Planning to travel to Vienna in mid-June with my wife. Never been to Vienna before although we have visited Salzburg previously for one day, and we loved the scenary. I want to find out if anyone has any suggestion as to where to visit in Austria using Vienna as our base. Is it possible to travel from Vienna to Hallstatt on a one day excursion? or should I be looking to stay in Hallstatt overnight? (not sure how far is Hallstatt from Vienna and the modes of transportation needed). Any other beautiful places I shouldn't miss while travelling to Austria? I am open to any tips and suggestions. Thanks!
