Stayed here in September 2017 for a week. The site is right outside Valkenberg, no ,more than 15 mins walk to the centre. Valkenberg itself just seems to be a town of bars and cafes, great for a long weekend but not much longer. The castle really is a ruin and in my view not worth the 13 Euro admission, you can see most of it from the campsite for free! Access to the site is almost impossible when approaching from the town as the left bend is too tight. However, carry on up the hill and after 2 kms you come to a roundabout so you can then approach from the other way which is fairly straightforward. Site facilities are very dated, showers cost extra. Pitches are not big, but you do get your own hammock!! There are daily bread deliveries too.
