In fine weather, get off the asphalt and onto the trails of the densely forested spa garden north of the Altstadt. A brisk 20-minute walk takes you up the 264m-high Lousberg hill, where the entire city panorama unfolds before you. Get there by cutting north on Kupferstrasse from Ludwigsallee, then left on Belvedereallee.

Cycling

Cyclists can embark on a 100km bike ride along the Vennbahn (www.vennbahn.eu), a disused railway line that goes from Aachen to Luxembourg via Belgium.
