Be sure to leave early on weekends! It fills up quickly, and turning around (when it's full) is no fun.

The lake's location is unique; it already had 16 degrees Celsius today. A breathtaking landscape. The flora and fauna are also unique and diverse. Pure enjoyment!

An incredibly beautiful place, which we easily reached on foot from Splügen. The hut is not staffed, but can be booked for one night. Drinking water is fetched from the spring by boat... row across the upper Surettasee, enjoy the panorama, and refill your drinking water supplies at the spring... a truly adventurous experience.

The path zigzags through the forest up or down the mountain.

Mathon is located in the beautiful Viamala region and has around 50 inhabitants today. In addition to the pretty village center with its listed church, the ruins of the old St. Anthony's Church below the village are also fascinating to see.

In the small town of Wergenstein, the white church, which stands in a prime location above the valley, stands out in particular.
