(1) Don't forget to visit the wash-house and spring at the entrance to the village on your right.
Continue uphill for a few metres and take the first tarmac road, which turns left in a hairpin. After 500 metres, at the start of the descent, turn right to follow the gravel path which lies slightly below the edge of the plateau. Follow this signposted path for about 2km.

Follow the path slightly downhill into Châtellenot. Keeping to the signposts, pass the village wash-house, then under the castle, to reach a path heading east-north-east down to the valley through meadows. In the forest, keep to the right. After a kilometer of descent and at the end of the wood, at the signpost, turn left (towards Bellenot). Cross the bridge and follow the left-hand path along the edge of the gully. When you reach the lake, follow the signs to Bellenot.

When you reach the start of the dike, turn left before the small cabin, cross the small road and follow the reservoir's feed channel on its right for about 1km. Continuing to follow the signs, turn right onto the path that leads into the forest opposite a footbridge.
