The Mittelrhein is magical. Whether you visit the Rhine River valley by car, boat or on foot, you’ll fall in love with the steep, vine-covered hillsides peppered with castles. This wine region, which stretches from just south of Bonn to Bingen, is one of my favorites. Here I feel transported to a time of legend, and for good reason. The Mittelrhein’s crags are part of German folklore.
