From Piolenc to the fortress of Mornas

Before reaching the plateau overlooking the Rhône valley, offering superb views to the south and north, this route takes you through old sand quarry galleries and part of a surprising drystone shelter trail. At the western end of the plateau stands the fortress of Mornas, which you can see from above but which can be reached by taking a short detour.
The only difficulty of this route is its length, as it mainly follows wide forest tracks lined with majestic pine trees.

Description of the walk

Coming from Uchaux la Galle on the D172 towards Piolenc, turn right onto Chemin Pellet Ferragut. Park at the end of the road in the designated area, at the signpost marked "Le Plumet 70 m".

(S/E) From the car park, take Chemin des Vignes. Stay on this main road until you reach the tarmac. At the next crossroads, turn left onto Chemin du Paty, towards B.U. 12.

(1) At the signpost marked "Les Aveaux 74 m", continue straight ahead towards Piolenc. Climb up this main road, D.F.C.I. B.U. 12 (Chemin des Chèvres), which curves to the right. Read the information sign marked "Attention Danger". Go through a barrier.

(2) At the T-junction, turn left for a round trip to the old sand quarry galleries.

(3) The galleries are on the left. Retrace your steps.

(2) Continue straight ahead. The track curves to the left. Notice the scars of the fire in the summer of 2022 in the woods on the left. At the next junction, turn right onto the D.F.C.I. B.U. 11 track (Chemin des Sables). Pass through a barrier.

(4) At the crossroads, turn left onto Chemin des Issards, then immediately right (yellow cross). At the top of the hill, turn left. Continue between the truffle fields before entering the pine forest. At the T-junction, go down to the left to join a path on the flat.

(5) Turn right. Pass a parking area for cars where there are two signs: one provides information on the regulations governing access to the Bollène-Uchaux forest from 15 June to 15 September, the other on the Sentier des Drystone Shelters. Go past the barrier. Ignore the D.F.C.I. B.U. 130 track on the left and descend opposite. Go around a beautiful olive grove on the right, passing above it (traces of paths) and climbing up the dry stone terraces that mark the boundaries of the terraces. Look out for a wooden sign on the right saying "drystone shelter".

(6) At the wooden sign, note the presence of a "cagnard" or low stone wall built at a right angle. Pass over a collapsed drystone shelter to reach a beautiful drystone shelter in very good condition. Descend and continue around the olive grove. Just before reaching the track, note another drystone shelter and large dry stone walls. Continue on the D.F.C.I. B.U. 130 track to the right.

(7) A little further on, small wooden signs indicate a path leading to drystone shelters on the right: you can make a round trip on a marked circular route (not shown on this map). Continue and turn right at the next barrier onto the Chemin de Gourreou, which is tarmac. Go through a barrier. Cut across the bend in the track, going straight up, then continue along the track.

(8) At the next junction, keep left on the D.F.C.I. B.U. 14 track. Stay on this main track, ignoring the turnings on the left and right, until you reach an orientation table.

(9) Continue climbing to the right towards the chapel (signpost "Cantarelle 181 m").

(10) Look for the start of the return trail marked in yellow and red on the right before the chapel.
- Pass in front of the Saint-Baudile Chapel and keep left on the path marked with a green line.

(11) Climb up, turn left, then leave the yellow and red marked trail that branches off to the right (towards the fortress) to make a round trip on the trail that descends steeply to the left. It leads to a beautiful viewpoint over the fortress of Mornas: the two trails are on two rocky spurs of the cliff facing each other.

(12) Retrace your steps.

(11) Continue straight ahead for a superb view of the Rhône valley to the north. Descend towards the chapel. Reach the intersection after the chapel and the start of the trail marked on the way there.

(10) Turn left to follow the GR® de Pays du Massif d'Uchaux. Follow the yellow and red markings of the GR®, which sometimes joins the track you followed on the way up, while staying as close as possible to the edge of the cliff.

(13) Pass a rocky outcrop where you will need to use your hands briefly. Shortly afterwards, rejoin the track at the crossroads you passed on the way there.

(8) Follow the B.U. 10 track opposite (yellow and red GR® de Pays markings). Further on, at elevation 160, descend onto the first path on the right. At the next junction, turn left. Continue along the path that descends towards Mont Ventoux, towards the pine forest, until you see a wooden sign indicating "Drystone Shelter" on the right. Walk back and forth until you find a beautiful drystone shelter with a distinctive shape, in good condition. Then take the path on the right.

(14) At the next junction, turn right onto the track and follow a small marked circular on the left to discover three more beautiful drystone shelters. Return to the previous junction.

(14) Go up to the right on the track until you reach track B.U.10.

(15) At the "Le Crestaïre 161 m" signpost, continue straight ahead, then keep to the right on track B.U. 10, GR® de Pays. Stay on this track at the various intersections, go through a gate and you will find the car park (S/E) just after.

Notes

In the area where the old sand quarry galleries are located, several "Caution: Danger" signs indicate the presence of underground galleries (used for lignite extraction). Due to the high risk of landslides, please do not approach the edges of the path, in other words, do not leave the path.

Please note: from 15 June to 15 September, access to the Bollène-Uchaux forest is restricted due to the risk of fire. Telephone information line from 6pm: +33 (0)4 28 31 77 11

Worth a visit

During the hike, you will come across several wooden signs marking a "sentier des drystone shelters" (drystone shelter trail). The "Mornas Aujourd'hui" association is responsible for clearing and promoting a large number of drystone shelters in the Mornas area. The signposts allow you to complete a circular route of about 5 km in an anti-clockwise direction from point (6) by taking the track that goes uphill.
More information is available on their Facebook page and on the sign at point (6), which provides a map and two routes.

 Always be cautious and plan ahead when you're outdoors. Visorando and the author of this route cannot be held responsible for any accidents occurring on this route.

The route was very good, the view of the fortress was good. Be careful in this area, it is very steep, if you are with children or elderly people.

A beautiful walk that took us above the fortress of Mornas, with the option to descend into it
It was a busy route, given that it was a public holiday
No particular difficulties, but we avoided point 13
The sand quarries are worth seeing, but stay at the entrance: don't hesitate to make a round trip
However, we had difficulty completing the Drystone Shelter route. We started it but turned back, having had trouble finding the route to make the circular route
We had lunch in a shady spot right next to the start of the drystone shelter route

Thank you for your feedback. Indeed, there was an error in the description regarding the waypoint numbers. I have just corrected it.
As for the rocky outcrop, it can be fun to climb over it, but it is actually easy to avoid by following the track that runs parallel to the suggested route.
Kind regards
Francine

Hello, great hike except for the section between points 10 and 13, where we recommend taking the starting trail rather than the one on the map, because at point 13 you have to "climb" a rock to continue, and there is an error in the description, since stage 14 says << pass a rocky outcrop where you will need to use your hands >> whereas stage 14 is easy to pass, this description would be more appropriate for stage 13

A very pleasant hike with numerous viewpoints and sections through the woods, which is nice in summer.
There is also an interesting route along the Chemin des Drystone Shelters.

A very beautiful hike. A very interesting route. The sand caves, the drystone shelters, the chapel of St Baudille and the fortress of Mornas. Some very beautiful views. To follow the route, I used the Visorando app with GPS tracking. I hardly used the paper description at all. I recommend this hike.

Hello Visorando
A very beautiful hike
We just had a little hiccup at the chapel
about halfway through, but we found our way back at point 8
So everything was fine
The PDF is really reliable
Best regards

Having retraced this route on 17 December last year, I noticed that two information boards had been installed at the point (6). One indicates that access to the Bollène-Uchaux forest is restricted from 15 June to 15 September for fire protection purposes. The other, from the Association Mornas Aujourd'hui, provides a very detailed description of the Sentier des Drystone Shelter. I have just made some minor changes to the description to take these into account.

An interesting route. The sand caves, the drystone shelters, the chapel of St Baudille and the fortress of Mornas
Point 12 overlooks the fortress, but it is possible to get there via a side path.
avoiding the DFCI is a bonus.
Completed in 3 hours 50 minutes. Thank you for the route
