Robert-le-Diable Castle Loop

This running loop is approximately 8.8 km long and generally takes around 1 hour to complete at a jogging pace. However, given its moderate difficulty and significant elevation changes, your actual time may vary based on your fitness level and how often you stop to enjoy the views.

The trail starts from Moulineaux. While specific parking details aren't provided, you'll typically find parking options near the village center or close to the access points for the Robert-le-Diable Castle, which is a prominent landmark and often a reference point for the trailhead.

This route is rated as 'moderate' in difficulty. It features significant elevation changes, including demanding and stinging climbs, making it quite challenging. While not impossible for beginners, it requires good physical conditioning. If you're new to trail running, be prepared for an 'UP and DOWN' experience with steep sections.

You'll encounter a mixed terrain of both paved routes and natural paths or 'sentiers'. The trail is known for its hilly relief within the Seine valley, with demanding climbs and descents. Some sections can be technical, and there's a possibility of muddy conditions, especially after rain. You might even come across ditches along the way.

The route offers remarkable historical and natural scenery. You'll run under the legendary shadow of the Robert-le-Diable Castle, a medieval fortress perched on a cliff. This provides panoramic views of the Seine river's meanders and breathtaking regional vistas. The trail also winds through wooded areas, including the three-hectare park around the castle and sections of the Londe-Rouvray State Forest, offering more views of the Seine and its limestone cliffs. Don't miss the Canadian Memorial as well.

The trail can be enjoyed year-round, but spring and autumn often offer the most pleasant conditions with milder temperatures and beautiful foliage. During these seasons, the risk of extreme heat or icy conditions is lower. Be aware that some sections can get muddy after rain, so consider this when planning your visit.

Yes, dogs are generally welcome on this trail. However, as parts of the route pass through the Londe-Rouvray State Forest and potentially near historical sites, it's always best to keep your dog on a leash to protect wildlife and ensure the comfort of other trail users. Please remember to clean up after your pet.

Generally, there are no specific permits or entrance fees required to access the running trails or the Londe-Rouvray State Forest for recreational activities like running. However, if you plan to visit the Robert-le-Diable Castle itself, there might be specific opening hours or entrance fees for the castle grounds or exhibitions. Always check local regulations before your visit.

Given the varied terrain and significant elevation changes, we recommend wearing appropriate trail running shoes with good grip.
