offers plenty of opportunities to rest and leads to a strange crypt, the last vestige of a convent destroyed during the Revolution, where the shadow of an exiled poet still lingers.

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.

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.

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.

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.

This is an opportunity to visit the ruined castle and the town of the powerful Counts of Ferrette. Narrow, romantic paths lead to stunning limestone promontories and the mysterious Grotte des Nains (Dwarves' Cave), which is the subject of a famous legend.

For geologists, this part of the Sundgau facing the Porte de Bourgogne is called the Fossé de Dannemarie. The landscape is gently undulating, with only one wooded hill emerging. At its summit stands the church of Gildwiller, where gazes and prayers converge.

Below the Hochistross, the high road from Altkirch to Basel, villages dot the Thalbach valley. The old grain mill in Hundsbach has recently been restored, much to the delight of artists and history lovers.

The Raemel mountain range, two kilometres long, blocks the horizon and rises to an altitude of 832 metres. It is the highest point in the Alsatian Jura, accessible via a picturesque limestone ridge, the Sentier des douaniers or smugglers' path, which follows the French-Swiss border. This is a fairly challenging walk, but it offers magnificent views of the Swiss Jura.

The Eptingen family, who had already settled on the edge of the Sundgau region in the 14th century, owned both Hagenthal and Neuwiller, where they lived in comfortable castles. This walk crosses their former seigneury and passes through a one-kilometre-wide bottleneck between the borders, as Neuwiller forms a sort of French peninsula on Swiss territory.

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.

Landskrön, a castle that was feared until 1814 and is now lovingly maintained by a Franco-Swiss association, and Mariastein, where crowds of pilgrims come to pray every year, are the highlights of this superb walk, which offers beautiful views on both sides of the border.

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.

This walk can be started from the Col du Neuneich, which is accessible by car from the village of Ligsdorf (please note that this is a forest road). It is also the second part of the circular "Around the Glaserberg". It takes walkers to the heart of the Glaserberg massif, above Kiffis. You will reach a ridge offering superb panoramic views of the Swiss Jura before arriving at the Col du Blochmont and the Hornihof farm, home to hundreds of llamas grazing in the pastures.

Koestlach has a rich heritage that we invite you to discover on this circular walk, which will take you up the slopes of the Burgerwald to explore the Celtic oppidum of Kasteberg. You will end your walk through the village by discovering the prestigious furnishings of Saint-Léger Church, as well as the Chapel of Our Lady of Seven Sorrows, the legends of Kugele and the village of Erzach, the presbytery of Nicolas Delfis and the remains of an ancient Gallo-Roman settlement.

Here, you can easily travel through the centuries, from the Britzgyberg oppidum to the German military cemetery in Illfurth. However, as you cross the vast Altenberg massif and the unspoilt village of Luemschwiller, you might think for a moment that you have managed to suspend time.
