The lake can be bypassed with a mountain bike. Two gates can only be bypassed by stopping and pushing. :-(

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 restaurant is the entrance to the Roffla Gorge. The entrance fee of CHF 4 is well worth it. You can also enjoy a fine meal at the restaurant after the tour. The wooden tables in the garden restaurant come from the restaurant's own sawmill, and the awning in front of the restaurant comes from the restaurant's own spinning mill.

Beautiful lake. In May everything was still frozen over and I felt like I was on another planet in the sleet.
