On the Herzogenhorn is an extensive network of cross country skiing training trails. The routes starting at the National Training Centre (about 15-20 km, depending on snow conditions) lead in tight loops across the hilly plateau between the Herzogenhorn, Grafenmatt and Silberberg and are the highest loipen in the Black Forest (approx ). They are therefore often used for training. The trails, which are all challenging, are accessible from the Feldberg Pass over the Grafenmatt lift or by crossing the alpine slopes of Grafenmatt in about 20 minutes on a groomed forest path.
