Mercus-Garrabet was a short but memorable stop for us because of the unusual Pont du Diable, the Devil’s Bridge, hidden below the road in a wooded section of the Ariège valley. We stopped at the small parking and picnic area on the D73, immediately above the bridge. There were only a few spaces, but we had no difficulty stopping there with our 23-foot-long motorhome. The area had three picnic tables and no motorhome services, so it was a simple place rather than a conventional motorhome aire, but its location made it particularly interesting. The bridge itself is only a short walk downhill from the parking area.
The Pont du Diable is a small historic stone bridge crossing the Ariège River. Reaching it means following the path down from the parking area, and the setting changes quickly from the roadside to a much more natural environment beside the river. The bridge is surrounded by trees and rock, and the water below gives the place a completely different atmosphere from the road above. It is the kind of stop where there is no need to spend a whole day: the walk down to the bridge and the surrounding landscape are the main reason to come.
The bridge is also connected with the legends that gave it its name. Like many medieval bridges in France known as Pont du Diable, its construction has traditionally been associated with the Devil in local folklore. The story reflects a common European tradition in which difficult or apparently impossible bridges were attributed to supernatural help. Whatever the historical reality behind the legend, the name has remained attached to the bridge and has become an important part of its identity.
The location is also interesting from a geographical point of view. The Ariège has carved a narrow valley through the foothills of the Pyrenees, and Mercus-Garrabet lies in this transition between the lower valley and the mountains. The river, wooded slopes and rocky surroundings make the area feel much more remote than its actual distance from Foix would suggest.
For us, the appeal was precisely this combination of a very simple stopping place and an unusual local landmark. We did not need a large campsite or a fully equipped aire: we could stop beside the road, have the motorhome nearby and walk down to see the bridge. The picnic tables also made the location useful during the day, although the parking area itself is small and there are no services for motorhomes.
Mercus-Garrabet was therefore a relatively brief stop, but one that fitted very well into our journey through the Ariège. The Pont du Diable is not a monumental attraction on the scale of the castles and historic towns further along the route, but its position beside the river and the short walk through the landscape make it a pleasant place to stop and explore. For us, it was another example of how travelling through this part of France can lead to small places with their own history and character, even when they are not major tourist destinations.
