Description of the walk

Start___: Les Praz de Chamonix Téléphérique de la Flégère.
Start the hike from the arrival point of the Flégère cable car (stop at the 1st section).

(S/E) From the cable car exit, follow the path towards Lac Blanc.
Start with a short descent along the carriage road that passes under the Trappe chairlift.
At the next junction, turn left towards Lac Blanc. Towards the La Chavanne building.

(1) Turn left, and the climb begins. The path immediately becomes quite steep, leading to an escarpment that can be crossed without difficulty (signposted GR® de Pays du Tour du Pays du Mont Blanc).
All the way up, the panorama of the Mont Blanc massif, the Aiguilles, the glaciers and the sea of ice is breathtaking.
The path is quite steep in places, but never dangerous. A few steps can be high for children.
The first lake appears, and after a final effort you arrive at Lac Blanc (some snow may be present).

(2) After the lake, continue to the Refuge du Lac Blanc.

(3) For the descent, take the path behind the refuge towards the Cheserys lakes, about 45 minutes away; the descent is fairly steep, but well equipped (carved steps and logs). As you approach the lakes, the last hurdle is crossed using metal ladders: one for climbing up and one for descending.
After the lakes, take the first path downhill to the right and join a junction 300 m further on.

(4) Turn right onto the GR® TMB (Red and White markers).

(5) Reach the tête aux vents junction and continue straight ahead to return easily to La Flégère, enjoying the magnificent panorama. Ignore the two paths on either side and return to the junction you passed on the outward journey.

(1) Turn left to take the cable car back to the car park (S/E).

A lovely hike with plenty of sunshine, easy-to-follow signposting and, above all, lots and lots (too many) people. We knew this from the start, but we certainly found it out the hard way! We did it with two children aged 9 and 13 who are used to hiking. The return route is less crowded, however, though the Lac des Cheserys was a bit of a let-down and requires a bit more ‘effort’ due to the ladders. All in all, what we’ll remember is the exceptional view of the Mont Blanc massif and its surrounding peaks……if you’d rather be on your own, don’t go there – or perhaps visit out of season!

A very (too) busy route up to the Lac Blanc mountain hut.
Much more enjoyable on the return leg from the waterfall onwards.
Please note: there is absolutely no shade along the entire route...
You do need to be in good physical shape for this hike.
The big downside: it costs 25 euros per person for the return trip by cable car.
And the same again if you’re having a meal at the refuge.

A lovely walk with views of the glaciers (the Tour Glacier, Argentière, Bossons, etc.) and Mont Blanc. The signposting is easy to follow. It’s very busy, but you might spot marmots and ibex.

Stunning scenery. .We took the cable car. After that, the route is well signposted. There were lots of people heading to Lac Blanc.

A magnificent hike. We weren’t alone, of course, as it’s a major tourist attraction, but I was pleasantly surprised because it was only towards the end of the climb that the crowds became noticeable, and even then they remained quite manageable. It’s a real feast for the eyes and, to top it all off, we saw plenty of ibex on the way back, sometimes just two or three metres away, as they’re used to people being around.

A magnificent hike, but too crowded and noisy around Lac Blanc. We were even disturbed by a drone, even though it's prohibited.

A very beautiful hike. Physically demanding, but never dangerous. The cable car car park is free but very busy. I recommend starting early, ideally before 9 a.m. This way, you'll have fewer people on the trail.
I would not recommend this hike with young children due to the presence of vertical ladders. Pre-teens will be able to manage them without too much difficulty. The views of Mont Blanc and the glaciers are incredible. You get a nearly 180-degree panorama during the ascent.

Hike completed on 6 August... lots of people up to Lac Blanc. Fewer people after that for the Cheserys lakes.
Superb hike with a magnificent reflection of Mont Blanc in the Lac Blanc.

Magnificent hike, a real feast for the eyes. Lots of people up to Lac Blanc, and it gets a bit bumpy on the way up. Then it gets quieter again on the descent to the Chezerys lakes. A short section with ladders requires caution. There was still some snow below the refuge, which was quite fun to descend.
