Starting in Trodena/Truden we take the European long distance path E5. We walk through a wonderful mixed coniferous forest, partly on a forestry trail, partly on an old path and we get to the col “Ziss-Sattel”. The trail continues to the alpine cabin “Hornalm” on 1.710m which is surrounded by large meadows and high alpine plants: gentian, milkworts, sulfuric anemones and bearded bellflowers. The panoramic view from the Hornalm is surely worth the tiring climb: You have a wonderful view over the mountain chain “Lagoraikette”, the Palagruppe, the two mountains Schwarzhorn and Weißhorn, the Zanggenberg, the Latemar, the Rosengarten group, the Schlern and the Alps of the Stubaital and Ötztal. After a side-trip to the “Schwarzensee”, a black lake and biotope, we walk around the top of the Trudner Horn and take the path E5 back to Trodena.
