Bus

It's worth dropping by the bus station for timetables and reservations (highly recommended) or you can book tickets online on Ouibus (www.ouibus.com). Direct services reach Annecy (from €10, 1½ hours, six daily) and Lyon Perrache (from €26, 3½ to 4½ hours, at least one daily).

International routes include the following:

Geneva, Switzerland (airport and bus station) One-way €19, 1½ to two hours, eight daily in winter, at least four at other times. Book tickets through Ouibus.

Courmayeur, Italy Adult/child €15/7.50, 45 minutes, four daily. Run by Savda (www.savda.it), with onward connections to Aosta and Milan.

Car & Motorcycle

  • Chamonix is linked to Courmayeur in Italy's Val d'Aosta by the 11.5km-long Tunnel de Mont Blanc.
  • When the Col des Montets (between Argentière and Vallorcine) is closed by snow, signs will direct you to drive through the rail tunnel. Current conditions can be found at www.chamonix.com.
  • The valley's only car-hire company is Europcar.

Train

The scenic, narrow-gauge Mont Blanc Express (www.mont-blanc-express.com) glides from the Swiss town of Martigny to Chamonix, taking in Argentière and Vallorcine en route.

For destinations around France, including Lyon, Annecy and Paris, you'll need to change trains at St-Gervais-Le-Fayet first (€11.40, 45 minutes, hourly).

Montenvers Station

To reach the cable car to the Mer de Glace, take the scenic cog train to Montenvers (1913m) from the Gare du Montenvers.
