Dwingelderveld is the largest continuous heathland in the Netherlands, a national park of about 3,700 hectares lying just north of Ruinen. In late summer — roughly August to September — the heather blooms purple across the whole expanse, one of the most dramatic seasonal landscapes in the country. Outside the bloom, the park has a quiet, open beauty: sandy paths through pine and birch forest, pools and wetlands, and extensive views across flat heath where only the sound of wind and birds interrupts.
Cycling is the best way to explore the park — the flat terrain makes it accessible for all abilities and a network of well-signed paths covers the whole area. The visitor centre near the entrance has maps, exhibits on the park's ecology, and information on the best routes. Sheep herding is practised here to maintain the heathland, and the traditional Drenthe sheep (Drentse Heideschaap) can often be seen grazing. The Dwingeloo Radio Observatory, visible on the park's edge, was where hydrogen radio emissions from our galaxy were first detected in 1951.
