As I grew up in the southeast of Holland next to the German and Belgium border I consider Aachen, Germany as my base. Because of that I travel to Germany often and mostly start my blogging trips from either Cologne Airport or Dusseldorf Airport. The Cologne - Aachen stretch is probably one of my most traveled routes in Germany and because there are many ways to complete this route I wanted to help you find the best way to get from Aachen to Cologne.
