There is a camping site located near a wash house. It is separated from the campsite by tall hedges. You can access it through De Isselhoeve or Children's Pretparadijs. It is situated in front of the wash house on the left side.
I asked the staff and they directed me to the 4 parking spaces located 300 meters away. The fee is 10€ and can be paid at the machine. It seemed alright, but there was a large crowd on the road right next to it. I decided to keep driving because I felt too exposed.
Book recommendations can be helpful as they offer unique perspectives and opinions not found in books. It's always interesting to see what others think and form your own judgment.
