Tour du Mont Blanc Stage 10: Tré le Champ to Chamonix (Ladders and Lac Blanc)

The final stage of the Tour du Mont Blanc leads from Tré le Champ to Chamonix. Here’s the exact location of the trailhead: Google Maps.

For those that started the TMB in Les Houches, this may be your penultimate stage. If that’s the case, read TMB Stage 1: Chamonix – Les Houches for your last stage. 

This is the Tour du Mont Blanc stage with the famous ladders. The ladder section is a protected route with numerous aids (fixed handrails, metal platforms, steps, etc…). These permanent aids help hikers safely ascend steep rock walls. 

In terms of difficulty, it’s relative. If you identify with us (and our hiking experience), then the ladders will likely be easy and fun for you. 

If, however, you have any fear of heights or suffer the slightest vertigo, it’s best to opt for the alternative route which starts close to Col des Montets and links back up with the main TMB route at Tête aux Vents. This alternative trail is summarized in Cicerone: The Tour of Mont Blanc.

The ladders become a bottleneck, so it’s best to start as early as possible to avoid the congestion. 

The TMB twists up the forest and then angles southwest across the northern flank of Vallée de l’Arve. After ascending the protected passage délicat (fixed ladders, railings, steps), the path steeply climbs up to the Tête aux Vents trail junction. From here, you can decide whether to follow the direct trail to La Flégère or the indirect trail via Lac Blanc.

Tré le Champ to TMB Ladders (1:15 hours)

Tre Le Champ to Aiguillette d’Argentiere ladders

The trailhead is located along the Route des Montets road (D1506), just north of Auberge la Boerne. 

The Tour du Mont Blanc twists up the forest and then angles southwest across the northern flank of Vallée de l’Arve. 

At the junction (40 minutes from the trailhead), bear right to Aiguillette d’Argentiere (35 minutes) and Lac Blanc (2:10 hours). 

The trail continues to rise and develops into a balcony path, which leads to a line of crags. The ladder section begins just past the base of Aiguillette d’Argentiere, crowded with boulders. 


TMB Ladders to Tête aux Vents (30 minutes)

Tour du Mont Blanc ladder trail, Chamonix, France

This protected section involves several metal ladders, fixed handrails, and metal platforms, and steps. 

The ladders aren’t continuous. There are stretches of regular trail in between the ladders.

After tackling the longest metal ladder, fixed to a sloping rock wall, the aided climb continues up the mountain to Tête aux Vents (2140 m), marked with a giant cairn.

The views should be absolutely sensational. Low-hanging clouds obscured our views, but I can imagine how stunning it is.

Tête aux Vents to Lac Blanc (45 minutes)

Lac des Chéserys, France

The main TMB trail continues directly to La Flégère (1:05 hours). However, you can take a higher trail to La Flégère via Lac des Chéserys and Lac Blanc

The trail ascends easily to Lac des Chéserys (2240 m). Wrap around the lake and follow the sign to Lac Blanc. 

Ladders to Lac Blanc, France

Climb up the ladder and follow the timber steps to Refuge du Lac Blanc (2352 m).

Refuge du Lac Blanc, Chamonix, France

Refuge du Lac Blanc is a privately-owned mountain hut with 40 dormitory mattresses. They only accept payment in cash. If you eat indoors, leave your trekking backpack outside to avoid scolding.

Lac Blanc is a popular photo motif and always crawling with visitors. From this point forward, you will share the trail with many people.


Lac Blanc to Refuge de la Flégère (1:20 hours)

Lac Blanc to La Flégère, Chamonix, France

The descent to la Flégère is beautiful, but busy.

Follow the obvious trail south/southwest and take in the grand sweep of the giant peaks and domes of the Mont Blanc range. 

Tarn, Lac Blanc trail, Chamonix

Along the way, you’ll pass a few tarns.

We took the Flégère cableway down to the valley and then walked back to Chamonix. By the time we got to la Flégère, my knees were really hurting. So, we decided to descend and not risk injury.

If you’re fit and energetic, keep hiking. Don’t descend early.


Refuge de la Flégère to Le Brévent (3:15 hours)

Rejoin the TMB and continue along the Grand Balcon Sud to Le Brévent. Descend to Chamonix with the cableways. 

You can also descend from Plan Praz (and skip the last stretch to Le Brévent).
