I parked here http://www.streetmap.co.uk/newmap.srf?x=266215&y=86555&z=4&sv=266500,86500&st=4&ar=Y&mapp=newmap.srf&searchp=newsearch.srf (where the yellow road meets the white track)
From here you can easily easily walk to Shovel Down and then across the streams to Scorhill. There are lovely clapper bridges over the water.
