Description of the walk

Access: Follow the D204 between Grâne and Loriol, pass the hamlet of Les Roberts and park at the pass, at the Chemin de Besse/Chemin du Forillon junction.

(S/E) Follow Chemin du Forillon, exit the woods and reach a hairpin bend on the left. Take the path on the right and head south for 200 metres.

(1) When you reach the "Le Guerci" marker, follow the forest path down to the right. Continue straight ahead for 2.4 km until you reach the junction with Chemin de Rouveyre.

(2) Turn left up the hill, lined with electricity poles. Leave the "Le Roc" marker on your right and climb up to "Les Moellons".

(3) From there, take the small tarmac road on your left. Enjoy the peaceful beauty of this landscape nestled between hillsides.

(4) At the crossroads just before the villas, turn right (north-east) onto the path that passes between the two gates and climbs into the woods. You will enjoy the undergrowth for 2 km, following the 42 markings. Pass a turning on your right and continue to the Y.

(5) Keep to your left, ignore a double path on the left and join a new fork

(6) Leave signpost 42 on your right and continue straight ahead for 800 metres until you come to the "Le Guerci" marker.

(1) Continue straight ahead. Your car is 200 metres ahead on your right (S/E).

Difficult to find the starting point. Description not detailed enough. However, the route is easy to follow once you get started. Beautiful views. Be careful, as the paths become very muddy in wet weather.

Hike completed in fine but cool weather (4°C).
Be careful not to park on the private road.
At the start, the description could be simplified as the notion of a hairpin bend is misleading; the "Guerci" signpost is a good landmark.
Remarkable views complemented by some beautiful residences. Very pleasant.

A very beautiful hike alternating between forest paths and lovely trails along the edge of fields. Before starting the short but very steep climb at the beginning of the second part, I was able to observe deer grazing peacefully, a beautiful encounter against the backdrop of the forest in autumn colours. The directions given are clear and precise.
The trail is not very busy, but I still came across two other hikers.

A pleasant walk without much difficulty, passing through forests and alongside fields.
A few steep climbs for complete beginners, but they are short.
We found the starting point for the walk easily.
There are few places to park (either along the start of the hike or on the side of the road).
Fortunately, the road is not very busy.

A pleasant walk; we were both complete novices when it came to hiking, but we had a great time.
Beginner friends, don't be fooled by how easy the first half is; the climb at the start of the second half taught us humility .

A lovely walk, easy for beginners. Much of it is on "trails" in the woods, with beautiful views of the Vercors and Les Trois Becs mountains.

a lovely, easy walk, recommended for people
who don't walk much. We parked
at the pass, which made it a bit longer, but we really enjoyed it
thank you for this beautiful walk
