De Meinweg
Three river terraces stacked like stairs on the German border — the adder capital of the Netherlands, wild boar in the oak woods, and a dormant railway that keeps lawyers busier than trains.
De Meinweg is the Netherlands practising relief. East of Roermond, jammed into a bulge of Limburg surrounded on three sides by Germany, the old Maas and the little river Rur cut the land into three broad terraces that step up fifty metres in a couple of kilometres — a terrassenlandschap unique in the country, with actual slopes, actual ravines where brooks like the Boschbeek saw down through the gravels, and viewpoints that look out over Germany rather than polder. The name is medieval: the Meinweg was a commons — "common way" — shared by fourteen surrounding villages under written rules from 1338, and the park's boundaries still roughly trace that shared waste of heath and oak.
Poor gravel soils kept it wild enough to become, quietly, the country's best reptile ground. The south-facing terrace scarps and heathy plateaus hold the densest adder population in the Netherlands, along with slow-worms and sand lizards, and spring mornings on the Vlodropperveld are a connoisseur's exercise in walking slowly and watching the path edges. The bog pools of the middle terrace — the Rolvennen, and the Elfenmeertje with its water lilies — bring dragonflies in southern numbers, while the oak-and-pine woods carry wild boar as a fixture: for most of the twentieth century the Meinweg and the Veluwe were the only two places in the country that had them at all, the Meinweg's sustained by traffic across the German line, which animals have never respected. In April 2020 a fire took roughly two hundred hectares of the dry heath in a single corona-spring afternoon — the scar on the middle terrace is regreening, and the park now reads it as both wound and warning.
Across all three terraces runs the park's strangest monument: the IJzeren Rijn, the Iron Rhine, the 1879 freight railway from Antwerp to the Ruhr, dead straight through the woods. No regular train has used it since 1991, but Belgium's treaty right of way survives, and every few years a reactivation study sends the park, three governments and an international arbitration ruling (2005, Permanent Court of Arbitration — the park largely won) back into the ring. Meanwhile the empty ballast bed grows broom and sand lizards, and walkers cross it like a Roman road.
What's worth knowing before you go
Enter from Herkenbosch: the road in past the Meinweg visitor farm at the Boshotel is the only car access deep into the park, and the marked loops radiate from there — the Rolvennen circuit is the essential one. Roermond is the rail approach, with a bus to Herkenbosch and honest cycling distance beyond. Come in April–May for adders basking after cold nights (warm morning after a chilly one; stay on the path and they'll ignore you), August for heather, October for boar sign everywhere and the terraces in colour. And walk into Germany on purpose — the trails stitch straight into the Naturpark Schwalm-Nette network, and the border stones in the woods are the only formality anyone observes.
