This bus tour is well worth leaving the city for when you get to visit the salt mines for which Salzburg is named. The four-hour tour travels into the Bavarian Alps to the 500-year-old salt mines of Berchtesgaden. Learn about the salt mines and the history of Salzburg with a two-hour underground tour that includes slides, train rides and boat rides. You’ll have a chance to take home salt from the mines, as well. Dress or bring warm clothes, as the salt mines can get quite chilly.
