The area is access sensitive!

As for all climbing sites in Belgium, you must be member of the climbing federation that manages the site (here the Club Alpin Belge). The CAB has reciprocity agreement with the other belgian federations (KBF, UBS) and the NKBV (Netherlands). The active members of other climbing federations of UIAA are also allowed for climbing if they also have an insurance for civilian liability covering climbing activities.
Parking : the cars can park on a big parking place between the railway and the marine. There can be a lot of cars during sunnies week-ends so park closely to each others and perpendicular to the road.
⛔️🛤
IT IS STRICTLY FORBIDDEN TO CROSS THE RAILWAY.
Just walk along the road and take the bridge over the railway. A good path starts from the bridge and lead to most of the cliffs, except the "Caribou". The main path is continuing behind the "Centenaire" and goes up in a valley to the Marche-les-Dames forest. At the beginning of the valley you have the "Jokari".To go to "Ecrin, Jonction and Cellier), you have to continue along the railway for about 150 m. For the "Caribou", from the bridge, continue about 75 m, go over the road protection rail and follow a small and steep path to the right. See map in the "photo" area.
Coming down. For most of the routes, you can lower off or abseil. If you want to exit to the summit, there is a small path almost following the wooded crest and joining the main path in the valley just after the "Jokari". All the ravines between the cliffs are impassable and strictly forbidden (Natura 2000 sensitive protected area).
