Built in the 17th century by bishop Markus Sittikus, this castle is mainly known for its ingenious trick fountains and water-powered figures. When the tour guides set them off, expect to get wet! Admission includes a tour of the baroque palace. Other parts of the garden (without fountains) are open year-round and free to visit.
Eisriesenwelt HöhleThe world's largest accessible ice caves are in the mountains near Salzburg. These Eisriesenwelt Höhle (Giant Ice Caves) house elaborate and beautiful ice formations. Take warm clothes because - surprise, surprise - it gets cold inside. The tour lasts 75 minutes, so you need to be reasonably fit.
KuenringerburgHigh up on a hill, where it commands a marvellous view of a curve of Danube River, is the ruined castle of Künringerburg, where King Richard I (the Lionheart) was imprisoned from 1192 to 1193 for the heinous crime of insulting Leopold V.
Hohe Tauern National ParkThis park covers over 1786 sq km (690 sq mi), making it Europe's biggest. At the heart of this protected oasis of flora and fauna (including marmots and some rare ibexes) lies the 3797m (12,454ft) Grossglockner, Austria's highest mountain. The highway through the park, the Grossglockner Hochalpenstrasse, is one of the world's most scenic.
Krimml FallsThese triple-level falls are an inspiring sight and attract hordes of visitors in summer. In winter, the slopes above Krimml village become a ski area, and the falls a static lump of ice. The falls' combined height is 380m (1246ft), over three main sections connected by a twisting river and rapids. The trail alongside them is steep in parts, but rewarding.
