It can be seen in Vicosoprano, Bergelia, a beautiful - still authentic - valley in the south east of Switzerland. Good that they don't show altitudes since it would put off some hikers maybe. For the locals it was clear that it is steep (Soglio is 1000m, Sett (Septimer) pass is 2300m) so all that counted was the average walking time. Soglio is the most famous place in the Bergelia since it attracted many well known people who were looking for new inspirations during a creative break. Many other places along the valley are definitely worth a stop as well, though.
