Contrary to what the guidebook says, I think that technically the final section is a proper technical climb.
A steep slope over scree before finishing with some scrambling (admittedly easy... but where a fall is not an option... and it’s easy to twist an ankle on the descent, especially if you’re tired).
... especially as at this altitude, there can be ice even during so-called warm periods.

Although the elevation gain isn’t huge for someone who’s reasonably fit, if that person is sensitive to altitude and not acclimatised, it can quickly become very difficult.

... so I’d just advise not to take this guide too lightly.

It’s a shame not to go via Lac du Grand Ban and the legendary Pointe des Cerces; it doesn’t add too many kilometres or much elevation gain (though Pointe des Cerces is a snowier area).

All this to say that I did it last year and it’s now one of my favourite routes... but be careful if you’re not used to tackling 3,000-metre peaks; you might be taken aback by the snow conditions (which can change drastically from one week to the next), the scree and the altitude.

Incidentally, via the Grand Lac, the route also looked nice and shorter – isn’t that better for people who only do the Grand Galibier?

And I can confirm that at the Col du Ternier, it’s easy to get lost: cairns everywhere pointing towards the eastern summit of the Galibier... the GPS track really came in handy for quickly correcting my course... because after that, you can’t carry on to reach the western summit... you have to turn back (in theory).

We set off from Les Mottets, a superb hike (thanks to the weather gods that day)! 360° views at the summit, fantastic! A long climb, certainly, but without any difficulties (see detailed guide) and superb views all day long. Be sure to turn left at the Termier pass and follow the path with cairns and blue markings to the top. We descended via the Plan de la Ja (path to the left/north-west at the Ponsonnière pass), which was simply magical and very wild. The path is clearly visible (orange dots help you find your way). We came across hundreds of sheep and the shepherdess, which was wonderful, as well as a beautiful weasel in the valley where the Ponsonnière river has its source! And we got back to the car right on time. A truly magical day. Thank you to the author for the detailed guide.

Thank you for this very detailed guide. We drove along the track to Le Mottet, at the foot of the path leading to Lac des Cerces. This saved us a very welcome 200 metres of elevation gain. There was plenty of space in the car park at 8.30am, and the forecast was for a beautiful day. There were four of us, all in good physical condition and aged between 17 and 51. The climb took us 3 hours and 15 minutes without any strain – we decided to take our time at the summit and at Lac Blanc and further down the descent (perhaps a two-hour break in total). We were back at the car eight hours after setting off. I mention this because it might be a good idea to adjust the 10-hour estimate in the guidebook – it had discouraged me when I first looked at it.

Second attempt (see previous post, September 2023), this time successful, at this legendary peak in the region.
Practical information: the road between Plan Lachat and Les Mottets was badly damaged in spring 2024 and therefore impassable. On 30 July 2024, it had been repaired and I was able to drive along it.
There were few people in the upper car park at 6:45 a.m., even though it was the middle of the holiday season and the weather was beautiful.
The climb to the Col de la Ponsonnière via Lac des Cerces (where bivouac tents had sprung up) is magnificent, easy going and shaded for most of the morning.
After the pass, the path is clearly visible and marked with cairns.
At the Termier pass, with a view of Lake Termier slightly below, you have two options.
- 1) On the right, a large cairn of purple rocks marks a clearly visible path in equally purple soil that heads off to the right among the rocks. This path is shorter, but it passes through rocky outcrops that must be climbed without any real landmarks.
- 2) On the left, a path that is much less visible at first descends slightly to go around Lake Termier on the left and then climbs back up the scree of the large valley that leads to the summit via a clearly visible, gently sloping path dotted with small cairns. In any case, you should stay as far to the right of this valley as possible, along a large rocky outcrop. This route does not present any particular difficulties compared to the one described above (1)

Paths 1 and 2 merge further up into a single path well before the summit peak.
I set off from the Termier pass, taking path (2) at the same time as a group that had chosen path (1), and we arrived together at the fork...
However, I imagine that path (1) is interesting at the beginning of the season when there is still a lot of snow at the bottom of the valley and around Lake Tremier, as it avoids this lower section.

Continue up this valley to the blue markings (lines, dots and sometimes arrows) that are clearly visible from a first small couloir to climb on the right. An isolated blue dot a little lower down had misled me.
You can put your poles away, as you won't need them again until you reach the top...
After a few harmless acrobatics, you will reach the summit, where you can enjoy an exceptional panorama.
There are numerous ibexes just below the summit, roaming around on small ledges.

Thank you for this guide

Well, that sunrise must have been fabulous. We were lucky to have such good weather this September. Thank you for your feedback.

A beautiful hike. I camped in Ponsonniere, then resumed my route with 800 metres of elevation gain remaining at 4:00 a.m. with my headlamp so as not to miss the sunrise from the summit!
All the magic of the mountains was right there in front of me!
I did this hike on 24 September 2023.
It was very windy, with some snowfields that were perfectly passable.
As I approached the summit, I followed the blue dots closely, otherwise a bit of simple climbing is to be expected.

As the summit trail is not shown on the IGN map, I have just updated the route of this trail from Col Termier using the Open Street World map currently available on the website.

Hello,
For the section between the Termier Pass and the summit, I recorded the route during the hike on the descent, as it does not appear on the IGN map.
However, recorded tracks can sometimes be inaccurate due to GPS satellite connections being disrupted by rocky outcrops, etc

From the Termier Pass, the description is more than sufficient to reach the summit. As indicated in the description, you had to take the path.
It's a shame you didn't reach the summit because at 3,150 m you were only 78 m away from the top, knowing that at this altitude you were supposed to already be on the summit bastion.

Beautiful weather and warm temperatures
Departure from Les Mottets. Long approach walk to the Col de la Ponsonnière via the pretty Lac des Cerces.
At the Termier pass, do not follow the path to the right marked by a large cairn of purple rocks, which seems to lead to the eastern summit. A clearly visible path below skirts the lake of the same name on the left (and not on the right as indicated by the GPX track)
After Lac Termier, at the foot of the combe between the east and west summits, there is still no sign of blue dots.
A few cairns indicate a path through the scree towards the left side of this valley (as indicated by the GPX track), while a visible path climbs steeply to the right of the valley.
I followed the GPX track to the left, but after an hour, at 3,150 m, there were still no blue dots, no more cairns, and it was impossible to access the clearly visible passage at the foot of the summit.
Perhaps a recent large rockfall had filled the passage with large boulders?
So I had to climb down some very sharp rocks...
I returned to Lake Termier, but it was now too late to take the steep path on the right side of the valley, which must be the right one since I saw a hiker coming down it.
I'll come back, and maybe this time I'll reach the coveted summit!

You can start from the Mottets car park (2,140 m). The track is accessible without a 4x4, but the elevation gain is noticeable, especially on the way back at the end of the day!

Wonderful hike, thank you for the description!

Thank you for submitting your review.
As you just mentioned, you need to take the right path to reach the Termier Pass, then descend towards Lake Termier before starting the climb
to the summit.
As I mentioned in the paragraph below the map entitled "During the hike and nearby",
, is to follow the first blue dots that lead off to the right on the rocks on the climb up to the Termier pass.
(Follow the path to the pass.)

As you so rightly say, the TD rating is only due to the length and elevation gain, provided you do this route at the right time of year, i.e. after the snow has melted. "Generally from 15 July, or in some years from the end of July to 15 September."
