I am issuing a warning here against route planning. Just as the route guides you, you get on the via ferrata with your bike and put your life in acute danger. If you want to go up on your bike, you should climb the indicated ascent (called "Abbreviation to the Swiss Gate" in Komoot) about 700m further on the Carschina Furgga. This is also not entirely without, but at least easily solved in dry conditions. I cannot from experience but I think the tour that is planned here was never ridden like this. It probably makes more sense to start the high trail (S2) from the Carschinahütte and get to the Swiss gate from the southeast. Unfortunately, I did not ride this trail , the information is therefore without guarantee.
