Please note that the water sports area at Allersee may occasionally be closed due to events. However, the swimming area remains accessible to all visitors.

As soon as a red flag is hoisted at the DLRG tower or the water rescue station, the following applies:

- No boats, SUPs, pedal boats, or other watercraft are allowed on the lake.

- Swimming is only permitted within the marked swimming areas.

- Swimming outside the swimming areas is prohibited.

The flag is raised during DLRG operating hours. Outside these hours, clubs and residents are responsible for marking the areas themselves.
