Meersburg is a beautiful, historic city consisting of the Lower Town and the Upper Town. The lower town is located on the water, while the upper town is located on a hill. Great viewpoints are the New Castle and the castle.
Worth to visit are ice cream parlor near the city gate and in the middle of the pedestrian area the snack bar with good value for money especially the castle. The new castle I found a bit disappointing, since only a few rooms to visit.
