Coming from the M5 motorway the simplest journey is leave at J8 for the M50. Then get off the M50 at J1, and follow brown signs to the Three Counties Showground. After about 10 miles you reach a set of traffic lights on a crossroads, with the showground across and to the right. Go straight on towards the hills, into a 30 speed limit, then the road bends round to the right. Take the second right and follow the road till it forks, where you take the left fork.
