Description of the walk

To get to the start: from Notre-Dame-de-Bellecombe towards Les Saisies, reach a wide right-hand bend with a platform on the right-hand side. At the entrance to this, turn left towards Les Excoffonières - Plan Désert (lake).
Follow the small road to the end and park near the lake.

(S/E) Continue along the track that passes under the chairlifts and joins the entrance to the farm.

(1) Ignore the access road to the farm and head for the next fork on the ridge via a fairly steep climb.

(2) Continue to the right and enjoy the view of nearby Lac du Gui. After a short climb, the track curves to the right and continues almost horizontally to Mont Rond.

(3) After enjoying the view, return to Lac du Plan Désert via the same route (S/E).

We made a variation to this itinerary that we found interesting:
Parking at the Plan Désert lake car park, we walked to the foot of the chairlift and the small bar-restaurant. There, a sign points to Le Stomu le Chardonnet. We followed this good, slightly downhill, shaded path that runs along the left bank of the Nant du Milieu stream.After passing a sheepfold (elevation 1,427 metres on the IGN map), we began the climb up to Mont Rond (signposted at this intersection) via a wide path that first passes under the Mont Rond chairlift before reaching the summit. Then follow the "chemin des Gueux" to reach Lac du Gui and descend via the track described in the original hike itinerary to return to Plan Désert.
A nice little loop of about 7 km with the advantage of climbing almost entirely in the shade if you set off in the morning.

The climb is steady on a road.
There is a beautiful view from the top of the round hill
The restaurant is closed on Mondays.

Family hike with a climb up a rocky mountain path with little of interest
Lake Gui is more like a large pond. However, the view of Mont Rond is magnificent, with an alpine chalet that doubles as a restaurant/bar
For the descent, we decided to cut through the forest (there is a path to the right of the ski lifts) to reach Lac du Gui and finish on the same path as on the way up
We had a picnic by the lake at the start of the hike, which was a good warm-up for the hikes to come

A very beautiful, well-marked hike. Breathtaking views all along the way. We even saw marmots.
I highly recommend it.

Beautiful views from both the Plan Désert car park and the summit of Mont Rond: a 360° panorama! There are also numerous picnic tables.
And a little later in the season, you can buy mountain cheeses and charcuterie at the farm located along the route.
Abundant flora all along the way.
A beautiful, easy hike.

One small downside regarding walking times. The climb to the summit was advertised as taking 2 hours and 25 minutes, but in fact it only took me 1 hour and 15 minutes, following the route perfectly... and I'm no sprinter.

Very pleasant hike
A nice spot at the start and finish for a picnic.
At the end, a 360° view that is sure to take your breath away on a sunny day.
An easy climb, even for people aged 75 and over.
I would love to do this hike again in the sunshine.

The appeal of this walk is to enjoy the views offered by Mont Rond: Mont Blanc, of course, Aravis, Beaufortain and the peaks of Espace Cristal. We extended the walk to Mouille Froide (from there, it is possible to return via the valley). The initial climb is quite steep. Ski lifts are everywhere. On this sunny Sunday, there was a great atmosphere with picnickers around Lake Plan Désert. There were lots of herds (even free-range pigs!) and goat's cheese for sale shortly after the start.
