Teufelstisch (Wallhausen) – exemption only
Diving is prohibited without an individual exemption. The Teufelstisch is a rock needle standing in front of the steep wall at Wallhausen on the Überlinger See, with sea mark 22 on its top. The Konstanz district office has banned diving here since 1979 (amended 1994), within 300 m to the north and north-west and 500 m to the east and south-east of the sea mark. Experienced divers can apply for a paid exemption valid for two years.
