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 really lovely walk with some fairly steep, challenging sections along the stream; a wonderful reward at the summit in the form of ibex, which are a regular sight in the area and not at all shy.

A lovely walk, with a view of a female ibex and her young at point 4. Be sure to stay WELL to the left of the stream, even though there is a cairn on the right-hand side of it.

A lovely walk. Beautiful scenery and wildlife (ibex, marmots, etc.). There were still a few patches of snow, but nothing you couldn’t get past.

Hello everyone,
A wonderful hike that I’d highly recommend during this spell of hot weather.
There are some lovely sections through the snowfields.
Bear in mind that from Lac de la Croix there are cairns dotted about everywhere, but if you follow the signposted directions, you’ll find your way back onto the right path. We were lucky enough to spot plenty of ibex and vultures.
The round trip to the small lake between markers 8 and 9 is well worth the detour. The footbridge (marker 10) was covered by a snowfield, but crossing the stream is easy – either by hopping from one rock to another or by taking off your shoes (a refreshing experience guaranteed).
Magnificent views across all the mountain ranges.

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 beautiful hike, including a return trip to the Col de la Croix.
Be sure to follow the trail markers and cairns from Lac de la Croix.

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
