Acher, River in Baden-Württemberg, Germany.
The Acher is a river in Baden-Württemberg that rises in the Black Forest and flows northwest toward the Rhine Plain. It passes through narrow forested valleys in its upper course before widening as it reaches the lower, flatter stretches near the Rhine.
In the Middle Ages, the river powered mills and small workshops along its banks. During the 20th century, its lower course was regulated and partly redirected in the Rhine Plain to protect the surrounding land from flooding.
The valley along the river is used by walkers and cyclists who travel between the Black Forest and the Rhine Plain. Along the banks, meadows, forests and small villages follow one another, shaping the character of this part of Baden-Württemberg.
Walking and cycling paths follow the river, especially in the upper valley where the terrain is easy to navigate. Conditions vary by season, and a visit during dry weather makes the trails more comfortable to use.
The Acher is fed by several small streams that meet in a high valley of the Black Forest, making it hard to pinpoint a single source. Depending on water levels, the point where the river truly begins can shift, which catches many visitors by surprise.
