Description of the walk

Narrow access road, so take care from Roure in the Tinée Valley. Departure after the Marcel Kroenlein Arboretum, small car park on the left.

(S/E) From the car park, marker 241, continue along the track, Route Forestière de la Fracha. Pass under a power line and find the start of a path on the left about a hundred metres further on.

(1) Leave the track and take the path on the left. Follow this path as it climbs steadily through the larch forest.

(2) Cross the forest track and continue along the path.

(3) On the right, marker 252, follow the Crête de la Clouetta along a steeper climb. Higher up, with a bit of luck, at the end of June or beginning of July, keep an eye out for orange lilies. On your left are the slopes of the Valberg resort.

(4) The climb continues steadily, facing Mont Autcellier. Pass to the right of the cliff, climb straight up the meadow and higher up, you will see two cairns on the left.

(5) You are now at the summit of Mont Autcellier, where your efforts are rewarded with a 360-degree view of an exceptional panorama to the north-east, including the peaks of Argentera, Nasta, Mont Pèpoiri, Giraud and Mont Gravière, and to the north, Mounier and Cime de la Bonette.
Continue along the ridge to the right to reach a stony slope. Do not descend into the forest further to the right, but head towards a shepherd's hut below. Be careful! The slope is steep and there is no real path. For some time now, Edelweiss flowers have been found on the upper part in the middle of the scree.

(6) Pass close to the hut, where you may also see a few chamois early in the morning. Climb up the meadow opposite Le Pervoux for your final ascent.

(7) From Pervoux, below on the left, you can see the hamlet of Vignols. Continue keeping to the right, walking along the edge of the forest. The corner of the forest and the cattle troughs serve as landmarks.

(8) Continue downhill along the edge of the forest to the bottom of the valley. Be careful, as there are many marmot holes hidden by the grass on the slope. At the bottom, join the GR®. In late June, you will find wild tulips and globeflowers in abundance.

(9) Turn right towards the Refuge de Longon and continue to the refuge.

(10) At the Refuge de Longon, you will receive a very warm welcome from the wardens. It is a magical place surrounded by cows, sheep, goats and chickens.
Continue your descent, which is quite steep at first, along the stream to reach the foot of the waterfall.

(11) Continue south-east until you reach marker 277.

(12) Ignore the turn-off to the left and continue on theGR®. Further down, cross a footbridge (elevation 1465).

(13) You will arrive at a grassy plateau in a place called Rougios, with a few barns. Cross it to reach marker 276.

(14) Turn right to join the track, then descend to the left for another 3 km to the Barre car park (S/E).

Hello VisoRando,

Great hike. It starts in the forest where you can fill up on wild strawberries and blueberries without leaving the trail.

There are no difficulties, the description is precise and the route is easy to follow.

A cold drink at the refuge is very welcome before tackling the last few kilometres.

I recommend it 👍🏻

A very beautiful hike, with most of the route through the forest and then across the plateau meadows. We did it in the opposite direction so that we could arrive at the refuge at a reasonable hour around midday. We saw chamois and marmots along the way. On some sections at the summit, the GPS route is easier to follow as there are no markings on the ground.
Very few people, which is very pleasant.
We did it in 5 hours (including lunch) at a good pace. Thank you for the hike! Really very good.

A superb hike that comes highly recommended. Lots of flowers and marmots.
The only downside is that the refuge does not sell cold cuts to take away, as stated on their website. They only sell cheese. For everything else, you have to eat on site.

Thank you for your information. For me, the best time is late June when the trolls are in bloom. Best regards, Rando

Hike completed on Wednesday, 8 May, circular, with departure and arrival above the Marcel Kroenlein Arboretum at a place called La Barre, marker 241, where parking is easy.
Easy climb through the Fracha Forest to marker 252 with only a few trees that fell this winter to step over or go around.
The Crête de la Clauetta is very pleasant with lovely views. Snow on the ground from around 1850m, the summit is clearly visible.
Beyond that, there is 1m to 1.5m of snow on the ground, which is well compacted so you don't sink in too much at the start. Direct descent to the two pastoral huts and the point marked 2124m.
The path goes around Le Pervoux almost horizontally. With no landmarks, I make my way through soft snow, following the horizontal line. The start is very steep and not suitable for inexperienced people, and the risk of slipping is not to be underestimated. Passing via the summit of Pervoux would be a more reasonable solution, heading north-west to the point at 2031m.
The rest of the way to Portes de Longon is easier, and the large marker 278 is visible from afar.
The snow is compacted up to the Longon Refuge, so snowshoes are not necessary.
There is more snow on the ground 200m after the refuge, but the return via the GR5 is straightforward, and the waterfall is very abundant at this time of year.

A very beautiful parish-specific to Brittany hike, both in the forest and on the magnificent Longon plateau.
However, the road leading to the car park is very narrow and winding.

Hello, the bridge does not appear to be up to standard!!! Yet it is recent. A temporary path descends into the stream to bypass it. See you soon on the trails, thank you.

A very beautiful hike, but the return trip was a bit long towards the end.
At the hamlet of Rougios, on the bridge, a sign says "path prohibited". We didn't understand why and passed without difficulty.

Thanks for the information. I understand that the Longon refuge is closed this summer due to renovation work.

Hello, a very beautiful hike that took 6½ hours; classified as difficult because it is relatively long but not technically challenging.
Please note: the bridge after the Longuon refuge is normally closed, probably due to the bad weather caused by Storm Alex, but we were still able to cross it, which allowed us to complete the circular route.
