After two amazing days in Cologne, we traveled to Aachen where one of my friends is currently living. At the last minute we decided to climb Vaalserberg, one of the highest mountains in the Netherlands, which is also the place where Germany, Belgium and the Netherlands come together. So in a short amount of time you can "visit" three countries.
In the afternoon we explored Aachen.
Another great day.
Next stop: Maastricht.
