Just curious if anyone here has done that. I have watched the YT videos on it and it looks like total fun. My wife and I watch them and I tell her that is on my bucket list. But she isn't into nudity, so that probably won't happen. But that would be one hell of a vacation. Tell all our family and friends that we hiked part of the Alps in the nude with 30 other people.
I've not done that specific tour but have done many of the same/similar Alpine hiking trails in Austria nude as well as Alpine hiking trails in Switzerland. I live in Switzerland and it's easy to strip off and hike nude in the mountains here.
