The departure point is the Bibracte Museum car park.
(S/E) Go up a small road that runs between the museum and the restaurant "Le Chaudron".
(1) Take the track that climbs to the left of the road, just after the barrier. Note the Barlots Tomb, known as "la Dame des Barlots". Climb up to the D174 road and arrive at the Porte du Rebout.
(2) Go up the road on the left. Just after the reconstruction of a Murus Gallicus, turn left behind the rampart, go down into the valley and climb straight up to the Fontaine Grenouillat.
(3) Turn right. Pass under the thatched roof, following the yellow markings.
(4) Continue straight ahead. Pass under the terrace (you can climb a few metres to admire the view and visit the tiny Saint-Martin Chapel).
(5) Continue straight ahead and cross the road.
(6) Be careful, take the path directly opposite, this time under the rampart. Continue straight ahead and cross the Ruisseau de la Fontaine Saint-Pierre stream.
(7) Pass under the Roche Salvée, still under the rampart.
(8) At the Ruisseau de l'Écluse, cross the rampart and continue straight ahead to Theurot de la Wivre, a spectacular large rock.
(9) Continue along the ramparts to the Porte du Rebout. Take the D274 on the left for 100 metres to reach the crossroads from the outward journey.
(2) Turn left at the edge of the forest. Go downhill and turn onto the first path on the right. When you reach the road, without taking it, zigzag along the path on the left and then the one on the right. Pass behind the museum.
(10) Continue along the path to return to the car park (S/E).
