Hirtzbach walks

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 hike through the beautiful Sundgau forests dotted with ponds, with no major difficulties except for the walking time. There are many places to stop for a snack along the route.

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.

It is in late February and early March that you should go to meet spring in the forest of Saint-Bernard. This is where the snowdrops appear, signalling the end of winter.

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.

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.

On this route through the fields, you will take a small section of the Circuit de la Mémoire (Memorial Trail) with signs recounting the military exploits of the First World War. You will also have the opportunity to walk around the lake, which is impressive in size and pleasant in all seasons, with numerous benches dotted along the route.

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."

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.

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.

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.

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.

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 route invites you to discover the village of Bernwiller and its surroundings, with a quick detour into the forest to sit for a moment in front of the small Notre-Dame de l'Unterholz Chapel and admire it.

A short hike in the foothills of the Jura to discover the renovated Grand Canyon in Zillisheim, passing by the German cemetery from World War I and the Saint-Brice Chapel in Illfurth.

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.

Passing through the pretty village of Flaxlanden and its Lourdes Grotto, discover a First World War military site in the hills above Zillisheim. Learn a little about nature with the discovery trails along the route and enjoy the many views that await you along the way!

This long hike through fields and forests allows you to discover the peaceful Sundgau region of Belfort, walk along ponds and flirt with the Swiss Jura. The trail is marked with a yellow ring.
