Burtonwood (near Warrington) - from Burtonwood services (eastbound) go across the motorway on the service road that leads to the other service area, then straight over the new min roundabout and take first left (Wrights Lane). Follow this road until it bears round to the right and there is a track that leads down away from the lane (its actually called Lime Kiln Lane but isn't signposted as such) there is nearly always activity down this track at most times of the day.
