River dunes along the Maas
De Maasduinen National Park lies on a long sandy ridge between the Maas and the German border, mostly in the municipality of Bergen. The park is more than 20 kilometres long, two to three kilometres wide on average and covers more than 4,500 hectares. This is the longest belt of river dunes in the Netherlands.
In the last Ice Age, a strong westerly wind blew sand from the Maas valley to the east bank. That is how the parabolic dunes formed: horseshoe-shaped dunes 15 to 25 metres high. Later the sand began to drift again and was fixed with conifer forest. Between the woods and the heath there are now fens, open drift sand and, near Well, the Reindersmeer, a former sand and gravel pit.

The De Hamert estate
In the south, near Wellerlooi, lies the De Hamert estate of Het Limburgs Landschap: more than 1,000 hectares of woodland, heath and fens. This is where most of the park’s parabolic dunes are. On one of the crests lies the Vorstengraf, 25 metres wide and almost 3 metres high, one of the largest burial mounds in the Netherlands. From the mound you look out over the Pikmeeuwenwater, a fen with remnants of raised bog.
In spring and autumn, migrating cranes rest on fens such as the Heerenven; that is why the crane is in the park’s logo. Along the Twistedenerweg runs the Geldernsch-Nierskanaal, dug more than 200 years ago and, because of the difference in height with Germany, now a fast stream with steep banks. Kempen heath sheep and goats keep the heath open.

The Bergerbos and Bleijenbeek
In the north, near Afferden, lies the Bergerbos of Staatsbosbeheer: 561 hectares of river dunes, woodland and heath. From the lookout tower on the heath, you see the dunes roll away. In the woods lie nutrient-poor fens such as the Quin, the Zevenboomsven and the Esven, and at dusk the rare nightjar hunts here.
South of the Bergerbos stands the ruin of Bleijenbeek Castle. Building began shortly before 1300; in 1945 a bombardment destroyed the castle. Today bats fly here at dusk and beavers live in the moat. The ruin is open by appointment; at Paviljoen Bleijenbeek, one of the park’s visitor points, you will find information about the area.

Tip from reception
Drive to Jachthut Op den Hamer in Wellerlooi, about twenty minutes, and park in car park P1. Take the blue route of 4 kilometres: it crosses the heath past the Vorstengraf and the war memorial. Afterwards, have a coffee in the Jachthut itself.

Good to know
Four starting pointsThe visitor centre near Well, Jachthut Op den Hamer in Wellerlooi, and De Zevenboom and Paviljoen Bleijenbeek in Afferden. The park is long: choose the starting point nearest the part you want to see.
Waymarked routes17 walking routes with coloured posts, so you do not need a map. On De Hamert they range from 1 to 5 kilometres. Wear sturdy shoes: the dunes can be quite a climb.
With your dogDogs are welcome, usually on a lead. They may run free in two areas of more than 10 hectares: in the Bergerbos near Afferden and by the Eendenmeer in Nieuw-Bergen.
Grazers on the heathSheep, goats and Galloway cattle keep the heath open. They are still wild animals: keep at least 25 metres away from the herd.
