The rack railway, built in 1912 by Otto von Steinbeis, is the oldest working rack railway in Germany. Since its renovation in the early 1990s, it has been worked by modern railcars that have reduced journey times from over 50 minutes to about half an hour. Near the rack railway mountain station is the Wendelstein Cave with several stalactites and stalagmites, and which contain ice until well into the summer months.
