The Free Secret Overnight Stay:
I found this cottage by accident when I met people that wanted to sleep in there but it was already taken by other visitors. They told me that this cottage is free to stay over one night. You just have to leave it exactly as you found it and keep it clean.
Hot to find the cottage:
This Cottage is located on Klewenalp. You can reach it by taking the cable car in Beckenried.
Then you need to take the Path in the direction of the Brisen and the hut Brisenhaus.
On the way, probably after around 30 minutes It's located on a small lake called Tipisee.
How does it work?
The principle is first come first served. The hut is open. So if you plan to sleep there, better get there early to make sure it's still free!
What's special about it?
This little cottage is listed nowhere on the internet, you just have to know about it.
