This route, while fantastic and spectacular, should be removed from Komoot. It's no longer visible, the steps are barely visible, and at too many points it's truly irresponsible and life-threatening!

Warning! Update 2025: Do not hike this trail! The descent from Piskerra no longer exists. The ascent to Piskerra is also not easy and not for beginners. The same applies to the broken steps. It took me three hours to complete the entire hike, twice as long as planned, and at times I was in mortal danger. No joke.
