Isteiner Schwellen, Rapids at Efringen-Kirchen, Germany.
The Isteiner Schwellen extend over one kilometer along the Upper Rhine, featuring stone formations and water patterns creating natural obstacles in the river.
These rapids mark the last remnants of a Jura massif that originally blocked the Rhine's northern flow until Johann Gottfried Tulla's river modifications in the 1800s.
The riverside area transforms into a gathering spot during summer months, where visitors from Germany, France, and Switzerland converge for swimming and sunbathing.
Multiple hiking trails connect to the rapids, with a dedicated parking area and observation platform providing direct access to this natural formation.
The water level at these rapids dropped approximately 11 meters following the construction of the Grand Canal d'Alsace in 1928, revealing additional rock formations.
