Beerschoten to Maarn via Groot Heidestein, Landgoed Bornia and Koeheuvels

Starting from the edge of Beerschoten Estate, just outside the village of De Bilt, this 15 km (about 9.3 miles) route offers a gentle, nearly flat walk through some of the most scenic and ecologically rich landscapes of the Utrechtse Heuvelrug region. The trailhead is easily accessible by public transport: take a train to Bilthoven station, then a short bus ride or a 2 km (1.2 mile) walk brings you to the entrance of Beerschoten. For those arriving by car, parking is available at the Beerschoten estate visitor center, located at De Holle Bilt 6, 3732 HM De Bilt.

Beerschoten and Groot Heidestein: Woodland and Heath

The hike begins in the stately Beerschoten estate, known for its grand avenues, ancient oaks, and open meadows grazed by Highland cattle. Early on, you’ll pass ornamental ponds and remnants of 19th-century landscaping, a reminder of the area’s history as a country retreat for Utrecht’s elite. After about 2 km (1.2 miles), the trail transitions into Groot Heidestein, a nature reserve famed for its rolling heathlands and scattered juniper bushes. In late summer, the heath erupts in purple bloom, attracting butterflies and bees. Watch for grazing sheep, which help maintain the open landscape, and keep an eye out for buzzards and woodpeckers in the bordering pine woods.

Landgoed Bornia: Shifting Sands and Pine Forests

At roughly the 6 km (3.7 mile) mark, you enter Landgoed Bornia, a vast estate characterized by sandy soils and undulating pine forests. This area is a haven for wildlife—roe deer, foxes, and even badgers are occasionally spotted. The sandy paths can be soft underfoot, especially after dry weather, so sturdy footwear is recommended. The Bornia estate is also notable for its shifting sand dunes, a rare habitat in the Netherlands, formed by centuries of grazing and wind erosion. Pause at one of the wooden benches to take in the silence and the scent of pine needles.

Koeheuvels: Open Heath and Panoramic Views

The final section, starting around 11 km (6.8 miles), leads you through the Koeheuvels, a striking expanse of open heathland dotted with solitary birch trees. This area is particularly valued for its tranquility and wide, open skies—ideal for birdwatching, especially during spring and autumn migrations. The Koeheuvels are also home to several Bronze Age burial mounds, subtle grassy humps that hint at the region’s ancient human history.
