Unterbacher See (Strandbad Nord and Strandbad Süd)

Unterbacher See is the main bathing lake of Düsseldorf, a former gravel and peat pit flooded into a recreation area in the suburb of Unterbach, about 10 km east of the city centre in North Rhine-Westphalia, Germany. Instead of a sea or river beach, the shore consists of sandy lawns and groomed sand strips around two supervised lido areas, the Strandbad Nord and the Strandbad Süd. The water is fresh, generally clear enough for swimming in summer, and calm because the lake is sheltered and small compared with open water, so there is no surf and little current. The shape is that of an enclosed lake with a largely open shoreline, which makes it easy to find a place on the grass or sand within sight of the water. The atmosphere is mostly relaxed and family-oriented, with children paddling in the shallows, groups picnicking on the lawns and sailors, windsurfers and stand-up paddlers using the lake beyond the swimming zones. One of the lido areas has a designated naturist section, so visitors who prefer clothing should check the layout at the gate. Amenities include toilets and changing rooms, kiosks and restaurants, and supervised swimming zones during the bathing season, with lifeguard hours following the lido opening times, which should be confirmed locally. A sailing school, surf school and SUP launch operate on the lake. Entry to the lidos is by day ticket sold at the gate; an older local report put the adult price near EUR 4.80, but the current price should be confirmed before the visit. Access is straightforward: Rheinbahn tram or bus lines run from Düsseldorf Hauptbahnhof towards Unterbach and Unterbacher See in roughly 35 to 45 minutes, and the Deutschlandticket is valid on them. Car parking is available at the lake, although spaces fill early on hot weekends. A path around the lake also suits walkers and cyclists, so a visit can combine a swim with a longer loop. Because it is the most complete bathing facility in the city, it is the usual choice for visitors who want a proper day at the water rather than a view of the Rhine.
