I have played on a LOT of fields worldwide (France, UK, California, Florida, Nevada...) and this one is simply the best paintball field i've ever played on.
Because the entry fee is cheap (40 us $ for 2 days, 7$ for unlimited air) , as the balls (good quality paintball similar to diablos, sold aloud 80 $ a 2000 box), and the field is totally amazing.
20 000 square meters of woods, grassy fields, speedball areas mixed up around 12 000 square meters of buildings (up to 2 stories used for playing) including bunkers, undergound corridors and laaaaaaaaaaaaaaaaarge rooms.
The field was a former WWII military training ground who hosted up to a thousand recruits... there is room for everyone !
Also, food and drinks are REAL cheap, around 3 bucks for a huge burger and 2 for a beer or coke.
Toilets are numerous and clean !
Camo are allowed on the field but military paraphernalia is strictly prohibited.
When i went there, it was for one of the semi annual big game serie : we were 700 people playing at once (divided in 2 teams) and it was just massive fun ! the size of the field and its diversity prevents any player's jam ^^
There were 60 referees on the field simultaneously, who strictly enforce the rules... Hot gun beware, they carry portable Chrony and test every suspicious marker (280 fps suggested, max 299 allowed). Rental guns are okay, but man if there is a place in the world to make your gun melt from overwork, this is here !
Security is the main priority : the site is clean of all hazards, except for the ankles (beware of a few roots and uneven floors in certain indoor areas).
Civiliian smoke grenades are allowed indoor, military grade outdoors only.
All the field messages are transmitted in english, french and german via speakers.
Many german players come play here and mostly speak english... a few speak french.
Hosting is simple :you can either plant a tent (10 $ a day) or go to one of the nearby, cosy and inexpensive hotels around (around 50 $ for a double room for one of the closest hotel)
An exciting and unbelievable fun experience, a pilgrimage for any avid big game player : it definitely worth the trip !
you need a car to go there : train station is a bit far and there is no shuttle... but maybe the managers of the field can set up one, who knows... But it is only 2 h 30 min from Paris, 30 min from Germany.
