Koblenzer Laufen, Natural rapids on the Rhine River between Waldshut, Germany and Koblenz, Switzerland.
The Koblenzer Laufen form a section of the Rhine between Waldshut and Koblenz where water flows over limestone formations with a noticeable drop. The rapids generate strong currents that make the water churn and foam.
The section was recognized as a natural obstacle to navigation in ancient times and played a role in early trade routes. Specialized techniques for safe passage developed over time and were passed down through generations.
The rapids shaped local boating traditions, with Koblenz rivermen holding exclusive responsibility for guiding vessels through this section. Visitors can still encounter stories about these specialized skills in villages along the banks.
Swimming and paddling are not permitted on the German side due to strong currents and danger. It is better to watch the rapids from riverside paths or use viewpoints in nearby villages.
At low water levels, limestone banks become visible showing remnants of ancient geological processes. These exposed layers give visitors a rare glimpse into the geological history of the region.
