This route will lead you through the Truden Horn Nature Park from the multi-faceted alpine village of Truden all the way to the charming little village of Altrei. The trail is first uphill to the Krabes-Alm, at an elevation of 1,540 meters above sea-level; this is a good place to stop for a short rest. You will then proceed along a forest trail until you come to the high-altitude bog of "Langes Moos." Then you can return to Altrei via an old cobblestone path.
