Hoher Kasten Summit

The striking mountain peak has been accessible from the Appenzell side with a cable car since 1964. It takes eight minutes to overcome the 869 m difference in altitude from Brülisau.
In May 2008, a revolving restaurant was opened on the mountaintop.

Very nice view and easy to reach thanks to the cable car.
Accordingly, you are rarely alone here.

Hoher Kasten revolving restaurant
Just sit down and enjoy "rondom". In the only revolving restaurant in Eastern Switzerland on the Hoher Kasten, guests experience a limitless, changing 360° view. While the view stretches from the impressive backdrop of the Alpstein, across the lovely Appenzellerland to the expanse of Lake Constance, we spoil you with seasonal and regional specialties.
The revolving restaurant is open daily from April to February during the cable car's operating hours and is easily accessible by lift for guests with limited mobility.
