The Hobokense Polder is one of the most beautiful green spots in Antwerp. In a Scheldt riverbend near the city you will find a varied landscape - from polder over marsh to forest. Due to the large variation in vegetation, there is also a large variation in the avifauna present. Some nice birds you can see are Water Rail, Common Cuckoo, Little Grebe, Northern Shoveler and European Honey-buzzard.
Plenty of parking at Hoboken polder train station; from there it is easy to make 2 walks (6 & 9 km).
