One of the world’s most unnecessary ‘No Cycling’ signs is probably here in Liège. If you’ve been exploring the little Impasses of the Hors-Château quarter, at the foot of the citadel, you might be tempted to take the footpath to the top for a view over the city.

Not when you actually get to the staircase, though. There are 373 steps (or 374: opinions differ, and I wasn’t in a mood to check) to the top of the Montagne de Beuren, which is a bit far to lug a bike, let alone ride it.

Down or up.
