Where is it?
Aachen, a one-hour train ride from Cologne Bonn airport
Travel makes your body ache – and that’s the perfect reason to throw in the towel. Let yourself unwind post-sightseeing amongst the steamy waters, and when you feel fully restored, head out to enjoy the rest of this quaint city. Our tip? Make a beeline for Aachen cathedral, a Gothic masterpiece with windows that reach an astonishing 27 metres.
