I'm pondering a September trip to the Alps, I fancy driving to Chamonix, then driving over into Italy to Aosta, then maybe to Switzerland at Saas Fee.
Has anyone any recent experience and/or guidance on hopping between the three countries? I can't find guidance about restrictions, for say, France to Italy, or vice versa. Or Switzerland.
What would be the situation if I traversed, for example, the Matterhorn from Italian side to Zermatt?
Any pointers or experience would be welcome.
