Plas Walenhoek and Pottum Loop

Starting from the tranquil surroundings near Walenhoek Nature Reserve, this 7 km (about 4.3 miles) loop offers a flat, easy stroll with virtually no elevation gain, making it accessible for hikers of all abilities. The trailhead is conveniently located near the entrance to Walenhoek, a well-known nature area in Niel, Belgium, just south of Antwerp. For those arriving by public transport, Niel railway station is the closest stop, less than 2 km (about 1.2 miles) from the reserve, with regular train connections from Antwerp and Mechelen. If driving, parking is available at the Walenhoek entrance on Boomsesteenweg.

Navigating the Loop

The route is well-marked and can be easily followed using HiiKER, which provides up-to-date trail maps and navigation tools. The path meanders through a mosaic of ponds, reed beds, and willow groves, remnants of the region’s clay extraction history. Expect wide, well-maintained gravel and dirt tracks, suitable for families, casual walkers, and those with limited mobility.

Nature and Wildlife

Walenhoek is a haven for birdwatchers, especially in spring and autumn when migratory birds flock to the wetlands. Look for herons, grebes, and the occasional kingfisher darting across the water. The ponds are fringed with wildflowers in summer, attracting butterflies and dragonflies. The loop also passes through Pottum, a quieter section where you might spot roe deer or foxes in the early morning.

Historical Significance

The landscape tells the story of centuries-old clay pits, once vital to the local brick-making industry. Many of the ponds you’ll pass are former excavation sites, now reclaimed by nature. Informational signs along the route explain the transformation from industrial use to protected wetland, highlighting the area’s importance for biodiversity and local heritage.

Trail Highlights and Practical Tips

At around 2 km (1.2 miles), you’ll reach a wooden observation platform overlooking one of the largest ponds—an excellent spot for a rest and some birdwatching. Benches are scattered throughout the route, and picnic tables can be found near the halfway point. The terrain remains flat throughout, with no significant climbs or descents.

There are no cafés or shops directly on the trail, so bring water and snacks. Restrooms are available at the Walenhoek entrance. Dogs are welcome but must be kept on a leash to protect wildlife. The loop is open year-round, though waterproof footwear is recommended after heavy rain, as some sections can become muddy.
