Make sure you have a full tank of gas, because Cologne is worth making a detour for. Located 25 miles from Wiehl, it offers some fantastic attractions, such as Cologne Cathedral and RheinEnergieStadion. Düsseldorf, 35 miles away, is another road-trip destination that’s worth the drive. Take a look around Rhine Tower and Duesseldorf City Hall, two must-see attractions in the area.
