A short flight of around an hour and a half takes you from Britain to Geneva, our nearest airport. Once at Geneva, you are just 100 km from the chalet, via (in approximate order of convenience and expense) hire car, airport transfer, bus, or train.
Try for a window seat as the views of the mountains are lovely. Make sure you check which side your flight arrives and departs from. Most are from the Swiss side (Secteur Suisse) but occasionally you do get them (notably with Easyjet) from the French side (Secteur Francaise). There is a short walk between the two sides which is not as well signposted as it might be, so it’s best to check – and if you’re hiring a car, the same applies – see Car Hire for more on this.
The terminal is generally very efficient, as you’d expect. It has good facilities including an excellent nursery and extensive duty-free shopping. Sterling, Euros and Swiss Francs are accepted equally within the airport.
