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?

Drei Weieren (St. Gallen)

Highlight • Lake

The Dreiweihern are actually worth a trip. However, the two largest ponds have been drained (maintenance work, probably a few more weeks). Worthwhile, as the pond floor is visible for once.

Description: A relatively easy trail with a few sections that require caution, both during the ascent and the descent. It’s a nice route for those who enjoy moderate hiking without technical difficulties, but attention is needed in some steeper or uneven parts. Ideal for a short adventure close to nature. Why I recommend it: This route is perfect for beginners or casual hikers who want a bit of challenge without being overwhelmed. The views are rewarding, and the trail offers a nice balance between ease and small moments of focus.

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/

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.

The funny thing about it: dogs are allowed to swim in the Bubenweiher lake, but not humans :)! https://www.teddy-b.ch/ausflugsziele/drei-weieren-st-gallen-wasserwelten/
