Châtel is an easy one and a half hour drive from Geneva airport. Transfers are available from the airport to the resort throughout the year and you can find details of companies offering that service on the Châtel website or contact Magic Transfers: www.magic-transfers.com , but we would definitely recommend that you have a car to make your stay more enjoyable. Hire cars can be booked from the airport - we would suggest you book on the Swiss side as you will be able to use the motorway via Lausanne to Monthey and then pop over the border at Morgins. Just remember to book snow chains!
You can also arrive by train - the closest station is Aigle (with direct train services from Geneva airport) or Monthey, over the border in Switzerland, from where you can get a taxi or on certain dates a bus. Taxis and buses are also available from the railway station in Thonon-les-Bains.
