The ponds are known for their history of 'poldering' or emptying the ponds during autumn to harvest fish and maintain the ecosystem.
The area is home to the largest concentration of breeding populations of the protected tree frog in Flanders.
The 'Cycling through the Water' path allows cyclists and pedestrians to travel at water level, with the surface rising on both sides of the path.
The entire region consists of over 1,000 ponds covering more than 700 hectares of water surface.
The ponds were originally created by the Cistercian monks of the nearby Herkenrode Abbey in the 13th century.
The specific soil composition in this part of Limburg allowed for the construction of water-retaining ponds without modern artificial liners.
De Wijers, often called 'Land of 1001 Ponds', is a unique nature reserve and living museum situated between Hasselt and Zonhoven in Belgium. It encompasses a vast landscape of interconnected fish ponds that have been cultivated since the Middle Ages. The area serves as a habitat for the rare bittern and the tree frog, which are focal points of the local conservation efforts. Visitors explore the site through a network of trails, including the iconic 'Cycling through the Water' path that bisects a large pond. The visitor center at De Wijer provides context on the historical development of the region's aquaculture. Educational displays demonstrate how monks historically managed these ponds for carp farming. It is a key node in the larger Limburg pond region, combining biodiversity protection with heritage preservation.

Wear waterproof footwear if visiting after rainfall, as trail sections near the water can become muddy.
Bring binoculars, as the reserve is a premier location for birdwatching throughout the year.
Check the local meteorological forecast, as the open pond landscape offers minimal shelter from wind.
Do not attempt to feed the waterfowl, as this disrupts the delicate ecological balance of the pond habitats.
The outdoor trails are accessible year-round, but specific visitor center exhibitions may have seasonal closures on weekdays in winter.
Stay on marked trails to protect sensitive flora and fauna; no dogs off-leash.
