Description of the walk

A car park is available at the foot of Réaumont - Saint-Cassien station. But the best option, of course, is to arrive by train.

(S/E) Take the path running alongside the railway line. Turn right onto the RD12B, go under the railway line via the pavement, then follow the path on the left-hand side of the road: on your left, Réaumont Castle.

(1) Cross the roadwith care (bend) to follow the Chemin en Lay, then turn left at the nearby junction and head uphill. Turn left again at the top of the hill and continue straight on until you reach the RD12B.

(2) Cross with care and continue along the path, almost opposite, to reach the Route de Lardinière. 

(3) Cross it, walk a few metres to the right, then take the hairpin bend onto the path on the left. You will reach the hamlet of Petit Voye. 

(4) Take the road on the right, cross the junction and, 20 m further on, take the path on the right. Ignore a grassy path on the right and continue to the next junction, opposite a wooded area. Turn left. 

(5) Turn left again to join the Route de Planche Cattin and follow it in the same direction. 

(6) Once at the foot of the hill, leave the road and take the path on the right. At the end of the straight stretch, leave the fields and head into the woods, keeping to the right, first along the ridge, then downhill towards the Fure.

(7) Turn left halfway down the slope. 

(8) Don’t miss this fork, where you must take the path descending to the right. Follow the Fure, the waterfalls and the Côte Manin ponds, created in the 18th century to supply industrial activities.

(9) Head back up the path on the left, a few metres before reaching the road. Emerge onto the plateau, leave the woods, then take the path immediately on the right to reach the hamlet of Grand Voye. First turn right then left to follow the Route du Rivier, then take the path on the right for a short detour to an old wash house. 

(10) Retrace your steps and rejoin the route on the right. Keep right at the junction and continue to a group of houses on the left. 

(11) Take the path on the left which, via a gentle slope, leads to Saint-Blaise-du-Buis, a village at the very top of the moraine of the former Isère glacier. You’ll come out onto Route de la Plaine.

(12) Turn right, keeping to the right at the T-junction, to follow Route de Celinas. Walk past the cemetery, then continue to the right until you reach the crossroads at the village exit. 

(13) First turn left then right onto the path that descends to the railway underpass and leads to Le Mouret. Take the road on the left to the Moulin de Réaumont (fish farm).

(14) Turn right and follow the RD12Awith care (bend) for a few dozen metres, then take the path on the left. Go a few metres past the junction and turn left onto the Chemin du Champ de l'Orme, which passes in front of a house, runs alongside a llama farm, then climbs gradually towards the Bessey plateau and reaches a junction.

(15) Continue straight on, cross two successive roads and reach another crossroads.

(16) Go straight on, keep to the right at the three-way junction, then turn left at the four-way junction. 

(17) Leave the main path and take a track on the right into the woods. Join another wide path and follow it to the left to reach the hamlet of Le Fays. Continue straight ahead on the road for about 100 m.

(18) Take the path on the right. Cross the road and continue along the path opposite, until you reach the station car park (S/E).

A beautiful circular route, fortunately with limited sections of road and little traffic. Due to the rain in previous days, some paths were muddy but nothing too troublesome.
Highlights:

  • Beautiful views of the Chartreuse, Vercors and Taillefer mountains.
  • The wild atmosphere at Côte Manin.
  • The old wash house at point 10.

Finally, the GPS was very useful for following the right route.

Very pleasant route, not much road!
A few wet sections, but nothing too bad.
It's best to have a GPS, as there are no signposts.

Very few signposts, so it is essential to use a GPS. Lots of mountain bikes on the first part, then very quiet. Beautiful, undulating route with few people.

The route mainly follows lovely paths; it is very accessible and varied. The Côte Manin site is well worth a visit.
At this time of year, the lack of foliage offers lovely views, particularly of the Chartreuse.
Thank you for this route.
