If seeing the sights is on your list of things to do, head to Hellbrunn Palace— just one of the landmarks located 2.8 mi (4.6 km) from central Salzburg. You could also start your cultural experience by heading over to the museums in the area.
If museums are on your list of things to see, you might want to browse the collections at Hangar-7 in Maxglan. It's also full of great shops and restaurants, so you can spend the afternoon having a wander. If you want to see more of the museums in Salzburg, Mozart's Birthplace isn't far either.
