The Col Bas Lakes

A beautiful climb to the mountain pastures and the three lakes of Col Bas through a beautiful forest of larch and Swiss pine trees.
IMPORTANT: This hike crosses an area with wetlands that are rich in biodiversity but very fragile and subject to three levels of protection (APPB, ENS, Natura 2000). It is therefore important to preserve them by refraining from crossing them, particularly between Lac du Milieu and Lac Noir, where you must take care to follow the marked trail.
Reminder: it is forbidden to light fires, swim in the lakes or camp near the wetlands. Dogs must be kept on a leash.

In addition, a chairlift from Montclar arrives at Lac Noir, bringing dozens of walkers to the immediate vicinity of the lake. If you like peace and quiet, it is advisable to avoid the days when this chairlift is in operation. You can find the opening days on the Montclar town hall website or on the "Montclar Domaine Skiable" website.

Description of the walk

Access: from Lauzet-Ubaye, take the road on the left as you leave the village (towards Digne) towards Le Villard - Le Seuil. The hike starts in the hamlet of Le Villard. Follow this road to the hamlet of Le Villard.

(S/E) The path starts at the end of the paved road on the right and is marked as aPR® trail.

(1) A few metres above the last houses, the path splits in two. Take the left-hand path (the right-hand path is for the return journey). A little further on, it climbs steeply through the forest to join a forest track.

(2) Follow it to the left for about 300 m.

(3) Before the stream crossing, take the path that climbs to the right. This path is a little steep with tight hairpin bends but then becomes easier until you reach Lac de la Cabane. This lake only has water in spring. In summer, it can be completely dry but its stony bed is easy to spot.

(4) Pass the place called La Cabane, a shepherd's hut in summer and a mountain restaurant in winter for the resort of Saint-Jean Montclar - Le Lauzet. The path continues along the mountainside on the right above the enclosures to reach Lac du Milieu.

(5) Go around the lake on the left to reach the other end and continue through the pastures and under the ski lifts to reach Lac Noir. Remember that swimming is not allowed.

(6) Return via the same route as on the way there until you reach Lac de la Cabane.

(4) Then take the north bank of Lac de la Cabane on the left and descend slowly through a pretty meadow at the start.

(7) Follow the larch and Swiss pine forest again until you reach a forest track.

(8) Do not take this track but continue along a good path through the forest to catch up with a bend in the track further down, which you follow, passing afirst bend turning to the right.

(9) At the next bend turning left, leave the forest track and take the path on the right, which winds downhill to the crossroads you came from.

(1) Continue straight ahead to reach the hamlet of Villard (S/E).

Well-marked trail, very physical and clear (when I was there), some wet areas are very slippery, so be very careful on the descent. Rightly classified as red

I enjoyed the climb and descent through the forest with its steady gradient. The arrival at Lac Noir was quite dramatic as you can reach it by chairlift. There were lots of families and not much peace and quiet. Once I arrived at Lac Noir, I headed straight for the ridge to reach the Pointe de la Dormilliouse. It would be a real shame not to go there, as the view from the peak is spectacular over the Lac de Serre Ponçon and the Morgon, where I was the day before. I arrived quite late, around 2pm, and the tourists were already on their way down.
Thank you for this hike in the Ubaye, which I know very little about.

hello
the hike was as enjoyable as ever, with beautiful views. The climb is perfect for sunny days because we go up through the forest.

Hello everyone,

On 25 April, PatBolz reported that access to Lac Noir was snowed in. Can you tell me if this is still the case? I'm planning to go hiking there on Sunday 25 May.

Thank you for your feedback

A magnificent hike with a beautiful, steady climb under the trees. The view of the jade-green lake from the hut in spring is splendid. We stopped around the middle lake, which was still frozen at this time of year, and decided not to climb up to the black lake as there was too much snow without snowshoes. The descent is just as beautiful. We followed the directions on the app with geolocation, which was very handy in the snow when the path was no longer visible. Thank you!

Very beautiful hike.
The lake by the cabin was almost dry at this time of year.
The climb was steady and without any particular difficulty.

A very beautiful walk. It climbs steeply from the start (see elevation profile). Once you reach the first lake, after 1 hour 30 minutes/45 minutes of walking, you can take a dip (the first lake is divided in two by the summer heat, so you have to go to the bottom to find a heavenly spot for a swim before continuing the climb to the next two lakes).

Very beautiful hike. For your information: all the trees that fell this winter and were blocking the trail have been cleared. The route is now clear. At the Point (8), when you arrive at the large platform, just take the marked mountain bike trail on the right.

The route is very well marked for the climb up to the last lake but very poorly signposted for the descent! There was a lot of snow ⛄️ when we arrived at the last lake. We only came across one group of three hikers in six hours of walking 🚶
There were also lots of fallen trees on the paths both on the way up and down!
Good physical condition required
Superb view upon arrival at the lakes

Beautiful hike. The signage on the way there is perfect. However, on the way back after the lake at the hut and until the forest road junction, it is rather poor. There are no signs before or at the junctions! Fortunately, I had my GPS.
The return trip on this side is longer than the ascent route.

Route starting from LAUZET on UBAYE, climbing towards Le SEUIL, then following the description in reverse to Lac Noir (not including the walk around the lake). Descent to the lake by the hut via a different route (below the chairlift), then from the hut down to LE VILLARD. Descent to LE LAUZET via the path through the woods.
A very beautiful hike in autumn. Beautiful views.
Full tour for experienced hikers only: 20.6 km - 1,526 metres of elevation gain - walking time 6 hours 15 minutes, fairly steep slopes (ascent and descent) with a few "flat" sections to catch your breath

Hello Dezei, and thank you for your feedback.

You are right: the combination of distance and elevation gain means that this hike should be classified as difficult. I have just made the change.

Easy route to follow thanks to the signposts. The middle lake is magnificent. For the more adventurous, you can continue from the lake to the summit of Dormillouse, with an additional 300 m of elevation gain
