If you travel to Tignes by car, please note that Col du Petit Saint-Bernard is closed during winter. Some GPS routes will try to guide you this way. To avoid it, you can enter Albertville as way-point.
There is a parking lot right across from the building (approximately €75 per week). Free parking is available in Tignes les Boisses. There is free bus transfer from Tignes les Boisses to Tignes Val Claret in the daytime.
