What are the must sees for a one day trip to Salzburg.
climb or ride up to the castle for a good view.
All in or near the center: Castle, Churches, Graveyard, Gardens, Fountains, Music (even the street music is great), Brewery, view from one of the pedestrian bridges on the way to the Brewery.
St. Peter Stiftskeller, a restaurant in old town, was first documented in the year 803, and takes its place as the oldest Restaurant in Central Europe. I had lunch there which was wonderful and the prices were very reasonable. If you don't want to dine, at least pay a visit. It is absolutely beautiful, downstairs in the restaurant and upstairs in the ballrooms. I have also enjoyed walking through Mozart's birthplace and home which is also in Old Town. Have a great visit!
