There’s quite a few!
Best recommendation would be Skirmish near Aberford (A64/A1 junction) – paintballuk.com. Good pitches in the woods, lots of variety last time I played and a good set of marshals.
Harrogate Paintball Centre – paintballyorkshire.co.uk – looks alright. Not been to play but looked around and seems like a decent set of pitches to keep you entertained
Not tried the Yorkshire Paintball Centre – ypc.co.uk – but might be worth a look for any deals
Bottom of the list would be Elite at Hemsworth. Was there last week, 5 open pitches, all man-made obstacles etc. not much in the way of cover and a but boring and slow, to be honest. Felt slightly sorry for the marshals!
Hope that helps!
