Hi Sasha,
We did two driving "Christmas Market" trips in early Dec. 2010 and 2013. Flew into/out of Munich both trips. We picked up and returned the car at Munich airport. Visited by car: Berchtesgaden, Bad Reichenhall, Salzburg, St. Gilgen, Hallein, Schladming, Ramsau am Dachstein, then moved on to Hall in Tirol, Innsbruck, Rattenberg and then over the Italian border to Sterzing/Vipiteno and Brixen/Bressanone. We also enjoyed a day cruising the Wolfgangsee visiting the markets in St. Gilgen and St. Wolfgang. We parked in St. Gilgen and hopped on the ship and cruised to St. Wolfgang. Very nice way to spend a day. We missed a stop at Strobl.
We have been to most of these before, but during the Christmas Markets it was like visiting for the first time all over again. Simply magical. Christmas lights, decorations, trees, stalls lining the old town selling all sorts of goods, hot drinks, food, the smell of roasting chestnuts, fires to warm up by... the holiday atmosphere is incredible.
We had a few days with some snow on both trips, but roads were kept clear and the snow wasn't an issue at all. Temps were basically what we experience at this time of year in NYC area. During our stay in Ramsau am Dachstein, while there was nearly a foot of snow already on the ground, the sun was so strong we didn't need to wear jackets during the day.
