Salmon and beaver operation without borders
During the bike route of about 40 km in the middle of the Germany - France - Switzerland border triangle, the Rhine and its surroundings will be presented to you on 11 stations as a living natural space.
We invite you to discover the nature of the border triangle as part of the Nature Experiences – without borders project.
Hop on your bike and discover many interesting facts about the lifestyle of salmon, beavers, and other species.
The route is also marked as the "Kleiner Dreiland - Radweg".
The circuit through the three-country region offers you the opportunity to discover the Rhine in all its facets.
From the Krebsbachtal, Rhine Island and Petite Camargue Alsacienne nature reserves, to the tributaries of the Wiese and Kander, passing through the cities of Basel, Huningue and Weil am Rhein – discover real treasures, nature in unusual places and many plants and animals in diverse habitats!
Along the eleven stations of the route, you will receive exciting information about the Rhine and its two native inhabitants: the beaver and the salmon. The history of these two species in the three-country region is closely linked to that of the great river. The beaver "architect" as well as the agile migratory salmon felt extremely comfortable in the original alluvial landscape of the Rhine, with its many secondary arms and natural floodplains. During the rectification and construction of the Rhine in the 19th century, and due to intensive hunting, animal habitats were lost and populations decimated, so beavers and salmons were long considered extinct in the Upper Rhine region. It is only recently, thanks to large-scale renaturation measures, recolonization projects and migration aid facilities, that a new spread is possible. During your outing, you will discover closely how our two friends beaver and salmon disappeared, and how we now attempt to create coexistence between humans and animals. A varied and versatile route for bike enthusiasts, nature lovers and friends of animals!

Roadbook
The circuit can be started at any point and taken in both directions. It crosses the city of Basel along the Rhine, passes the mouth of the Birse and crosses the dam of the Birsfelden power plant. It continues for a short distance through the Wiese Landscape Park, then crosses the German border to reach the Friedlingen district in Weil am Rhein. After leaving Weil, we follow the Krebsbachtal nature reserve and cross the villages of Haltingen and Eimeldingen. We follow the small Kander river for a few metres before reaching the Märkt dam on the Rhine. We reach Rhine Island via the dike and follow the cycle path that crosses it. At the other end of the island, we cross the Grand Canal of Alsace at the Kembs dam to reach France. The circuit then runs along the Huningue canal for a few kilometres. We pass in front of the former lock house, which now marks the entrance to the Petite Camargue Alsacienne nature reserve. We join the Rhine again, at the canal mouth in Huningue, and after a short stretch reach Switzerland and Basel.
There are several access points to the route: the Märkt dam for example, or via the towns of Basel, Weil, Huningue, Saint-Louis etc.
You will find benches, as well as areas to rest and eat in several places.
