The Citadel slopes are one of Liège’s best-kept secrets, for a simple reason: they cannot be seen. From the city you notice a wooded slope behind the rooftops, without realising it is a protected site crossed by paths, gardens and stairways. You can spend three hours there without meeting a tourist, ten minutes’ walk from Place Saint-Lambert.
What the slopes are
The hillside rises from the historic centre towards the old citadel, on the left bank. The site is protected and mixes several things: woods, allotments, old walls, remains of fortifications and dozens of stairways linking the lower streets to the heights.
That mixture is what makes it interesting: it is neither a landscaped park, nor a forest, nor a district. It is an in-between zone, long inhabited and cultivated, now partly returned to nature and partly maintained by residents.
How to climb
Three main entrances. The best known is the Bueren stairs, whose 374 steps leave the Hors-Château district and climb straight to the top. It is the most ตระการตา route and the busiest.
Second option: the sloping streets behind the cathedral, which climb in bends and let you enter through the gardens. Third: the stairways scattered through the district, linking the lanes to the plateau paths.
In every case, bring good shoes: cobbles are slippery, steps are high and the slopes are real.
The terraces path
It is the site’s emblematic route: a path circling the hill through the old cultivated terraces, with views opening progressively over the city. It is marked and doable with a family, provided you accept the climbs.
The path crosses shaded areas and open passages, which changes the experience entirely with the season. In summer, walk early or late: the site is an oven at noon.
The citadel
The citadel itself has largely disappeared, demolished in the nineteenth century, and only fragments, walls and embankments remain. The walker does not visit a monument: they read a landscape, with scattered remains and viewpoints that tell the strategic position of the place.
That nuance matters: those looking for a castle will be disappointed, those coming to walk will be rewarded.
Nature
The site is protected for its landscape and natural interest. You find chalk grassland, thickets and plant species adapted to dry soils. In spring the flowering is visible; in autumn the colours justify the climb.
Wildlife is discreet but present: birds, lizards, insects. It is a fragile space, and the marked paths are not a suggestion.
Viewpoints
Several belvederes offer different views. To the north you overlook the rooftops of the centre and see the Meuse stretch out. To the west the districts step down. Some viewpoints are known and busy; others are found by following secondary paths.
The best moment is late afternoon, when light falls on the facades and the city starts to look like a map.
A three-hour walk
Here is a possible route. Climb by the Bueren stairs, take in the view at the top, then the terraces path towards the north. Descend through the gardens, cross the lanes, climb again by another stairway to vary the views. Return through the lower town, crossing Hors-Château.
Allow three hours with stops, two without. The route can be shortened to an hour if you stay on the plateau.
With children
The stairs are a game, the viewpoints a reward, and the site is big enough to walk without major risk, provided you keep the youngest near walls and drops. Pushchairs should stay below: the ground does not allow them.
When to go
Spring and autumn are the best seasons: mild temperatures, interesting light, moving vegetation. Summer is bearable early in the morning. In winter the paths are muddy and some stairs slippery, but the view over the grey city has its charm.
Rules to respect
The site is protected and partly inhabited: do not pick, do not leave the paths, no fires, and respect the calm of the allotments. Waste goes back with you. These are not abstract rules: the place is maintained by residents and volunteers.
Mistakes to avoid
Believing you are visiting a fortress. Climbing at noon in summer. Going in flip-flops. Leaving the paths to ‘see further’. And forgetting the site is inhabited: the gardens are not public.
FAQ
Do I need a guide?
No, the paths are marked and the site can be done alone. A guide brings the history, not the access.
How long should I allow?
An hour for the climb and the viewpoint, three for the full tour.
Is it accessible by wheelchair?
No, the site is made of stairs and slopes. The Boverie park, below, is accessible.
Can you go in the evening?
Yes in summer, staying on the main paths. In winter night falls early and there is no lighting.
Are there toilets or a café?
Not on the site. Plan before climbing, or after coming down.
