Check out Schloss Hellbrunn
This is a Summer Palace, on the outskirts of Salzburg. It was built around 1615 as a place for recreation, quite literally a ‘fun palace’. It’s a great destination for couples or families, you have access to the palace buildings and literally miles of gardens, within which there are the famous ‘trick water fountains’. A definite must see and less than 30 minutes from Flachau!
