Cascade du Rudlin, Mountain waterfall in Vosges, France

Cascade du Rudlin is a waterfall in the Vosges mountains that plunges from a rocky outcrop into a basin naturally carved by water over time. It sits at roughly 850 meters in elevation within a forested mountain landscape.

The waterfall sits on the traditional boundary between the villages of Valtin and Plainfaing, a natural marker that has long separated these two communities. The water has carved its path through the landscape over thousands of years.

The waterfall is a familiar destination for hikers from the surrounding area who visit it regularly throughout the year. The roar of water falling into the natural pool creates a place where locals pause to appreciate the raw power of nature.

The cascade is reached on foot from the Rudlin hamlet side, southeast of the Étang des Dames; the stream drops about 100 metres above the valley floor. The path crosses uneven, wet rock near the fall, so wear sturdy shoes and watch your footing. The site lies on the boundary of Le Valtin and Plainfaing.

On 27 May 1944, during an aerial battle between German and American fighters over the Hautes-Vosges, an aircraft crashed near the cascade du Rudlin. The waterfall itself was classified as a natural site in 1910.
