At this point / I would like to quickly / say something about the source And specifically to quote the incomparable humorist Heinz Erhardt (1909 - 1979), who was known to a wide audience for his wit and "Another poem", with a short four-line line: "There is certainly a lot of beauty in the element, the wet.

The Largue has its source in Oberlarg at an altitude of 500 m, near the Swiss border, and flows into the Ill at Illfurth after traveling 46 km. In the 19th century, it provided energy for 53 mills spread across 34 villages.

A small entrance gives access to this fairly deep cave. It owes its name to Doctor Herrings, a village doctor with a passion for caving who died here following a landslide in 1914.

The Allée des Hêtres is made up of a remarkable alignment of around 40 trees, each over 150 years old. It undoubtedly offers one of the most beautiful views of the Alsatian Jura over the neighboring Swiss Jura.

The birth of the Alsatian river. Nice place for a refreshing break. A tap allows you to cool off with water from the spring.
