Car park in front of the old lime kilns on Rue des Fours à Chaux in Chalezeule. The route is marked by signposts at the junctions.
(S/E) Walk round the kilns and return to Rue des Fours à Chaux; turn right, and at the end of the street continue straight on along Rue des Vareilles du Milieu. Then head up to the left along Chemin des Buis to reach the viewpoint overlooking the Doubs valley and the ruins of the feudal castle of Montfaucon.
(1) Set off again along the path at the far end, passing between two large stones. After 200 metres, ignore the path leading down to your left and head up to the right. At the first fork, carry on straight ahead along the left-hand path. At the next fork, just before a signpost, head down to the left towards the Grotte du Renard.
If you walk past it without noticing, don’t panic – carry on to the signpost and head down to the left (towards Près de Vaux) for a few metres, then turn left again for a round trip to the cave.
(2) Leave the cave by continuing along the path; when you come to another path, carefully head down to the left (handrail and step). Further down, take a wider path on the right. Continue to the dead end of a small tarmac road (marker post 113, towards Mont de Bregille).
(3) Head up to the right, passing over some old ruins, perhaps former ‘cabordes’ – those winegrowers’ huts commonly found in the Besançon hills. You’ll come across a path at right angles to the one you’re on; take this to the right for about fifty metres. Take the path that climbs steeply to the left. At the top, you’ll come to a wide forest track; turn left onto it for a few dozen metres to reach the ‘dry grasslands’ of the Grand Désert.
(4) Head straight ahead across the open space, following the forest track, guided by a signpost (121) at the edge of a small tarmac road. Cross the road and continue straight on along the gravelly path that winds through the grasslands, keeping the edge of the woodland on your left.
(5) Enter the woods on the left (post 129e), heading towards Fort de Bregille, to reach the cliff-top path (129d). Then turn right. Carry on straight ahead, following the top of the moats, and go down a few steps on the left.
Do not take the dangerous path that runs along the top of the walls. You’ll pass a superb view of the Citadel and the Besançon hills.
(6) Descend into the moats and turn left (129c) to reach the fort’s esplanade (picnic table), which offers another view of the Citadel and the old town of Besançon. Head towards the radio mast and turn right towards the ramparts (trail 3) along the stony path, then weave your way to the left to take a curious detour around the moats and retrace your steps.
(5) Cross (at marker 129e) the lawns, but this time diagonally, towards the car park, passing between the barriers. Head right onto the small tarmac road, passing a metal barrier about fifty paces further on (marker 122 Grand Désert).
Turn left onto the stony path towards Les Vareilles-Dessus and enter the woods. At the nearby fork, take the wider path on the right. At the next two crossroads, carry on straight ahead. You’ll reach the fitness trail (station No. 7) and a crossroads. Carry on straight ahead until you reach a nearby gravel farm track (signpost 130).
(7) Turn right, still heading towards Les Vareilles, until you reach a fork (marker post 132). Carry on straight ahead.
At the next fork (trail marker 3), head down the widest path on the left to reach a gate. At marker post 136, turn right (towards Chalezeule), immediately passing two paths on your right.
You’ll arrive at the rear of a house and walk alongside a wire fence. The path turns at a right angle, climbing to the right, and joins another path at right angles (trail marker on a tree). Turn left onto a path of large stones to reach the rear of some buildings again and a crossroads.
Turn right, following the fence to return to the Clementigney viewpoint, and make your way back at a leisurely pace to the car park (S/E).
