Hobokense Polder

Hobokense Polder is the largest nature area within the city of Antwerp — 170 hectares of green space squeezed between the Scheldt river, the Hoboken district and surrounding industry. For city residents it functions as a wild enclave where meadows, scrubland and wetlands sit directly next to a heavily industrialized and port-driven landscape, making it an unusual contrast within a large metropolitan area.

What is the history behind this place?

Until 1940, Hobokense Polder was still a rich, extensive polder landscape covering more than 220 hectares, typical of the low-lying river terrain found throughout Flanders. During the 1950s and 1960s, part of the land was raised using sand excavated during construction of the former E3 motorway (today's E17). The plan behind this earthworks was an ambitious urban development called "Polderstad" — a new residential district with homes, schools and shops, complemented by a zone for small and medium-sized businesses. The project was ultimately never built, and the abandoned land was left to regenerate on its own, gradually turning into the naturally evolved landscape visitors see today. The area gained official nature area status in 1995, followed by recognition as a nature reserve in 1998.

What can visitors see there?

Decades of unmanaged natural succession have turned Hobokense Polder into a surprisingly biodiverse site. More than 500 plant species and around 360 fungi species grow here, including orchids that flower in spring. The reserve draws migratory birds resting during long journeys, as well as breeding species such as water rails, golden orioles and bluethroats. Countless insects and other small animals also live in the polder, among them roughly 300 species of moth. Large grazing animals, including Galloway cattle, are used to maintain the open character of the meadows by naturally keeping shrub growth in check.

How can you explore Hobokense Polder?

The reserve is managed by Natuurpunt, a Flemish nature conservation organization that maintains a network of walking trails open year-round and free of charge. Visitors can explore independently or join guided walks led by nature guides. Several observation hides and platforms are placed along the routes, allowing visitors to watch waterfowl and wading birds without disturbing them. The reserve is popular both with locals looking for a quiet walk close to home and with birdwatchers and nature enthusiasts visiting Antwerp.

Frequently asked questions

Is entry to Hobokense Polder free? Yes, the area is open to the public and free to visit throughout the year.

How large is the reserve? It currently spans about 170 hectares, though historically the polder was larger, exceeding 220 hectares before the mid-20th century land alterations.

Why is this site unusual for an urban setting? Because despite being surrounded by industry and built-up areas, it developed over decades into a fully natural ecosystem with rich flora and fauna, largely as a result of an abandoned urban development plan from the mid-20th century.

Who manages the site? Natuurpunt, a nature conservation organization active across Flanders, which also carries out grazing management with livestock as a natural way of shaping the landscape.
