The Saxer Lücke (approx. 1,670 m above sea level) is a striking rocky notch in the Alpstein between the cantons of Appenzell Innerrhoden and St. Gallen. It is one of the best-known viewpoints in Eastern Switzerland and offers a spectacular view of the jagged rock peaks, the Rhine Valley, and the Vorarlberg Alps. The Saxer Lücke is accessible via well-maintained mountain hiking trails, including from the Staubern mountain inn or from Frümsel. The traverse between Staubern and Hohen Kasten is particularly popular. In summer, the impressive landscape and alpine flora are a draw, while in autumn, seas of fog in the Rhine Valley often create unforgettable panoramas.

I was there at the beginning of September and there was still a bit of snow. However, it was safe and the climb up the Mutschen was definitely worth it.
