Access: Coming from the Besançon - Étalans motorway, park on the left-hand side of the D492 road towards Saules, shortly after the bridge. The first part of the route is not marked, then follow the yellow and blue markings.
(S/E) Cross the road and take the path opposite the car park, at the foot of the wooden sign "Saut de la Brême". Immediately at the fork, turn right. Despite the cross, you will soon spot a path that descends to the left towards the stream. Be careful, as this old marked path is no longer maintained. When you reach the stream, head up to the right towards the back of the valley. When the path disappears, wade across the Brême and continue to the waterfall. When you see the small waterfall, approach it by passing to the left of a large rock.
(1) Retrace your steps and walk back up the path you took to descend from the main road for about ten steps, then take the small path on the right that runs alongside the stream and quickly disappears. I can't give you any more precise directions than to follow the Brême, sometimes on the bank, sometimes in the stream bed itself, jumping from one stone to another and taking care not to slip on the mossy stones.
(2) Be careful! 800 metres after the Saut de la Brême, after about an hour of jumping from stone to stone (I'm not a fast walker), taking care not to slip, you will come to a wider and deeper area. Look for a path that climbs the hillside on the left. At the top, there is a fence that cannot be opened, but you can slip underneath it without too much difficulty. Continue straight ahead to reach a pasture and climb to the right, following the edge and keeping a metal fence in your sights.
(3) Go through the gate or, more simply, through the small step at the left corner of the fence. Turn right onto the small road, then right again 60 metres after a bench, then left at the next fork at the edge of the woods. The road becomes stony as it enters the woods. A little further on, at the fork, turn left.
(4) A little further on, you will find another signpost and another fork. Continue to the right, walking alongside the ponds on your left, accompanied by the chorus of "grebeusses" (frogs, for those who don't speak the local dialect). At the wooden footbridge, turn right (despite the yellow and blue cross), following the stream to discover the ruins of the mill. Be careful! Stop at the first waterfall. Do not go to the end of the path, which ends at a dangerous cliff edge, as there is nothing more to see and it is an unnecessary risk.
(5). Turn back to the footbridge and then the intersection.
(4) Turn right. At the fork, in an open space, turn right. When you come out of the woods, continue straight ahead to reach the church in Saules. At the end of Rue de l'Église, turn left onto Grande Rue until you reach the Virgin Mary statue at the end of the village.
(6) Turn right onto the D392 towards Guyans-Durnes, the only downside of this walk, 700 metres of tarmac on this departmental road, fortunately not too busy. Turn left onto the small road that takes you across the fields and leads you to the edge of the woods.
(7) The road turns into a grassy path and quickly forks. Continue to the left. Turn left onto the gravel path and cross the road, continuing to the car park via the path to the right of the pond. (S/E)
The paths are rocky and slippery in places. Sturdy footwear is essential and walking sticks are recommended.
