Parking is available in Alaise, at the start of the Boucle de la Gauloise, next to the Calvaire at the corner of Rue du Bois des Bornes and Rue de Sur Cey. Yellow and blue signposts, Boucle de la Gauloise. Some sections are unmarked.
(S/E) Pass the Calvaire and go down Rue de Sur Cey. Turn right and head back up towards the church.
(1) Immediately turn left onto Chemin de la Gauloise, passing the bust of Alphonse Delacroix. Go up to the right onto the D139 for about 50 metres and take the small road on the right again (towards Vestiges Gaulois, Belvédère de Chataillon).
(2) At the car park, continue straight ahead on the stony road, passing through pine trees. When the path loses its stone surface and turns sharply to the left, go straight down the forest path (starting at the foot of sign 11). You will find yourself in a strange landscape of twisted, moss-covered trees. At the sign for "Poste 7", the road becomes a footpath and leads you to the Roches aux Corneilles viewpoint overlooking the upper valley. Please take care! There is no danger, but proceed with caution as the area is not secure.
(3) Turn back to the car park.
(2) Turn right onto the beautiful stone path that starts at the foot of the information sign. You will arrive at the ruins of an ancient Celtic village. Walk about ten metres to the right and back to find the first rock shelter. Return to the path and go down the small steps opposite to a second shelter. Continue along the path that runs along the bottom of the rocks to a third shelter. Shortly after the remains of the huts, don't miss the small path on the right leading to the magnificent viewpoint over the Lison Gorges.
(4) After the viewpoint, continue to the right.
(5) Three hundred metres after the viewpoint, leave the path and turn right (towards Chiprey). Follow the signposts.
(6) At a crossroads, at a signpost on the right of the path, take a hairpin turn to the right onto the path that descends the hillside. You will come to a gravel path and then the D139, which you follow downhill to the right.
(7) Cross the Lison and turn left onto the D476, following the river for 1 kilometre towards Myon.
(8) At the next signpost, turn left onto the small gravel road (towards Alaise). After the footbridge over the Lison, at the fork, climb up to the right.
(9) Halfway up the slope, at another fork, continue climbing up the left-hand road (Boucle de la Gauloise). When the road becomes paved, turn left, then immediately right to reach the calvary and the car park. (S/E)
The route includes cliff-side paths and unsecured viewpoints. The paths are rocky and slippery in places. Good walking shoes are essential and walking sticks are recommended.
