Unlike most of Salzburg attractions, Hellbrunn palace is not in the town center, and goint the by public transportation is not very easy. You have find out where Bus 25 stops downtown. The bus makes several detours. After some fifteen minutes, it arrives at nearby stop; you have to pay attention, because the palace is not visible from inside the bus.
At the palace entrance, you have to join a group for the next tour of the garden and waterworks. The Prince-Archbishop Markus Sitticus built this palace just for pleasure, since he lived downtown. And his idea of fun was to entertain his visitors with very clever automates, occasionally trolling them with water jets. Best attractions: a dinner table where water jets sprout suddenly, drenching everybody, except the person at the table head, namely the Archbishop himself; grottoes that seem to be crumbling; objects poised on water jets; the songs of mechanical birds; an automated doll theater that shows in minute detail the life in a village of its time. Strolling through the gardens, expect water jets suddenly springing under your feet.
