When the weather is nice, the food carts are open with tables. Swimming in the Linth: A matter of course for locals, for others it can be a challenge to get into or jump into the cold, rushing Linth. With little water (July/August), the Linth can also be waded through.

Beautiful, but also very busy and well-trodden path along the northern shore of the Obersee.

A very beautiful lakeside promenade, easily accessible by bike. The baroque church next door is also worth a visit!
