Freshwater quarry lake with forest access and two basins.
Freshwater quarry lake with forest access and two basins.
Flughafen See is a traffic-free quarry lake north of the former airport, reached by an eastern-side forest walk and organized around a larger main basin and a smaller forebasin. It suits divers, freedivers, and swimmers who want sheltered freshwater conditions and a quiet urban escape rather than open-water exposure. The lake works best as a low-drama training or practice site when water quality and clarity are acceptable.
