Description of the walk

From the Maurienne valley, go up the Villards valley to the Col du Glandon. Park in the car park at the pass.
It is also possible to start from a car park located at the first of the last four hairpin bends on the road up to the pass on the Maurienne side.

(S/E) From the car park, take the path that runs along the side of the mountain and passes under the Chalets du Col, heading due west. You will soon come to a junction.

(1) Do not take the path on the left leading to Lac de la Combe, but continue straight ahead. The path descends and enters an area where the vegetation is taller.

(2) At the edge of the forest, ignore the path on the left and continue straight ahead. The path climbs and passes at the foot of a rock pillar. These are the eastern foothills of the Aiguilles de l'Argentière.

(3) A trail comes up from below on the right. This is the trail that starts at the hairpin bend on the climb up to the pass and can be used as an alternative starting point. Continue straight ahead and enter the Combe de la Croix. After about 100 metres, a path branches off to the right towards the summit of the Sambuis. Do not take this path, but continue straight ahead to climb up the Combe de la Croix, keeping the torrent on your right.

(4) When you reach the foot of a narrow, steep gully, continue climbing over rocky blocks, keeping the stream on your right. You will soon reach a flat area. One last steep section separates you from Lac de la Croix.

(5) At the lake, go around it to the east and climb up towards the Col du Sambuis in a north-easterly direction.
From here, the trail and markings disappear, but cairns will help you find your way to the Col du Sambuis.

(6) From the pass, descend into the valley towards a small lake (or trace of a lake, as it was dry during the hike) slightly to the right. Lac du Sambuis should appear slightly to the left and then disappear. Head towards it, following the few cairns.

(7) From the lake, descend south-east towards two small lakes in a row. Climb back up south-east to rejoin the Cime du Sambuis trail.

(8) Once you have found the Cime du Sambuis trail, climb up to the left towards Sambuis to reach another small lake.

(9) Descend to the previous crossroads.

(8) Take the Sambuis trail marked in green and black and by cairns. A final small lake is on the right as you descend.

(10) Cross the stream via the metal footbridge and rejoin the path taken on the way up. Turn left.

(3) Continue to the right and return to the Col du Glandon via the same route as on the way up (S/E).

A very beautiful hike with beautiful autumn colours and ibexes as a bonus.
We missed the climb to the Col de Sambuis, but didn't mind too much as the scenery around Lake Croix was magnificent.

A sign at the Col du Glandon indicates "Lac de La Croix 2 hours away": probably by those who happily jump from rock to rock in the moraines, because, as others have pointed out, a large part of the route crosses unstable scree slopes, making it a tiring and "difficult" circuit if you are not comfortable on this type of terrain, which was the case for us (aged 78). Much more difficult than the circuits around and above the nearby Bramant lakes, despite a smaller elevation gain and distance. The helicopter was out to pick up a hiker who had sprained her ankle in the Combe de La Croix, well before the lake. Beautiful lakes and a harsh atmosphere characteristic of the Belledonne massif

A beautiful hike that is quite popular in August, with easy parking. You need to follow the trail closely to make progress, as the cairns between the two lakes are often difficult to spot. I found a wet area with patches of Alpine cotton grass and was able to take some magnificent photos with the Aiguilles d'Arves in the background. Be careful, as the route often passes over large boulders.

A very beautiful circular hike.
Starting from Lac de la Croix towards Col du Sambuis – magnificent view at this spot, but there are few landmarks on the ground. Fortunately, Visorando helps you find your way around.

It was difficult to find the route between the two lakes because there were too many cairns.
Very beautiful hike.

A beautiful route, not very busy on this particular day (the first part up to Lac de La Croix is often very busy) in a high mountain landscape. The gradual climb allows you to warm up before reaching the steeper section below Lac de La Croix. However, several sections involving climbing over boulders may prove difficult for novice hikers.

A beautiful hike, but not marked after Lac de la Croix. Follow the route on your phone and look for clues on the ground (cairns, trail marks, terrain features, other hikers, etc.).
Ibexes near points 7 and 8, which are easy to photograph.
The descent is quite long and tiring.
Enjoy your day with favourable weather.

Superb hike.
Two observations regarding the route to Lac de la Croix:
There is no mention of the fact that almost half of the hike is through scree and boulders. This makes the hike extremely uncomfortable. It does not detract from the beauty of the route, but should be pointed out to anyone who, for whatever reason, is not comfortable walking on scree.
- Unfortunately, a few ill-intentioned hikers have built cairns all over the place that have nothing to do with the route. This makes it difficult to follow at times and can lead to unpleasant detours among the rocks.

A very beautiful summer hike that is not too difficult. Easy to park
The route is good until the first lake, but after that it gets a little complicated

Not too busy

Beautiful scenery but the trail is not very easy to walk on, with lots of scree that slows you down. Like one of the other reviewers, I climbed up to the Col de la Croix, which is worth doing for the view of the Combe Madame valley and the Belledones. No difficulty, good trail, 120m elevation gain. On the way back, I skipped the Col de Sambuis and went straight to the lake, following the numerous cairns. Further down, at the two small lakes (point 7), the cairns stop but you can see the path descending from the Cime du Sambuis in the distance, which you can reach by sight. This section can be tricky in poor visibility, so avoid it in foggy weather. There were lots of people on the climb and at the Lac de la Croix, but no one on the off-trail section.

A beautiful hike in a rocky landscape, which was a bit austere for my taste (especially from the Col du Sambuis).
From Lac de la Croix, which is easy to reach thanks to the clear signposts, we climbed up to the pass of the same name (120 m elevation gain, 35 mins there and back), where the view is magnificent.
We then followed the GPS to reach the Col de Sambuis, as there are many tracks and cairns. When we arrived at the pass, a magnificent herd of ibex, which were not at all shy, were waiting for us, and we really regretted not having our camera. The small lake below the pass was completely dry, but its outline was still easily visible.
From the Sambuis lake, we were unable to follow the GPS track and descended to the two small lakes to pick up the marked trail that climbs to the last lake below the Sambuis peak. This last small lake is not particularly interesting...
All in all, it was a beautiful hike with no particular difficulties

A very beautiful hike.
We set off very early and were alone on this magnificent balcony trail that leads to the torrent. From Lake La Croix, we followed cairns that led us under the Sambuis to a series of lovely little lakes, where we had the pleasure of picnicking in the company of a family of ibexes, who were not at all frightened by our presence. We then decided to skip Lac de Sambuis and descended to the stream to take the balcony trail back. In the early afternoon, we encountered many hikers.
We were familiar with this hike up to the Col de La Croix, but we were doing a round trip and really enjoyed this alternative route.
Thank you for this beautiful hike.

A very beautiful hike, only partially completed between the Col du Glandon and the lake and the Col de la Croix. Return via the same route with a detour around the Carrelet between points (2) and (1).

There are no particular difficulties on this route, even the passage through the narrow gorge from point (4) is fine, although it is impressive. At the flat section just after the narrow passage, the markings are sorely lacking, as it is not clear where the path continues for the final climb before the lake. Keep going straight ahead, then turn right between the boulders and into the bed of the stream that flows down from the lake, using the cairns as landmarks.

The climb to the Col de la Croix from the lake is easy and offers a beautiful view of the Chartreuse in the distance. You can also see a rock with a coat of arms that marked the border between the Kingdom of France and the Duchy of Savoy.

Leave early to get a spot in the car park and avoid the crowds heading up to picnic at the lake.
