Cascade du Rudlin is a nice waterfall between Plainfang and Le Valtin (east of Gerardmer) in the region Elzas lotharingen/Vosges, France.
From Gerardmer drive east to Colmar (D417) but then take the exit to the D23 to Le Valtin – 8km. Proceed following the D23 until you see a white chapel. A little further there is an exit to the right with a small parking and an information board (gps 48.119485, 7.041956). You also can park your car a little further at the «Auberge».
It isn’t difficult to find cascade du Rudlin, the trailhead lies behind the Auberge and leads through the forrest. From the parking at the road it is a 1 kilometer walk uphill (20-30 minutes) with an ascend of 100 meter.
