Visited on 31.08.03. There are several paths running through this little woodland, best thing is to park in the layby on the right-hand-side of the road to Bodsham where the public footpath sign is pointing along the edge of a field, but instead of walking down that footpath walk up the road, past a cottage, to the bridleway and turn right down there, we're pretty sure we found it - about a 5 min walk and set back from the right hand side of the track.
The barrow is quite large around 50 ft long and 2 meters high but very overgrown by trees and other assorted undergrowth. It felt great to find it but I can see why JC would have chosen Julieberries Grave for the book over this site. The entrance would seem to be at the track end of the barrow but there aren't really any specific signs of this. There's a large burrow, badgers? dug deep into the top of the barrow about half way along and is about the only spot for sitting down.
