good question that mr ed.
i got lost first time i went there but it easy once you know....
enter the camp and drive up the road for about 200 yds and take the first left. (its kind of a "y" junction.
follow this road for a few hundred yards (over the speed bumps) and as you come out into the open past the caravan site the road splits.
take the left hand direction and the car park is in front of you.
if you dont see a couple of hundred misfits wandering around with slug guns then youve not followed these directions!
