Get to know the Rhine in all its facets! Experience his tributaries Wiese and Kander, the charming cities of Basel, Huningue and Weil as well as several natural reserves like the Rhine Island on your round trip across the “Dreiländereck”. On your way you’ll meet a plethora of fascinating species in diverse habitats. Come along and discover true gems of nature in places you never expected!

 A total of eleven stops are set up alongside the route to teach you everything there is to know about the big river and two of his native inhabitants the beaver and the salmon. The extensive floodplains of the Rhine in its original state used to be an ideal home for the busy dam building beaver and the swift swimming salmon. This changed dramatically throughout the 19th Century due to the regulation of the stream and intensive hunting done by humans. For the longest time both beaver and salmon were considered to be extinct in the Upper Rhine region. However recent efforts like the installation of fish passes as well as widespread restauration and reintroduction programs pathed the way for a comeback of our little furry and scaly friends. Witness at first hand the attempts to enable the return of the once vanished beaver and salmon to the Rhine and learn how coexistence of humans and animals can be made possible. An exciting and memorable tour for all lovers of cycling, nature and animals!

You can start at any point of the tour and go in either direction. The tour takes you along the Rhine through the city of Basel. It passes the mouth of the river Birs and crosses the dam of the hydraulic plant of Birsfelden. Continue through the landscape park Wiese and across the border into Weil am Rhein in Germany. After leaving Weil the tour goes alongside the border of the nature reserve Krebsbachtal and through the towns Haltingen and Eimeldingen. After following the small river Kander for a little bit, you’ll once again arrive at the Rhine and the dam of Märkt. Cross the dam to reach the Rhine Island. Here simply follow the cycling tracks until you get to the hydraulic plant of Kembs which allows you to go across the Grand Canal d'Alsace and into France. While continuing alongside the Canal de Huningue, you’ll pass the old Lock House which marks the entrance to the nature reserve Petit Carmague Alsacienne. At the end of the canal the tour reaches the Rhine for its third and last time in Huningue. From here just follow the river for a short while to get back to Basel.

There are plenty of places to take a rest and get something to eat and drink alongside the route. For example at the dam of Märkt and in the cities of Basel, Weil, Huningue and Saint Louis. Besides that you’ll find several spots with benches for breaks during the tour.
