Once the summer palace of the Archbishops of Salzburg it has lots of clever fountains and pretty gardens. When you take the tour stand next to the guide otherwise you will get wet. Hellbrunn is surrounded by vast gardens, including a good children's playground with swings and flying fox (zip wire), and a cold wading pool, and is a perfect place for a picnic or a long walk through the green. In the Steintheater (Stone Theater), the first opera in Middle Europe was conducted. Children and adults alike are amused. There is an excellent and substantial zoo within the grounds.
The zoo is in south Salzburg and is open 365 days a year. It also has a petting zoo for children. There is a restaurant on site serving traditional Austrian dishes.
Festung
On top of a mountain, the Festung offers breathtaking views of Salzburg and the Alps. One area of the fortress offers visitors the chance to look down on a field below to find only one house, the executioner's residence. It was believed to live anywhere near the executioner was bad luck. Inside the fortress is a museum of medieval weapons, life on the fortress, and torture instruments. Public concerts are often held here in the evenings, reservations are recommended. On nights with concerts, it is possible to remain within the walls past dark. To avoid the vertical hike up to the fortress, a funicular is available to ride, for a fee. It's the oldest funicular in Austria.
Petersfriedhof
Perhaps most remarkable are the small catacombs (€2 adults, €1.50 children) carved into the nearby cliff side. Climb up for a couple of small chapels and a nice overlook.
Salzburger Dom
In Cathedral Excavations Museum you can see objects excavated from a Roman villa and foundations of the west towers of the Romanesque cathedral both of which stood in the area of today's cathedral.
