Seealpsee

Highlight • Lake

Beautiful mountain lake in the middle of the Alpstein, with a panorama that couldn't have been created better on the computer. Free-roaming cows, bright green sparkling water, cheese dairy, alphorn players... what more could you want?

Fählensee

Highlight • Lake

The Fählensee is the third largest mountain lake in the canton of Appenzell and is located in a very narrow valley between the Bollenwees mountain inn and the Zwingli Pass, embedded between the Hundsteingrat and Roslen-Saxer-First. Just beautiful. Highly recommended!

Lake Sämtiser

Highlight • Lake

Sämtisersee at 1200 meters
As with Fählensee, there is no outflow to be seen here. The water from both lakes flows underground and reappears in the Rhine Valley. Outflow or not, enjoy a refreshing swim!
The water level fluctuates greatly, which is why Sämtisersee almost dries out in very hot summers.

Sämtisersee, Alpstein region The picturesque Sämtisersee is located above Brülisau in the municipality of Rüte in the canton of Appenzell Innerrhoden. The Appenzell mountain lake is located at the foot of the Hoher Kasten in the Alpstein region at an altitude of around 1200 meters above sea level. The Seealpsee and the Fälensee, the other two larger lakes in the Alpstein, are each about three kilometers (as the crow flies) to the southwest. The Sämtisersee is fed by various streams, especially the Sämtiserbach. Text / Source: schweizersee.ch https://www.schweizersee.ch/saemtisersee/

Very beautiful mountain lake at 1447 m above sea level, which, like the Sämtiser and Seealpsee, is part of the Alpstein. Ideal for cooling off after a hike. When there is no wind, the mountains are beautifully reflected in the water.
