This segment begins in Oberradein. Follow the Zirmersteig staircase uphill through the increasingly sparce high-alpine vegetation until you come to the Weisshorn (2,317 meters above sea-level). Here you can enjoy the fabulous panoramic view before embarking on the return trip down to the Jochgrimm. There are various refreshment options as well as plenty of opportunity to admire the very diverse flora of the alpine meadows. After a short breather, the segment goes up to the Schwarzhorn (2,439 m above sea-level).
