A new site to us in 2016 is Camping Grimbergen situated just off the Ring around Brussels.
This site is excellent for an overnighter or to visit the lovely city of Brussels which is around 12 km from the campsite. It has, I think 49 pitches and is very secure. Very friendly and helpful owner. Toilet/Shower blocks excellent and spotlessly clean only thing missing were Toilet roll holders and toilet paper. Free WiFi at the Reception and we could just get it on Pitch No, 3.
This is not an ACSI Camping Card but ACSI Inspected Price inc. Electricity was €24 per night. Water nearby, All very tidy and short grass. Website:- here
No Restaurant but an excellent Brasserie next door named Lammekeshoeve excellent food though a bit pricey.
