Is August Right for You?
Weigh the advantages and considerations before booking
- + Glacier hiking season peaks. Mer de Glace and Bossons glacier walks are safest and most accessible. Guides run daily departures. Book early.
- + Paragliding thermals are most reliable. Afternoon updrafts from the valley floor create 20-30 minute flight windows. You soar over Chamonix town.
- + Wildflowers carpet the high alpine meadows above 1,800 m (5,900 ft). Spectacular on the Grand Balcon Sud trail. Go early.
- + Mont Blanc summit attempts wind down. Fewer crowds on lower elevation trails. Better availability at mountain refuges. Enjoy the quiet.
- + Local food markets overflow with August produce. Wild blueberries from the slopes sell at the Tuesday/Saturday market by Église Saint-Michel. Taste them.
- − Afternoon thunderstorms roll in around 2 PM 40% of days. They gather fast over the Massif. Hikers above tree line get stranded. Seek shelter.
- − The Aiguille du Midi cable car queue stretches 90+ minutes by 9 AM. Even with timed entries, you're waiting in direct sun at altitude. Bring water.
- − Valley trails turn dusty and loose. The famous Petit Balcon Nord becomes a slip-fest of gravel and horse manure from tour groups. Watch your step.
