July 2022 - second day of our Roadtrip this was our evening goal. We were welcomed by the wonderful poplar avenue which marks the southern end of the Deutsche Alleenstraße. We aimed at the only campground on the Island but fortunately left it again. A terrible place. The Islands official swimming beach offered free entrance and free shower.
The night we spent on one of the numerous parking lots, in the morning we still wanted to visit the third of the old churches. Unfortunately none of them was open during our visit, thus we missed on the islands OUV. Everything else was rather boring. Later in our trip we visited Ile. St. honorat at Cannes. Probably a comparable site, which I would rather see on the WHS list.
However, near Konstanz and the whole area is definitely another place worth visiting. Maybe at some point there might be an extension to Cultural Landscape of Lake Constanze.
