Tips and advice
The best entry and exit airports are Geneva and Nice. Whilst Geneva is in Switzerland, it is only several kilometres from the French border and the airport is much better served than French regional airports. Nice is France’s second busiest airport with regular flights to many global destinations.
Both airports have all the major car rental companies and because of Geneva’s proximity to the French ski resorts, SUVs are available for hire. Most of the routes driven in this article are similar to our backcountry gravel roads and can be driven in a hire car. Two strong pieces of advice would be to buy an aerosol t ype puncture repair kit from a service station and drive slowly. I had one puncture on this trip and most hire cars only come with an “emergency” spare.
The Alps hold a lot of snow and you want great sunshine days for your trip. The best months for this trip are August and September. Any earlier and there is the risk that the saddles/ passes won’t yet be clear and any later, the weather will be unstable.
