The Leutasch Gorge (German: Leutaschklamm or Leutascher Geisterklamm) is a gorge near Mittenwald and in the Bavarian-Tyrolean border area through which the Leutascher Ache river flows. It is very steep-sided and was not opened to tourists until 2006. To do this a 1.4 million euro, EU-supported, Austro-German project was undertaken to build steel walkways and bridges over a distance of 970 metres. With a total length of 1,650 metres it is the longest accessible gorge in the Eastern Limestone Alps. The gorge was opened on 24 May 2006.
