Climbing outdoors in Belgium: access, permits and guests

Belgium's rock is almost all in Wallonia, along the Meuse and the Ourthe. You can't simply turn up and climb, though: every Belgian crag is on private, municipal or regional land, and climbers get in through the federations. Here's how access worked in October 2026, how to bring a friend who isn't a member, and where to start.

Why you need a federation

The Club Alpin Belge (CAB), the federation for French-speaking Belgium, explains that climbing on any Belgian crag needs the landowner's permission. The CAB, the Flemish Klim- en Bergsportfederatie (KBF) and the UBS have agreed terms with the owners, usually for a fee, and arrange the planning and environmental permits that set conditions for climbing and for looking after the cliffs. Members' subscriptions pay for all of this and include insurance. If you don't belong to the CAB or another climbing club or federation, such as the KBF, the UBS, the Dutch NKBV, France's CAF or FFME, Germany's DAV or another national alpine club, you have no access to these crags. Even on public land, the forestry code only lets you use paths and tracks, not the rocks.

The KBF's own FAQ, from March 2025, says the same. The federations pay rent for the crags and car parks, and arrange environmental permits with the municipalities, Wallonia's nature and forestry department and Natura 2000. Every climber needs a valid climbing permit, which comes with KBF membership: without one, you're on private land unlawfully and you aren't insured if there's an accident. Members of federations that belong to the UIAA, the international mountaineering federation, may climb on Belgian crags, except at Marche-les-Dames.

Bringing a friend who isn't a member

Both federations let members bring non-members for a day:

• The CAB's day invitation. An adult CAB member can invite up to two non-members at a time, for one day, by emailing the CAB's secretariat at least eight days ahead. Since January 2024 it has cost €11 for adults and €6 for under-18s to climb outdoors, or €2 indoors. It covers crags in Belgium run by the CAB, the KBF or the UBS, as well as Marche-les-Dames, but only up to two massifs a day, both run by the same federation. The guest is insured for injury and third-party liability, and the member has to stay with them, provide their equipment and have the skills to look after them.
• The KBF's klimtoelating. A KBF member aged over 14 can bring non-members, staying with them while they climb, after applying for a klimtoelating through the KBF's online form. It covers access to the crag and insurance for the day, and can't be cancelled.

Groups have to book: at KBF crags from ten people, at least three days ahead, and for more than eight people at the CAB's sites. Marche-les-Dames has its own rules: the CAB only issues individual invitations there, or for its clubs' own activities, and non-Belgians may be turned away if they haven't asked in advance.

Where to climb

Freÿr, on the Meuse between Waulsort and Anseremme near Dinant, is the highest crag in Belgium. It has about 700 routes from grade 2 to 8c+, between 15 and 120 metres long, many of them three to five pitches, and most have fixed bolts. The rock varies from slabby limestone to steep, pocketed dolomite. The first route went up in June 1930, and the CAB, which rents and manages the site, runs the Refuge Duchesne and a bivouac there for its own members and partner clubs' climbers. RTBF calls it the Belgian Verdon.

Along the Meuse towards Namur, RTBF picks out the Rochers du Paradou at Yvoir, a sunny limestone slab suited to beginners, the airy cliff at Dave, above the river, and Beez, near Namur, with more than 400 demanding routes. Further east are Corphalie, at Huy, and the Rochers de Sy at Ferrières, on the Ourthe, while Landelies, near Charleroi, is a former quarry. The KBF also names Yvoir, Pont-à-Lesse and Hotton among its crags, and opened a new one at Spontin in 2024.

On the rock

Some crags close for part of the year or have their own rules, for example to protect nature or to keep to agreements with landowners, so check the federations' crag pages and the noticeboard at the crag before you climb. The KBF's code of conduct asks climbers to:

• park only where it's allowed, and come by public transport or share a car if possible;
• take their litter home and use the toilets provided for climbers;
• use as little chalk as possible, keep the noise down and light no fires;
• climb as a roped party rather than top-roping, and stay on permitted routes and paths;
• respect closures, and wear a helmet.

The federations look after the crags with volunteers from the Belgian Rebolting Team, and anyone can join its rock work days.

Learning to climb outside

The KBF calls rock climbing a risk sport and advises getting experience in a climbing hall first, then taking an outdoor lead course with one of its clubs: its KVB 2+ and KVB 3 courses teach leading on rock, single-pitch and then multi-pitch. Some halls help with the move, too: Klimzaal Bleau in Ghent runs rock-climbing trips, and Entre Ciel et Terre in Louvain-la-Neuve runs crag courses of one, three or five days, for climbers who can already tie in and belay on a top rope; the five-day course takes children from ten.
