邻近 Kievietsduin, Zuid-Holland (Nederland)
This is the restricted area of Meijendel which is the best part. Day passes can be bought at the starting point for 2 euros. It is not all that easy to walk because you have to plough through sandy paths, and that can become tiresome. That's why I rated the track medium.
Note that pictures 3-6 are a little off the track, these pictures are from an previous walk.
