Superior Road car park is on Ludshott Common road approximately at the place marked by the purple circle to the left of the G in "GRAYSHOTT CP".
The surface of the road is concrete and there are broadly 2 areas to park cars, each with enough room for 30 cars.
There are no charges for the car park; it's free!
This photo shows the Headley Road driving out of Grayshott towards Headley. The left turn is marked for Waggoners Wells; however to get onto the Superior Road car park you want to head across Waggoners Wells Road and go down the track immediatley to the left of the "sharp deviation of route" chevron sign; or those white >>>> set against a black background.
The surface will change to concrete and there are 2 signs to look out for, the first is next to a small area to park cars, but this is NOT the Superior Road car park.
The second sign marks the start of the Superior Road car park.
For those of you that have been unable to find any useful reference to Superior Road, I did find it by accident on a Garmin TopoActive Europe 2021.20, West map.Â
