We keep talking about classic style or skating, and you're just thinking, "Huh?" We don't want to leave those questions unanswered.
In classic style, arms and legs are moved diagonally to each other on a groomed trail. This technique is perfect for beginners and is also easier to learn. In skating, you move similarly to inline skating and are also faster.
The Hinterstoder Ski School is located right next to the Explorer Hotel Hinterstoder. Here you can book a cross-country skiing course and get an introduction to cross-country skiing technique.
P.S. You can also try biathlon at the Innerrosenau Cross-Country Skiing and Biathlon Center in Rosenau. (35 minutes by car)
