With pure chaos of Cologne's traffic condition.. by Maria250
..one better travel into Cologne by train, airplane, helicopter, parachute or anything but CAR!!But if one like to stick to its car (like I did) you better forget about parking spots in that city's center. There are parking houses but they are very tiny, and ok only for those that drive some small German, cube like VW. A regular truck/van won't fit in any of those parking houses.
Yet there are comfortable parking places along Aachener Strasse way out of town's center(around housing numbers 300 to 400). Cost is up to 4 euro for 4 hrs. To get into town after parking the car one can jump on the tram (direction Heumarkt) that rides along Aachener Strasse.
