I love travelling to Austria and have been on some nudist walks in the mountains [finished off by a visit to the local nudist section of the lake].
My favourite was a trip on 3 cable cars [dressed] but then a 2 hour hike up to the top [of the Zwölferkogel] and back down. I didn't encounter anyone until I put my rucksack down to get dressed again and a guy came past and just said hello.
I have lots of photographs of the lake below and the other mountains. One has even been the wallpaper on my PC at work and no one knows I took it nude 😉
I, too, have walked some five miles naked in Austria. In the woodland/forest near Jenbach, up over Rottenburg and towards Buch bei Jenbach - not forgetting the secluded waterfall there!
The river at the top of Wolfsklamm near St Georgesburg is more public, but can be refreshing on a sunny Summer day! I noted naked sunbathing on the shores of the Achensee too.

It's so much easier there and a wonderful experience.
