The Best Sight in Bourscheid, The Luxembourg Ardennes

Following the green Sûre valley toward Goebelsmühle—along a quiet, winding road that is one of the most picturesque in the grand duchy—look for signs for Bourscheid Moulin-Plage, where you'll see the romantic ruins of Bourscheid Castle. It looms 500 ft above the Sûre River, with commanding views of three valleys. Restorations have made this rambling hodgepodge of towers and walls more accessible; the views are magnificent and there's a snack bar.
