The ferrata Cir is a hort one which doesn't mean it's easy. It requires a bit of experience. You don't need a whole day on it, it's enough if you plan an afternoon to do it. You will be astonished in how short time you can reach a peak and be on you own far from the daily confusion and other people. From the peak you will have a great view on the Vallunga.
Through the valley of Gardena until the Gardena Pass or from Selva directly with the cable car Dantercepies
