I started practicing last summer and went on a few via ferratas in Switzerland and Italy. The hardest one was in the Dolomites and required climbing knowledge and upper body strength because there were no easy anchors.
The scariest one was in Switzerland, called Mürren where there's a 30m horizontal section with a 400m vertical drop with nothing to hold on to other than the steel cable and some metal inserts in the wall, see https://www.sac-cas.ch/processed/sa2020assetsprod/9/0/csm_15... .
