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 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.

As the signs were no longer posted in October, we took the wrong route. We need more signs because following the white lake sign is not valid.
Otherwise, it was a lovely hike with magnificent scenery.

A very nice hike, a must if you're going to Chamonix.
I didn't take the 2nd cable car so I could do a loop with a bit more difference in altitude.
Lots of people were there that day for the Lac Blanc, but fewer for the Lac de Cheserys.

A great walk in a magnificent setting!
Very well signposted trail.
Between Lac Blanc and the Cheserys lakes, there are some tricky sections for small children.

Option to eat at the Lac Blanc refuge.
