OK, this one might be totally obvious but we thought it was quite fun. We rented a paddleboat, then another time a motorboat, from the place right next to the ferry dock at Burkliplatz. Our son loved being on the water and helping to “drive” the boats. It’s a relaxing way to spend an hour.
There were no child-size life jackets, maybe bring your own.
That tiny boat out there is us.
