We've visited over 10 belgian recball fields now. The best are posted here
I've updated it because I think that safety is a very important issue. When you're new you don't even notice something is unsafe.

You play on an old Belgian fort wich was used to defend Antwerp as part of a large belt of forts in the great wars. With some great features as knee high grass in wich you can crawl. It still breathes ww2 in my opinion and is a great place for strategic players. The staging area/safety zone(where you wait when you're out) has a great vantage point to watch the ongoing game. There is no netting around this part and I find this very unsafe.

I think this must be the best & biggest field in belgium. The web-site is not a good representation of the field. 5 different fields and some nice lay-outs. The only downside is the rather long drive, because its it the southern tip of Belgium.
http://www.forest-paintball.be/ I recommend this one for peeps with their own equipment. Nice big place with some nice vegitation (some more obstacles would be nice). Best prices I've seen untill now. I dont like the fact that another field is real close and there is no real seperation between the 2 fields. There is no netting around the terrain whatsoever. When you're out, you walk just beside the gaming terrains with no netting so removing your goggles isn't safe.
This is not meant to be a flamin' post. I will NOT put up fields I dislike here. When you got a field you wanna visit you can drop me a pm and I'll give you some advice if it's one I visited before.
Little Tip: Iff you need an invoice be sure to get some type of payment proof when you step off the field. Some fields dont sent invoices even when asked for several times. This is an issue i experienced 2 times now so watch out for this.
