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