Geneva Airport is partly located in the Swiss canton of Geneva. Curiously, the rest of the airport is located on the Swiss-French border.
Geneva Airport is one of the key transport hubs for tourists heading to the ski resorts of France and Switzerland. So, you can get to Val d Isère from Geneva airport in several ways:
1. Private transfer in a comfortable car from Geneva airport to Val d'Isere. The france-transfer.com company offers to order a car of any category.
2. By train from Geneva airport you can get to Val Dieser with only 2 changes in Geneva central station and in Chambery, but the train will take you only to the Bourg Saint Maurice station where you will need to make another change to the bus. The advantage of this type of transport is that trains run 5 times a day and it is an economical and affordable transfer.
