The Hallerey nature reserve in Dortmund, with a size of around 72.1 hectares, offers an idyllic natural landscape for nature lovers and those seeking relaxation. The area, which has been protected since 1977, is characterized by its diverse flora and fauna. The Hallerey offers an impressive natural spectacle, especially in spring and summer when the plants are in full bloom. The plants that grow here include, for example, the light purple waterwort, the yellow groundsel and the delicate pink flowers of wild roses. The Hallerey is also an important habitat for a rich world of insects and birds. Over 174 species of large butterflies, including peacock butterflies, small tortoiseshells and brimstone butterflies, find a habitat here. The area is also home to over 240 species of birds, including rare species such as the little grebe and grebe, various species of geese, ducks and the reed bunting. The second largest colony of black-headed gulls in North Rhine-Westphalia, located in Hallerey, is remarkable. Visitors can also explore the nature reserve by bike. A paved path runs along the lake and offers a pleasant route through the nature reserve. The Hallerey is therefore a perfect excursion destination for anyone who longs for a break in the countryside, be it on foot, by bike or to observe the diverse flora and fauna. The Hallerey nature reserve is easily accessible and is located in the immediate vicinity of the Wischlingen Revierpark. Public transport, such as bus lines 447 and 461, tram lines 403 and 404, and S-Bahn line 2, stop at the nature reserve, and there are also park-and-ride parking spaces at the Marten Süd stop
