It was never a road, just a path, and it was more like fifty years ago than seventy. It fell into disuse after the new path was signposted and gradually disappeared, though if you look carefully you can still make out its faint course. There is even a piece of handrail in the woodland beyond the cache!
This cache has been placed by kind permission of the National Trust, close to the start of the old path through the woods. The NT Manager asks that you rejoin the main track after finding the cache, not continue through the trees.
There is nothing at the published co-ordinates. Instead, let his (whose?) date of birth be AB/CD/EFGH. The cache is located at N50 4A.G(F-E)H, W002 5B.CH(A+C). Be aware that tree cover may well distort GPS reception. An OS map will show the obvious parking at Langdon Hill.
This cache can be combined nicely with 'Mike's 60th' and 'The Golden Gate' (both placed by us). It's also on the route of the Golden Cap Estate series placed by NT West Dorset.
