Champey, Castel Saint-Denis and the reserve discovery circuit
Start at the signed Champey parking for Castel Saint-Denis, approached via Maisières-Notre-Dame. The manager’s marked circuit reaches the castle area first, then explores the reserve’s habitats with small interpretation points. Use the reserve leaflet to identify this 5 km circuit: the castle-only Sentier des Remparts is a different walk.
Expect a climb and natural, uneven surfaces. This route suits walkers who can handle 5 km comfortably; shorter legs may need frequent rests. Stay on the designated visitor path around the ruins and away from unguarded edges.
