The official Eisriesenweltgesellschaft site tells everything you need to know
about the caves, including other hiking destinations in the neighborhood.
Fortress and Adventure
As you approach Werfen, you'll see this massive castle atop a steep hill in the middle of
the valley. The fortress was built in the 11th century; today, it offers guided tours and
houses the Salzburg State Falconry Center, which offers daily demonstrations. (The season
runs from early April to early November.)
