Be sure to have plenty of gas in the tank, because Düsseldorf is worth making a detour for. Situated 35 miles from Hamminkeln, it’s home to some terrific attractions, such as Rhine Tower and Duesseldorf City Hall. Moenchengladbach, 40 miles away, is another road-trip destination that’s worth the trek. Visit Borussia Park and Rheydt Castle, two must-see attractions in the area.
