Roll out of Fort-Louis and let the ride unfold: first through the Rastatter Rheinaue nature reserve, then past Schloss Favorite and Alt-Eberstein, two castles in a row. Later comes the Battertfelsen nature reserve near Schloß Hohenbaden, followed by Altes Schloss, before Hinterwörth-Laast and Mittelgrund Helmlingen close the loop of nature reserves. With 89.9 km and 522 m of climbing, it's 98% paved, 1% unpaved, and it ends back in Fort-Louis.
