I wouldn’t say that this is an easy walk. It is quite a climb and the way down isn’t too easy either. It took us 3:45 hours from the Hochjochbahn (bergstation) and back, including Kreuzjoch and two sanitary stops, excluding Zamangspitze. Zamang would have been at least another hour back and forth (including “picture moments”) and we are no beginners. So 5 hours would be more accurate if you wish to take your time to take in the view. The view on the way to the top is the most beautiful so if you would like to enjoy without having to turn around all the time, consider taking the walk the other way around!
