Old Rhine – bathing places and shore access
Bathing places on the former Rhine arms near Diepoldsau, distinct from the flowing Alpine Rhine. No measurement station is assigned here. Place information comes from reviewed municipal and operator sources.
Old river arm, shore or natural bathing complex?
Diepoldsau municipality identifies Maz and Inseli as bathing places on the Old Rhine, with public fire pits. The Naturstrandbad is a separate bathing facility with groundwater-fed basins: its Old Rhine association describes the area, not an entry into the Alpine Rhine.
The three places have different access arrangements and facilities. Each page distinguishes confirmed information from unknown parking, supervision or seasonal details. The map locates the place; it does not indicate current swimming permission.
