Good spot for taking a break or escaping a sudden storm! There's some places to sit, as well as an overhanging roof where you can hide from the rain :)

There's so many great views around the lake, and this is one of them! On a clear day, you can see very far in the distance. But even with less-than-perfect weather, there's still a lot of natural beauty to enjoy.

Colloquially, this bridge is called "Ganggelibrugg" because it sways slightly (ganggelet) due to its light construction.
