Start from the church in Villers-devant-Orval: parking nearby.
(S/E) Take Rue des Casernes and, after passing the Orval footpath on your right, you will reach a wayside shrine at a fork in the road.
(1) Take the small road on the left and follow it to a mobile phone mast.
(2) Turn left at the next path. At the next fork, keep left to go downhill to the Ferme du Bois-Le-Comte.
(3) Turn right towards the Source du Ourdel, located on the left-hand side of the path.
(4) Continue in the same direction. At the next junction, go straight on, ignoring the paths to the right and left, and follow a small, flat path to reach the border.
(5) Cross the border, continue for about 200 m before turning right to climb and then descend along a path marked by old boundary stones demarcating the Kingdom of France and the Orval Estate. Join a wide path marked with multiple signposts and keep left to reach the bottom of the Williers Stream valley.
(6) Take a sharp right-hand bend and descend slightly to follow the course of the stream. Ignore the path descending to the right and shortly afterwards you will reach a fork: information board, tables and benches.
(7) Head left, cross the Ruisseau de Williers and a wetland area via a boardwalk, then walk along flat ground beside the Prés de l'Abbaye d'Orval (nature reserve) to emerge onto the N88 near the abbey. Continue to the large crossroads.
(8) Turn left, then quickly turn left onto an uphill path. Shortly afterwards, head down to the right towards the abbey: you can visit the ruins of the old abbey and the museum.
(9) Return to the large crossroads via the road.
(8) Cross the N88 again and head towards Villers-devant-Orval along the N840. Leave the road to the right at the first bend and head towards the forest until you reach the first crossroads.
(10) Turn left and head towards the Bois de la Vierge (bench) at a fork in the path.
(11) Ignore the path leading uphill to the right and continue to the wayside shrine you passed on the way out.
(1) Keep going in the same direction. At the next fork, turn left onto the Sentier d'Orval. After the cemetery, turn right onto Rue Théophile Noël to return to the church and the starting point (S/E).
