That's the title on the visitor information board at the start of the line of the old A3 which used to run along the edge of the Devil's Punch Bowl just here. You can see it curving round to the left in the distance.
Now replaced by a tunnel, the old road has been dismantled and is now demoted to Bridleway status.
Pictures from a few years ago show it as a wide sandy ride
SU8935 : Former A3 Road, Hindhead, Surrey but I have to say we found it very muddy and heavy going, as shown here. Overused and poorly drained, it is in worse condition than a lot of the older tracks on the common, although the views are splendid.
