Informations about region of lakes (Como, Maggiore, ...)

[Fiabeschi]

If I correctly understood you are coming from Nice.. So, if it's not closed because of the snow, it would be wonderful to reach Italy by the famous Col de Tende (Menton -> Sospel -> Tende -> Limone Piemonte).

It is a wonderful road and the landscape is worth a trip.

BUT

Pay attention during wintertime. Even if you won't find snow, it is very easy to find slippery and ice on the road. Pretty dangerous indeed, if you don't have AT LEAST winter tires.
