The lake on both sides, the city and the castle make for a wonderful panorama. You also forget the very busy Seedammstrasse behind you.

A busy but beautiful route across the dam, partly with a wide cycle path. Unfortunately, the section from Hurden to Pfäffikon on the gravel path is now closed to cyclists (until the first accident happens on the main road).
