This is a fast and easy way to get to St Gervais from one of the airports mentioned above and gives you flexibility whilst in the resort. Below a list of major car hiring companies operating at the airports.
Warning - if you hire from the French side of the Geneva Airport you will need to buy a Swiss vignette/ road tax (around €30) and it is a journey to return your car at the end of your stay - so advice is hire from the Swiss side even if slightly more money.
Useful car hire links:
From Geneva Airport to St Gervais (or Le Fayet, the village just 5 mins drive down from St Gervais. A simple taxi ride will complete the journey), several coach services are available. A few recommended suggestions:
Runs about 5 coach trips a day, the L84 service will get you from St Gervais to Le Fayet for a couple of Euros, then this connects with the main service to Geneva for about 28 Euros
Borini runs approx 3 coach services a day, to/from Geneva and St Gervais town centre
Both these very professional companies are part of the same group, run out of Chamonix. The direct Megevexpress is less frequent, and only runs on weekends - but Chamexpress runs every day. Prices are very competitive.
