The best cycling routes around Köstlach

This is a (often dry) fountain at a highway intersection in the village called Winkel, not the location of the source of the river Ill; that's 850 meters to the south at another highlight: https://www.komoot.com/highlight/4448431 But the source is often not producing much visible water. So it's perhaps fitting that Komoot's automatic translation doesn't reliably avoid messing up place names. While that's confusing for users, we can try to focus on the humor: Unless the highlight author puts the title "Illentsprung" (German for "Source of the Ill river") in quotation marks, it is displayed to me in English as "Source of pain" ... 🤣 ;-)

Quiet cycle path where you can spot many storks, including at the Storkhous in Raedershof and at the beautiful Church of Saint-Martin-des-Champs.

The village is known in Alsace because the Ill River, which joins the Rhine a few kilometers north of Strasbourg, has its source here. The source of the Ill, located east of Winkel at a place designated in 1591 as Illentsprung, meaning origin of the Ill, in an orchard on the slopes of the Glaserberg. Its current powered the waterwheels of sawmills and mills.

Idyllically situated at the end of the Lützeltal.

Small regional museum in a restored farmhouse in the centre of Oltingue. The museum shows the daily life of farmers in the Sundgau in the 19th and early 20th century. The collection includes utensils, tools, religious objects and furniture, spread over several rooms and an old barn. The original faience stove, a ‘Chunscht’ bench and a baroque outdoor pulpit are striking. Visits are possible from March to November, usually on Tuesdays, Thursdays, Saturdays and Sundays from 15:00 to 18:00.

The current parish church of Oltingue was built between 1827 and 1831 in late classicist style. Striking features include the triangular pediment above the round-arched portal and the Callinet organ from 1843, which is still in use. Together with the presbytery and the former school, the church forms a well-preserved village ensemble from the Louis-Philippe period. The church replaced an older mother church outside the village.

Oltingue is a quiet village in the Sundgau with a late-classical village ensemble around the church of Saint-Martin (1827–1831), the rectory and the former school. The Callinet organ (1843), the double staircase of the rectory and the facade details are striking. There are several historic houses in the village, including half-timbered houses from 1695 and a farm from the 16th century. To the east lies the chapel of Saint-Brice, a former place of pilgrimage with a baroque altar and an outdoor pulpit.

Raedersdorf is located in the southernmost part of Alsace, in the hilly landscape of the Sundgau, close to the Swiss border. The village is surrounded by forests, springs and hiking trails leading to heritage sites such as the Église Saint-Étienne with its baroque interior and Callinet organ, and the Mariabrunn chapel in the forest. Its location between French-speaking and German-speaking Switzerland makes Raedersdorf a place where cultures come together.
