drive on the A453 past NEMA past the DHL roundabout , up to the traffic lights by Donnington race track , and then turn right.
Drive past the end of the runaway up to the roundabout.
Head towards Donnington village and about 1 mile down the road you will see a pub on the right hand side with a dead end road sign.
Drive down there and you can see the whole field.
Hope that helps
