The Krimmler Ache river

Have you seen this river? Have you seen this valley? That clear water? Isn’t it a dream to go flyfishing there ? The Krimmler Ache is by the town of  Mittersill in Austria, not to far from Salzburg, it looks like heaven. I want to go fishing the Krimmler Ache, I want to be there! When is sprong coming back again?
