From Chalèze, park along the D323 and the bank of the Doubs on the right 50 metres before the sign for "Arcier, commune de Vaire".
(S/E) Follow the D323 towards Arcier, which allows you to discover the beautiful properties and buildings along the road from the road: chapel, castle on the left, and thus avoid parking problems in the small car park at the springs (capacity of 8 cars, which is insufficient on some weekends).
(1) Take Rue des Sources and follow the path along a property fence, which climbs gently to the edge of the forest.
The first bridge crosses the Bergeret Spring and offers a direct view of both the water flowing out of the rocks and the first waterfall.
(2) At the stairs to continue the hike, descend 50 metres to the right and admire the water cascading down the masonry structures from the Source d'Arcier. Climb back up these 50 metres, turn right and access the main Source d'Arcier. Retrace your steps and take the stairs with wooden risers.
After climbing these stairs, continue uphill on theGR® (red and white) marked trail.
(3) At the change of slope and crossroads, continue straight ahead, descending slightly and following the signs. Follow the well-marked path until you reach the crossroads with a forest road.
(4) Take the forest road on the right, going downhill. At the next crossroads, continue straight ahead until the next right-hand bend on the tarmac road.
(5) Outside the bend, find a path on the left that runs alongside the road for 30 metres and find a path on the left between stacks of wood (markedGRP® Red and Yellow) that descends. If you cannot find this path, don't worry, continue down the road for a few dozen metres and turn left before the house, then go back up this path for 30 m and take the path on the right after the woodpiles.
Walk down into the woods until you reach the road at the entrance to Chalèze, then go down the big bend on the right.
(6) Take the first street on the right, then immediately after, on the left, take the unmarked path that passes in front of the telephone pylon. Continue straight ahead, descending along the Côte de Joux. When you see thefirst houses of La Canaie, do not be tempted to go straight down to the main road (too steep and in poor condition), but continue on the right, descending to the bottom of the valley, then turn left along the stream to the D323, passing a few houses.
(7) Turn right onto the D323 and follow the Doubs, which the road overlooks in a large circular loop, to the car park along the main road before entering the hamlet of Arcier (S/E).
