Description of the walk

To get to the start, between the Colmiane ski resort and heading towards Saint-Dalmas, take the small road called "Les Millefonts" on the right, in a hairpin bend on the left. The hike starts from the car park at the end of the road, which is open to all vehicles.

(S/E) Take the trail above the car park to join theGR®52and climb up to the Col de Veillos via a trail that winds its way up the grassy slope.

(1) Take the path on the right that continues up the ridge, then continue along the mountainside to reach Lac Long. Go around it on the right, the path climbs a little, joins Lac Gros and continues on the left to reach the Col du Barn after a short climb.

(2) Continue the descent to Lac Long.

(3) Leave theGR®52to go around the lake on the right (no visible trail), cross the lake's spillway, then cross the grassy area and climb the mound to descend behind it and reach Lac Rond. Take a well-marked trail on the right at the bottom of the valley and reach a small lake. Go around it on the left and continue on the trail that leads to the lake's spillway, from where you can see Lac Petit below.

(4) Reach the lake via the slightly steep path and then, after crossing the bridge, continue along the path to join theGR®52at the Col de Veillos.

(1) Follow the path you took at the start in the opposite direction and return to the car park (S/E).

The access road is indeed rough, narrow and long, but offers beautiful views. The landscape is very different from our other days in the area, with wide open meadows. We climbed up to the pass, had a quick picnic due to the icy wind, then finally climbed to the top of Barn and returned via the ridges, descending to lake number 3.
A beautiful hike that is accessible to many. Do not attempt the ridge in foggy conditions, as there is no marked trail. A stoat put on a show for us among the rocks.

We enhanced this hike by going to the Tête de Barn at an altitude of 2,529 metres. For less than 30 minutes extra, the view becomes even more spectacular, opening up towards the west. However, the estimated walking time of 3 hours and 20 minutes is a little underestimated; it took us at least an hour longer, not counting breaks. Unfortunately, we didn't see any animals, although the car park was almost deserted on a Monday and we had no problems with the road in our city car.

A simple hike that is easy to follow and complete.
In summer, it's best to go in the afternoon to avoid the morning crowds and make sure you can find parking
There is a nice little bar in the car park.

Road blocked by camper vans coming down at 9am!!!
The car park is full, it's chaos.
Definitely not to be done in summer, too many people.

Very beautiful hike. The road leading to the car park is also quite impressive. It takes roughly two hours to reach the first lake. Access to the second lake requires a little extra effort, but you quickly reach the third, which is the most beautiful. We met a couple of hikers who advised us not to go to the fourth lake because it was infested with mosquitoes. So we stayed where we were. We returned via the trail, which is actually a loop and descends all the way down. It wasn't very busy that day (it was a Friday), but according to people we met on the way back, it's a different story at the weekend when it's packed. A superb day out.

On 3 June 2025, there were still many snowfields reflected in the lakes. It was wonderful.
There are five lakes. One of the lakes is hidden on the map by No. 4. The rhododendrons were in bud and will bloom around 15-20 June. Only one chamois crossed our path.
If you want to see ibex, chamois, marmots and flowers, be sure to go to the end of the Gordolasque Valley road and take the short circuit at this time of year. You'll see them all. This circuit passes by the house from the film "Belle et Sébastien" and takes between 1 and 2 hours, depending on how many photos you take. It follows the river on the right-hand side and then on the left-hand side. Enjoy your hike.

I did this walk in September 2024. I saw some chamois, but I didn't see the usual large herd of sheep.
Could you tell me if the Millefonts road will be open from 1 June 2025? Thank you

What a magnificent hike, but it's a shame that the weather turned nasty with the arrival of the fog on the way to the pass and the rain on the way back down.
