Gorges and passes in the Baronnies

An easy, well-marked hike that starts at the Ubrieux Gorges and continues through olive groves, vineyards, orchards and forests, not to mention a few passes and the sometimes rugged landscapes of the Baronnies.

Description of the walk

(S/E) Start at the Promenade des Princes de Monaco, which runs alongside the Ouvèze river. Follow the Ouvèze towards the Gorges d'Ubrieux.

(1) Just after the bridge over the river, turn left (yellow signpost) to follow the Ouvèze, pass the stadium and join the departmental road at Font d'Annibal.
Continue left along the departmental road, admiring the Gorges d'Ubrieux.

(2) Just after the bridge that crosses the river again, turn left onto the small road called Les Péchières. Follow the yellow signs and take the left-hand track shortly after the last houses. The path then climbs up the mountainside through a forest of oak and pine trees (towards Linceuil).
When the path reaches the foot of a cliff, continue to the left. Keep climbing until you reach an open area.

(3) Pass the ruins of the Bergerie des Cades and turn at the bottom of the valley where the path makes a hairpin bend before reaching the Col de Milmandre and its panoramic view.

(4) At the Col de Milmandre, rejoin theGR®9, which will take you back to Buis-les-Baronnies.
TheGR® then runs alongside rocky outcrops, which it crosses without any difficulty at the Col de Malpertuis.

(5) Continue downhill. You will come to cultivated areas with olive trees, cherry trees and vines before reaching a track on the right that leads to the small road to the Col d'Os, which you take to the right.

(6) Stay on this road (even when theGR® turns sharply to the left), admiring Mont Ventoux, and continue downhill until you reach the houses.

All that remains is to return to the car park via the small streets and squares of the village (S/E).

Be careful at the fork at the end of the ridge, as the path is not marked.

The signposting is perfect! The walk to Col de Milmandre is fairly monotonous, apart from the gorges, which are easy to navigate. We were unlucky with the weather, with non-stop rain, but the view from Col de Milmandre is beautiful. As for the return trip, apart from the road at the end, it was very pleasant with lovely views of the surrounding mountains.
A lovely outing to do in autumn with its superb colours.

A very beautiful hike with varied landscapes and good trails. The only slight downside is the approach by road from Buis at the beginning, but this is quickly forgotten once you get going.
One of the most beautiful hikes we have done, inspired by Visorando.
Thanks to its author.

A beautiful hike offering superb panoramic views, particularly of Mont Venoux! The trail is well marked and pleasant, with no notable difficulties.
A few tips:
- at the start, if the water level in the Ouvèze river is not too high (this is usually only the case during floods), take the path that runs alongside it (between the start and point 1). To do this, take the path to the left of the Pont Neuf bridge rather than following the departmental road. This avoids walking along the road and the path is pretty.
- avoid in hot weather as the hike is in the sun the whole way.
We recommend it!

A walk with a good difference in altitude in the first part, a little long the track to reach the summit and less pleasant than the descent where the view is more beautiful, a little too much road for my taste but I saw that you could deviate to a path on the left before point 6 on the last part of the road but we didn't take it because of the rain...

Route already completed on 14 July 2020 with two other friends.
The climb to the Col de Milmandre is easy and very gradual.
From the Col, I climbed up to the Rochers de Malpertuis, where I'd been last December.
Beautiful views of the Ventoux and Buis-Les-Baronnies.
I didn't return to the Col de Milmandre but took a small path on the right as I came back from the rocky bar, thinking I'd find the GR again. The path quickly goes into the forest and at times isn't very well marked. And just as I'd anticipated, I found the GR again.
The last 3/4 kilometres to Buis-Les-Baronnies are monotonous because there is no longer a path, but a road, fortunately not very busy...
In all, it took 4 hours and 15 minutes, with a 20-minute break for lunch, and about 600 metres of ascent.
I didn't meet a single hiker, but a few trail runners at the Col de Milmandre, as there was a race between Buis-les-Baronnies and Nyons today...

A very pretty route, with no difficulties, easy to follow, it's a shame there's a lot of tarmac, maybe the author couldn't do it any other way.
I saw one female hiker and two male hikers.

Hike in a group of a dozen people.
Relay cars left at the start of the Gorges d'Ubrieux to avoid walking on the D346 (of no interest until the entrance to the gorges (very well laid out with an overhanging pavement).
A very long climb through a closed and rather monotonous landscape (all the positive ascent in one go).
360° views of the Ventoux in particular from the pass.
Then an interminable descent to Buis, including long stretches of road.

Lovely walk to discover the area around Buis. Beautiful views. There were 10 of us and we left two cars at point 1 (the Ubrieux gorges car park) to avoid the D346 section of road.
The road is a little long on the descent from the Col d'Os, but the views over Buis are interesting.
This route should be avoided in very hot weather.

at the end of the hike, at the glaciere and pigne, turn left onto the yellow mountain bike path (at the path that leads to the houses, this avoids the road and leads directly into the woods).

Hello,
In mid-July, we followed this route with a group of 45 people of very mixed abilities.
Apart from a possible mix-up on the way out of Buis les Baronnies, there was no doubt about it. It was a fine route for discovering the landscapes, flora and fauna of the region. However, the final stretch on the road was considered a little long, but otherwise super fun.
It gave participants a real insight into the problems of managing heat and water.
Thank you for this route
