couple of hour stop along the bus route from Torino to Chamonix. had lunch and walked the old town for those few hours. really curious & wonderful combination of impressively layered historical architecture, tourist shops and luxury goods emporiums. wonderful water canals run down from the mountain through the town. Aosta seems like one of those places that you could enjoy as a base to see the surrounding region.

fyi – the bus ride to the tunnel that leads to Chamonix is remarkable and you could make it RT if you didn’t want to go through to France. or make taking the tram up Mt Blanc part of the trip.
