Annecy to Chamonix Road Trip Guide: Alpine Adventure

Annecy and Chamonix are connected by the A40 motorway, a 90 km stretch that takes about 1 hour 15 minutes without traffic. The route passes through the Arve Valley, with Mont Blanc as its crown.

Opened in stages between 1965 and 1987, the A40 is known as the Autoroute Blanche. It was partly funded by the construction of the Mont Blanc Tunnel. The road crosses several viaducts, including the spectacular Viaduc des Égratz.

The route climbs from Lake Annecy at 448 m to Chamonix at 1,035 m. The landscape transitions from lake and hills to alpine peaks. Mont Blanc, Western Europe's highest peak at 4,810 m, dominates the horizon.

• UNESCO World Heritage Sites: Mont Blanc massif is not UNESCO, but nearby prehistorical pile dwellings around Lake Annecy are.
• Climate: Annecy has a humid continental climate with mild summers. Chamonix is colder with heavy winter snow.
• Things to do between Annecy and Chamonix: visit the Gorges du Fier in Lovagny, the medieval village of Sixt-Fer-à-Cheval, or take a detour to Samoëns.
