By Air
By Air
Geneva - approx 2 1/4 hour transfer. GVA has excellent bus/shuttle links with the most flights & hire car options.

Grenoble - approx 2 1/2 hour transfer. GNB New option as low cost carriers now flying there from the UK.
Lyon-Saint-Exupéry (Satolas) - approx 2 1/2 hour transfer.

Chambéry - approx. 1 1/4 hour transfer. CMF is the closest but has few flights. As a smaller airport it is susceptible to close in bad weather and your flight could be diverted elsewhere.
For checking cheap flight options we recommend using SkyScanner which checks all budget airlines going into a particular airport, and gives you the best prices and shows alternative times/dates. When comparing costs always check on baggage allowance policy for skis and ski boots.
Don't forget about the scheduled carriers, Swiss have some great deals and BA has loads of flights as well. They also have a more generous baggage allowance and will often be cheaper if you are bringing ski equipment.

Eurostar direct service 
  • Relaxing, fast and convenient direct service to Moutier, rarely delayed.
  • Short check in times, Daytime or overnight services.
  • Probably the fastest way "door to door"  to Mottaret at around 7 hours from London.
  • Short 30 minute transfer up the mountain by taxi (book in advance) or bus.
  • If booked early can be very cost effective combined with cheaper transfer costs.
  • No charge for bringing skis and extra baggage
We recommend the day train going out and the overnight return giving you 7 days of skiing and missing the Saturday changeover traffic, with clear slopes on your last day.

Eurostar - French Rail
Another option is to take the Eurostar to Paris Gare du Nord and then a taxi / RER to Paris Gare Lyon or Paris Austerlitz for TGV services to Moutier. There are many more options this way and it is generally cheaper than the direct service but does require a change of trains. One great option is to get an evening Eurostar to Paris and an overnight sleeper to Moutier. Opt for the the First class sleeper service, it is only a bit more and has 4 berth carriages instead of 6.
