In the location's words:

The Silbersee in Langenhagen is a large quarry pond covering around 6.8 hectares, embedded in park-like nature with extensive sandy beaches, sunbathing lawns and historic trees: perfect for swimming, sunbathing or beach volleyball. With a depth of up to 15 m, barbecue areas, mini golf, a kiosk with beer garden and weekend supervision by the DLRG, it offers a wide range of leisure activities. Particularly popular: a separate, fenced-in dog beach and designated areas for pets, so that visitors with dogs can enjoy relaxing summer days here
