The estate grounds contain the ruins of the 13th-century Ter Horst castle.
The Eikenhorst mansion, located on the estate, is a notable example of modern-era royal residential architecture.
The area is home to a diverse population of woodland birds, including various woodpecker species and owls.
De Horsten was once part of a larger network of aristocratic hunting grounds in the Wassenaar region.
The estate features a distinct 'Tea Pavilion' (Theepaviljoen) that functions as a focal point for visitors.
The park's drainage system and water features were historically modified to maintain the formal aesthetic of the royal garden influence.
De Horsten is a historic 400-hectare estate in Wassenaar, formerly the private residence of the Dutch Royal Family. The landscape is characterized by a mix of English-style gardens, mature woodland, and ancient carriage paths. It serves as a significant ecological corridor connecting the dunes to the inner land. Visitors can explore the grounds, which include the Raaphorst, Ter Horst, and Eikenhorst estates. The latter famously served as the residence for King Willem-Alexander and Queen Máxima before their move to Huis ten Bosch. The site is managed by the De Horsten Foundation, emphasizing conservation and public access to its varied forest and meadow habitats. It remains a quiet refuge for native Dutch wildlife and bird populations.
The scenic bridge near the Tea Pavilion offers a view of the water and the surrounding forest canopy.
Wear waterproof footwear as the woodland trails can become muddy after rainfall.
Keep a safe distance from grazing livestock if you encounter them in the meadow sections.
Bring binoculars to spot the diverse birdlife present throughout the wooded canopy.
Do not attempt to access restricted residential areas or private royal buildings not marked for public footpaths.
The estate grounds are accessible daily, but specific paths may be restricted during periods of heavy maintenance or wildlife breeding seasons.
Dogs must be kept on a leash at all times; stay strictly on marked paths to protect ground-nesting birds.
