Description of the walk

Parking is available in a small car park at the northern entrance to the village of Chateaubourg, with around 10 parking spaces. Travelling north-south, this car park is located 200 m before the village sign.

(S/E) From the car park, head south towards the N86, without crossing it, and turn right onto the track.

(1) At the fork, turn sharply left, then turn right. Do not join the road.

(2) At this other fork, turn sharply left until you reach the small tarmac road. Follow it to the right. Beautiful view of the village and vineyards.

(3) There is a shortcut straight up the hill, which you can avoid by staying on the road.

(4) After passing Les Machons, the path on the left allows you to avoid the road, but it is not very well marked. Stay to the left of the old path, which is overgrown with brambles. Return to the road further up and, at the fork, keep right and return to the road at elevation 381.

(5) You will find the path marked in yellow and white. Follow the road to the right. Leave the two roads on the right to continue towards Margillière, following the markings.

(6) On the IGN map, the route is on the right and you used to pass two fences, but the owners no longer allow this. Continue straight ahead and, at the tarmac road, turn right and, opposite the houses in Marsanne, take the path on the left that goes up to Séverin.

(7) You have finished the climb! Take the time to take photos and admire the view. In good weather, you can see Mont Blanc. The descent is through the woods, heading due north.

(8) You will come to a wide track on the right, which you follow downhill to the hamlet of Combes.

(9) Turn left, heading north-northeast, and pass under the high-voltage power lines.

(10) Take the road on the left towards Les Bâtiments Neufs and you will come to a fork.

(11) Cross the fence to pass near the Pommeries ruins, follow the well-marked but unmarked path.

(12) You will arrive at a beautiful rock with a view of the steep-sided Rioudard valley.

(13) Carefully cross the N86 to find the passage under the railway line on your left.
Walk along the railway line on your right, heading south. You will come to a road.

(14) Turn right, then left, following the road parallel to the railway tracks.

(15) At the entrance to the village, turn right onto the bridge over the railway tracks.
Walk along the right-hand side of the N86 road at the edge of the field for about 200 metres and cross it carefully to reach the car park on the right (S/E).

Too much road on the route. We just did it in January, which is less unpleasant than in summer, but we prefer the trails.

Hello,
I am no longer in the area and cannot follow the developments of the route I posted in 2021. Feel free to suggest a route adapted to these changes.

The route is done in reverse, which allows you to enjoy views of the Rhône Valley and the Alps on the way back.
A very interesting trail above the Rioudard stream.
However, there is some uncertainty at point 11: a non-removable electric fence blocks the way with a "Private Property" sign, and 200 metres further on, at the end of the field, there is a chicane with another "Private Property" sign. Is it a good idea to go through there? If not , it would be a good idea to mention this in the practical information section, along with the risks involved. Having made the climb in the opposite direction, I forced my way through because there was no escape and I would have had to return to Glun.

A beautiful hike with lovely views, especially at the Belvédère de St Romain de Lerps 😍😍
However, the route is difficult to follow... lack of precision on the map...
A bit too much road, even if they are not very busy.
We found it to be a little longer than advertised... (18 km)...

A pleasant hike that takes you from paved roads to woodland paths and dirt tracks through fields and vineyards. The hike consists mainly of an ascent and a descent. Beautiful views, although it was a shame that the sun was not shining at the start. The route was busy on Sunday at the ST ROMAIN viewpoint. The descent was pleasant, especially in the woodland section, but the finish was a little disappointing at the edge of the RD86. Hike completed in 3½ hours.

Good hike, but with a lot of road walking; the optional trail at the start to cut across the road is overgrown with brambles....

A beautiful hike with magnificent views.
From the RN86 crossing, the return journey is a bit long.
We plan to do it in reverse next time.

Hello,
Thank you for the compliment! At point 6, I have always gone through the fences because the house we arrive at has always been a second home and there has never been anyone there.
If Visorando allows me, I will slightly modify the route to go around the land and the house and also specify that the IGN map at this location is not up to date.

An exceptional and magnificent hike!
A huge thank you to the author, this is one of the most beautiful walks I have ever done! No particular difficulty. Hike completed in 5 hours and 10 minutes.
Breathtaking panorama from the Pic de St Romain with a 360° view.
Varied landscapes throughout the hike and some pretty forest passages too.
The only downside is that the route is sometimes not very detailed and I had to use my GPS several times.
Also, be careful at point 6: do not go past the two fences, as this is private property. We met the owner there, who welcomed us but was surprised by our visit, as this land has been private for over 20 years. It is possible to go around this land.

You're right, when possible, it's safer.

The route was completed using GPS without any issues (as it was not marked).
A beautiful, varied hike with stunning panoramic views and a superb 360° view at the peak and its orientation tables. However, at point 13, we went under the bridge (green and yellow markings) to cross the road and found the trail on the other side, which was much safer and more pleasant.
