Salzburg for the young and the young at heart
Just because something is childlike, doesn’t mean it is childish.
After managing the daily feat of getting up, teeth-brushing, getting dressed and having breakfast, your discovery tour of Salzburg can begin.
The unanimous voice of the children decides where to go, and so you set out towards the Haus der Natur (or House of Nature). What awaits you is a terrific exhibition, a spectacular aquarium and, in addition to the reptile zoo, lots of tiny insects. 
After so much excitement, something a little more relaxing is appropriate. In the Toy Museum (Spielzeugmuseum) parents can be left at the door, so the children can play undisturbed in the workshop.
This is followed by a nutritious lunch consisting of ice cream and cake. After that, take the bus to the Salzburger Zoo. Marvel at as many as 800 animals and 140 species, from wild and rare beasts of prey like wolves and leopards to amusing monkeys to adorable little harvest mice. Not far from the zoo, you can find the Hellbrunn Palace with its tricky water installations, where kids can play and get their parents wet. 
In the evening, there is a performance in the puppet theatre (Marionettentheater), where young and old alike are mesmerized by the magic of the dancing figures. 
After that, the children can bring their tired parents to bed, and spend the rest of the evening relaxing in front of the TV.
