Beyond Kasteel Duivenvoorde lies Den Deijl, a suburb of Wassenaar (1km/.75mile off the road to the left). This is an old-established residential district in modern Dutch style, surrounded by parks and woodland, with a Fire Service Museum (open once a week) and the popular leisure park and camping site of Duinrell.
Featuring such attractions as the "Splash", luge runs and a 3-D cinema, the Duinrell Leisure Park, a family theme park, is the largest of its kind in Europe.
The Japanese Garden in Clingendael Park in Wassenaar is best seen in the spring. The garden is a national historical monument only open at select times of the year.
