We are travelling after Easter to Munich and southern Germany as well as Salzburg and hopefully to Hallstatt Austria. What kind of weather should we expect. We may also try to take in a trip to Zugspitze. We are also trying to decide on whether to rent a car or just travel by train. We are arriving at Munich Train Station on 4/28 and leaving Europe on 5/3 via Munich Airport.
Any suggestions are appreciated.
