Heimersdorf walks

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.

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.

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."

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.

An easy walk that allows you to take in the forest air. Not far from Altkirch town centre, there are some beautiful views and the Erlen pond, where you can sit and enjoy the surroundings.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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 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.

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.
