The Stadtwaldsee in Bremen – usually simply called "Unisee" – lies directly next to the university in Horn-Lehe. It was created in the 1970s as a result of construction and sand extraction work following the building of the motorway. The lake, which is approximately 15 meters deep and covers 29 hectares, is fed primarily by groundwater. The lake is an easily accessible local recreation area for the residents of Bremen. On the bathing side, there are sunbathing lawns and beach areas.

Emmasee in Bremen's Bürgerpark is an easily accessible destination if you're simply looking for a bit of peace and quiet. Passing clouds are reflected in the lake, and a light breeze rustles the leaves. The lake is named after Countess Emma von Lesum. Right on the shore is the café "emma am see," built in 1964 according to designs by architects Hans Budde and Carsten Schröck. Opposite the café is a rowboat rental if you'd prefer to explore the lake from the water.
