1) What is the best time of year?
2) Snow chains are compulsory on certain Swiss roads. How will I know which ones? How will I fit snow chains?
3) What happens if I break down and I can't speak enough French, German, or Italian?
I did the Route des Grandes Alpes at the end of May, and the Col d'Iseran was closed so had to do a BIG detour through the Frejus tunnel which cost 40 euros !
So imho June is definitely the best month, still lots of snow around and some decent sunshine. No traffic apart from a few bikes.
As Gambalunga says, no need for chains if theres no snow on the roads.
Your breakdown cover will be english speaking.
