Park in lot, pay. We found shady spot. Nice sign at start with map, pics of wildlife. Paved trails and some sandy. Something for all skill levels. There were these cool cow like animals that are wild and graze. Watch for horns. Many birds. Trail around water. Really lovely place.
Also recommend a cemetery just down road from it. Remarkable....
Zandvoort is lokated in a nature park and surrounded by it. West is the enless sea. Nort, East and South the Kennemer Dunes with sandy hills, rivers, lakes, trees, rabbits, deers, foxes, horses and many more animals. Certainly worth to go for biking (allowed in some parts) or just walking or running for a short or a long time.
