Lac Blanc
Ride the Flégère lift out of Chamonix and a two-hour balcony path delivers you to Lac Blanc, the tarn whose still water doubles the entire Mont Blanc massif — one of the Alps' great mirror shots.

Why go
The lake sits at about 2,350 metres on the Aiguilles Rouges side of the Chamonix valley, facing the Mont Blanc massif across the void. Two small tarns, a stone refuge and a great deal of granite; the point of the place is what stands opposite, a wall of glaciers and spires filling the southern horizon. Snow lingers late here, and the water is often part frozen into early summer.
This is a half-day outing rather than a destination in itself, best folded into a week based in Chamonix or Argentière. The usual approach takes the Flégère lift and follows the balcony path, though walkers can also come up from Tré-le-Champ on a longer route with fixed ladders. Late June to early October is the realistic window. In poor visibility there is little reason to go, since the view is the whole reward.

From our guides
The trail is rocky in places but never technical, and the little refuge at the top sells omelettes and views in equal measure. Go from late June once the snow has cleared, and start early; by noon the reflection is fringed with tripods.

Things to do
-
The reflection at first light
Still air early in the morning turns the tarn into a mirror of the massif. Wind usually ruffles the surface by late morning.
-
Grand Balcon Sud
The traverse along the Aiguilles Rouges links Flégère and Planpraz with almost no climbing and a constant view of Mont Blanc.
-
The refuge by the water
A simple mountain hut beside the lake serves hot food, and sleeping there gives you the place to yourself at dusk and dawn.
-
Ladders from Tré-le-Champ
The longer walk in climbs a rock step on fixed metal ladders. Straightforward, but not for anyone uneasy with exposure.
-
Aiguilles Rouges nature reserve
The whole slope is protected, and ibex, chamois and marmots are often visible from the path in the early hours.
-
Aiguille du Midi
Back in the valley, the cable car climbs to 3,842 metres for the other half of the Chamonix view, this time from inside the massif.
Getting there
-
Fly to
Geneva (GVA)
Nearest airport to Lac Blanc, about 66km away as the crow flies.
-
Then
To Chamonix
About an hour and a half by car or shared shuttle from Geneva (GVA), the standard gateway; Annecy (NCY) is a similar drive but has few flights. Buses run direct from Geneva airport to Chamonix.
-
On the ground
Getting around
Take the Flégère cable car from Les Praz just outside Chamonix, then walk the balcony path for around two hours to the lake. A steeper approach on foot from the valley floor is possible without the lift.
Public transport: Good. A train line runs the length of the valley and free local buses for guests reach the Flégère lift station.

Where to stay
Chalets and chalet hotels, mountaineering-style guesthouses, apartments and a few refuges on the mountain itself. Chamonix is one of the few Alpine towns with year-round hotels.
-
Best base overall
Chamonix centre
The town has the widest choice of rooms, the gear shops and the bus network that reaches every lift including Flegere. Parking and summer traffic on the main street are grim.

Closest to the sights
Les Praz de Chamonix
A quiet hamlet a couple of kilometres out, sitting directly at the foot of the Flegere cable car, so the Lac Blanc walk starts on your doorstep. Choice of restaurants is limited.

Best with children
Les Houches
Down valley, greener and calmer, with gentler walks, a lift of its own and family hotels at lower rates. You take the free train or bus into Chamonix for anything bigger.
Find stays in Les Houches -
Quietest
Argentiere
A proper mountain village at the top of the valley under the Grands Montets, with climbers' hotels and less bustle. Buses run frequently, but evenings are much sleepier.
Find stays in Argentiere
Worth knowing before you book: July and August are the busiest weeks of the year and the valley sells out. The Flegere lift only runs in season, so check opening dates before planning a late June walk.

Good to know
- Timing
- Snow can block the path until late June and returns in October. Check lift and trail status before committing to the walk.
- Pack this
- Proper walking boots, a windproof layer and water. The refuge sells food, but the exposed ridge is cold even in August.
- Crowds
- The route is popular. Taking the first lift up, or staying at the refuge, buys you an hour of quiet at the water.
- Altitude
- The lift saves most of the climb, but you are still above 2,300 metres, so take the ascent gently.
- Weather
- Afternoon storms build quickly in summer. Aim to be back at the lift by mid-afternoon rather than pushing on.
