UPDATE – the car park has changed and is a few yards away from the one we used for the 50th Anniversary Celebration.

Take A3 south and leave immediately after Hindhead Tunnel and follow A333 sp Hindhead and Grayshott. After 0.4 mile, at roundabout, take B3002 left towards Grayshott. After 0.7 mile note the Fox and Pelican on right. From Grayshott head west on the B3002, Headley Road for 0.6 mile and at a bend bear left into Ludshott Common Road.  Turn as if going to Waggoners Wells Road then bear right. It becomes a concrete track.  Car park is on the right after 100 yards or so.
