Kleiputten van Wenduine

Kleiputten van Wenduine is a compact but bird-rich nature reserve on the edge of Wenduine, a coastal district of the municipality of De Haan in West Flanders, Belgium. Covering roughly 11 hectares, the site borders the expansive Uitkerkse Polder and sits between the center of Wenduine and the neighboring district of Harendijke. The small Bommelzwin watercourse runs through the area, feeding the ponds and wetlands that define the reserve.

Where does the name "clay pits" come from?

The Dutch name "kleiputten" literally means "clay pits," and it points directly to the site's origin. The depressions in the landscape were formed by historical clay extraction, once used for local construction and brickmaking. After extraction stopped, the pits gradually filled with water, forming a network of small ponds that were slowly colonized by plants and animals typical of wetland habitats.

A turning point in the reserve's history came in 2010, when the Flemish government purchased the land as compensation for habitat loss caused by the expansion of the port of Zeebrugge. The site was then converted into a protected nature area, managed since by Natuurpunt, Flanders' largest nature conservation organization.

Why visit?

Kleiputten van Wenduine is above all a destination for birdwatchers. The combination of open water, reed beds, and wet meadows draws both breeding species and migratory birds that stop here during their seasonal journeys. To support visitors, the reserve provides dedicated birdwatching infrastructure — a viewing wall (kijkwand) and an observation tower, both designed to let visitors watch birds closely without disturbing them.

Its close connection to the Uitkerkse Polder means the reserve functions as part of a larger ecological corridor important for waders, ducks, and other wetland bird species. Natuurpunt regularly organizes guided walks and educational outings here, including cycling trips through the surrounding polder landscape, where guides help visitors identify species and explain the ecological value of these wetland habitats.

Planning a visit

The reserve lies within walking or short cycling distance of central Wenduine, a popular seaside resort known for its wide beach and for being a stop on the Kusttram, the coastal tram line that connects it easily to neighboring resorts such as De Haan and Blankenberge. The best times to visit are during spring and autumn migration, when the variety of species passing through peaks, though the reserve also attracts wintering birds drawn to the surrounding waters in the colder months.

Binoculars are recommended, since birds are typically observed from a distance, at designated viewing points along the reserve's edges. The terrain is flat and accessible to walkers of most ages, making it a good choice for a quiet, contemplative outing away from the busier stretches of the Belgian coast.
