There is material to climb in the Ardennes. Several sites have been identified and routes have been opened there by Ardennes climbers. If you like climbing, you can take on the Roc-la-Tour in Monthermé, the Roche aux Corbeaux in the Hautes-Rivières, or the Roche aux Corpias in Tournavaux. These exceptional geological sites are also climbing spots accessible freely or accompanied by local guides. Be careful, however, to practice climbing in respect of the sites, the species that live there and during the authorized periods.
