Ehrenfels Castle Ruins cling to the vineyard slope downstream from Rüdesheim, giving the Rhine Gorge exactly the kind of broken-stone drama people come here to see. The castle guarded this stretch of river traffic for centuries, and its ruined walls now frame views toward the water, vines, and the Mouse Tower near Bingen.
You can admire Ehrenfels from a Rhine boat, from the opposite bank, or from the hillside paths above Rüdesheim. The ruin itself is less a restored attraction than a landmark in the landscape, so the best visit is a walk that folds it into the wider wine-country scenery.
