try this, 4X4 Off Roading Doncaster Overview
dunno wat ur price range is though. and dont know if ya can take ur own landy. probably not. but sounds like they cater for all levels of challenge
Frickley 4x4 centre is good - been there a couple of times and know one of the chaps that run it through work. Some nasty rocky stuff that will rip your exhaust off and bend your steering geometry should be avoided.
Theres Kirton lindsey quarry every last sunday of the month, Google "KORK". Parkwood 4X4 experience can't be that far either, Google "Parkwood 4X4", An theres Cowm that's somewhere in that neck of the woods as well.
