Flying
There’s loads of flights available from all over the UK to Geneva – from there it’s just over an hour’s drive to Saint Gervais if you’re hiring a car.
Best bet is to hire from the Swiss side of Geneva Airport as the car will come with the Swiss motorway tag – if you hire from the French side this is not included!
There are Trains, Transfer Buses as well as Private Transfer Companies running to and from Geneva Airport at regular times – check the schedules and book your train tickets, or bus tickets.
Driving
It’s an easy 8 or 9 hours to drive the 550 miles from Calais down the Péage, and then less than 15 minutes up to Saint Gervais once you turn off the motorway.
