Arthur-Hartdegen Trail

From Rein (1,602 m) follow the road to Knuttental valley, and from there follow the trail on the right (marker 8a) across the wide bridge over Knuttenbach / Valle dei Dossi rivulet to a well situated farmhouse. The trail leads through the woods to Untere Kofleralm (2,034 m), and from there through a beautiful cembra pine forest to Obere Kofleralm (2,192 m). The trail (still no. 8a) now leads slightly uphill across a slope to Ursprungalm (2,393 m), where there is a magnificent view of the Rieserferner mountain glaciers.
You then proceed to Kasseler Hütte refuge (marker 8) along part of a trail called Arthur Hartdegenweg, which allows for spectacular mountain hikes above Reintal / Valle di Riva valley. After crossing Ursprungbach rivulet, bypass a mountainside until you see the majestic glaciers of the Rieserferner mountains. The trail is well maintained, but here is one section where you need to exercise caution. After crossing the final moraine of Hochgall, you will reach Kasseler Hütte refuge (2,275 m). From there, you make the gradual descent to Reintal valley on trail 1, which leads past a series of pastures high above Bachertal valley / Valle di Rio.
