Lovely Castles ,Landscapes and great drive
The most important place to go are the ICE CAVES.Also lovely are the Werfen Castle and not to mention the Sound of Music Tour.I would recommend that you do the tour all by yourself than with the Tours/Agent. The visit to the Werfen Castle was amazing.The great Hawkes and Eagles show you see there is mind-blowing
