Directions from Lyon or Grenoble to Serre Chevalier
If you are driving to Serre Chevalier from either Lyon or Grenoble in winter, we recommend you travel via Chambéry and the Tunnel du Fréjus – an efficient route with very little risk of closure following heavy snow and/or high winds. There are two alternatives which are more direct however:
- the best alternative (although please refer to the disruption in opening times towards the bottom of this page) is to use the recently built Tunnel du Chambon, or
- use the RS1091 (route de secours/security road) which replaces the D1091 near the Lac du Chambon. It is worth noting that this isn’t guaranteed to be open. This is a local transport route to facilitate ease of access for local traffic. Camper vans and lorries must not use this route. No problem for small vans, Renault Traffic-style vehicles though.
NOTE: TO DISCOURAGE NON-LOCAL TRAFFIC USING THE D1091 AND RS1091 (DURING WORK ON THE TUNNEL DU CHAMBON), THE SIGNAGE TO AND FROM GRENOBLE WILL OFTEN INDICATE THAT THE D1091 IS CLOSED. THIS IS NOT ALWAYS THE CASE. THE ROUTE DE SECOURS (RS1091) SHOULD BE OPEN WHEN THE NEW TUNNEL IS CLOSED. DO NOT FOLLOW THE LONG DIVERSION SOUTH VIA GAP.

When is the new Tunnel du Chambon (D1091) open?
Important! The usual route to Serre Chevalier from the north e.g. from Grenoble or Lyon, using the D1091 and the Col du Lautaret mountain pass:
- is temporarily closed from 5 March – 13 July 2017
- re-opens for summer from 14 July – 21 August 2017 (only between 05:00-21:00)
- is temporaily closed from 22 August – 14 December 2017
- re-opens permanently from 15 December 2017.
The above disruption is due to the collapse of the Tunnel du Chambon near the turning for the resort of Les Deux Alpes. A brand new tunnel has been built but is still being decorated/finished.
