Get ready for one of the most memorable climbs in Belgium! The Montagne de Bueren isn't a mountain, but a mighty 374-step staircase that cuts right through the historic heart of the city. It's a bit of a workout, but take your time, as the views on the way up are fantastic. Once at the top, you're rewarded with a stunning panoramic vista over the rooftops of Liège and the Meuse River, right near the old citadel.
