The White Lake

Lac Blanc sits on a shelf high on the sunny side of the Chamonix valley, directly opposite the whole Mont Blanc massif. On a still morning the lake throws back a perfect reflection of the Aiguilles, the Mer de Glace and the Argentiere glacier across the valley. The climb from the Flegere lift threads past the smaller Cheserys lakes, with a few chained and laddered sections near the top.

Take the Flegere cable car from Les Praz to start high on the balcony. The lake has a refuge if you want lunch with the massif in front of you.

Snow lingers at the lake into early summer and the final approach has fixed ladders. Check it is clear before late June.
