A beautiful area of (only) 34.5 hectares, characterized by reed beds, cattail ponds, and pools fringed by shrubs or with open banks... These diverse habitats offer countless bird species places to forage, nest, hibernate, or rest during their migration. No fewer than 212 species have already been observed! (Source: www.natagora.be)

Deciduous forest traversed by the Hornebeek stream. In recent decades, it has dried out considerably, especially during the summer, with the stream also drying up because the Water Group operates a drinking water extraction facility here. This permit is expiring so the stream and wet forest can slowly recover.

Through the Hornebos forest of deciduous trees and shrubs. Nature management here means "leave everything that falls or blows over." The Hornebeek stream accompanies you along the avenue. The first source immediately runs to the left of the road, while the second source emerges 200m from the right, passing under the road, where they continue together.

This fertile region was clearly a chosen area for Gallo-Roman villa builders. At a good 2.5 km apart you will find 3 tumili sites. Here the 2 Tommen van Vorsen.

'Tommen' as the Gallo-Roman tumuli are called here. Here 3 next to each other, which is rather rare. 'Tommeke, Tommeke, Tommeke' so :-)

This deciduous forest, one of the few in Droog-Haspengouw, originally belonged to the domain of Bovelingen Castle. The forest is rich in plants, including Slender Primrose and Giant Beetle Orchid. The highest point is about 130 meters above sea level. From there you have a beautiful view over the clay plateau of Haspengouw. There are sunken roads in the forest. The Peterkerebrukensloop originates in the forest, which flows into the Herk. An underground tunnel connected this stream with the castle ponds. In 1980, this forest was purchased by the Agency for Nature and Forests. Then the damp parts were overgrown with poplar and Norway spruce. In 1985 these trees were replaced by more natural vegetation, and in 2002 a further 15 hectares, bordering the forest, were planted with trees.
