Make sure you have enough gas in the tank, because Cologne is well worth a detour. Situated 30 miles from Linz am Rhein, it has a few fabulous attractions, such as Cologne Cathedral and RheinEnergieStadion. Düsseldorf, 50 miles away, is another destination that’s worth the drive. Visit Rhine Tower and Duesseldorf City Hall, two must-see attractions in the area.
