No problems with the route or the guidebook.
The lake itself isn't particularly interesting, but the edelweiss hill is proving to be prolific.
I think you should definitely continue along the path to the right of the lake. It becomes rockier and less easy, but you can climb very high (I turned back at 2,900 metres, but the trail continued) to find a wilder environment (waterfall from the Lamet glacier)
However, this is no longer a family hike but more of an alpine hike. So, some experience and confidence will make things easier.

Walk completed on 8 July 2025.
An easy and pleasant trail with magnificent views of Fort de Ronce and its casemates, Lake Mont-Cenis, Pointe de Ronce and the peaks surrounding Lac Clair. The trail crosses two small ravines blocked by snowfields, which can be crossed without difficulty. The edelweiss were still young above the lake, but already very beautiful. There is no risk of getting lost, as there is only one trail, which is well marked at Fort de Ronce.

Only two signs to indicate the right direction. At the start and at the fort. No further signs after that point, to the extent that you end up wondering if you're on the right route.
Only for experienced walkers.
Two large ravines impossible to cross because they are covered with ice.
Thick clouds obscured visibility. Check the weather forecast before setting off.
Hike unfinished. Disappointing

A beautiful hike, although the appearance and small size of the clear lake are a little disappointing. The view of the fort and the lake on the way down is particularly enjoyable. We went on a Sunday and the lake was absolutely packed, with 95% of the visitors being Italian. A word of advice: if you want to have a coffee or something else between 12:00 and 14:00, don't go to "LAURELMA". They refused to serve us, even though we were standing at the bar. However, next door at "ROCHES BLANCHES", the welcome and service were warm.

Magnificent view of Lake Mont Cenis. Lake Clair, which is also suffering greatly from climate change, is a real gem in a magnificent, wild setting.
No difficulty. A truly beautiful hike.

A magnificent hike under clear skies.
Just one thing to note: when you pass the fort, one of the yellow signs is broken and the direction to Lac Clair is not indicated, contrary to the description. At the crossroads, you need to continue straight ahead, i.e. follow the path that continues eastwards.
Shortly before arriving, the path through the scree is completely clear, so you don't have to walk on stones.
In addition to the spectacular scenery, this hike provides easy access to the high mountains.
On the way down, we spotted a chamois a few metres away on the trail. What a wonderful encounter!

We did this hike yesterday
and it was a bit of a tough climb, but we had a picnic near the stream and then finished the last climb up the scree (much easier than the rest of the climb).
the view is magnificent

be careful, there's no shade and no water to cool off (except for the stream, but you have to cut across the entire mountain pasture by turning left)

a very beautiful hike, thank you

An easy and very beautiful walk. At this time of year, the mountain pasture is covered with flowers, gentians, mountain anemones, etc. The lake is small but very pretty at the bottom of a hollow. The fort was not open, but the exterior is definitely worth a look. On the climb after the fort, you can see more recent fortifications. On the way back, if you have a torch, you can visit a small gallery.

A beautiful hike on the heights of Lake Mont Cenis, which can be admired during the climb. The lake is not visible until the end of the hike.

a beautiful recovery walk, with views of Lake Mont Cenis for two-thirds of the route. Don't forget to visit Fort Ronce. Remember to bring warm clothes if you plan to picnic at Lac Clair.

From Fort de la Ronce, there are beautiful views of the lake and mountains.
Visit the fort for its architecture.
Return via the Sentier des 2000 trail, rich in alpine flora and marmots!
