In reply to 2E0XTL: An easy route, but is does get a little indistinct beyond the disused mine at 795857. There are a few visible remains there and it is perhaps interesting to speculate what the scene looked like when the mine was working, and how long ago that was.
An alternative descent route is to follow the ridge S to the edge of the woodland, (there has been some fencing work done here in the last few years), skirt the woods heading SE and later S to pick up a track descending E past another disused mine site (little evidence here, now) back to the farm.
Be carefull of the route past/through the farm. This has changed several times in the last 5 years, and last year certainly wasn’t as shown on OS Getamap now.
I don’t use the car park you mention. Just to the E on the A44 (perhaps about 808840) there is an extensive layby, but if you park too close to the mobile tea-bar he may get a little upset, if he’s there now.
Looking at the database, I’m very surprised to see that no-one has claimed any activation of this summit since mine (as GW6DTN/P) last June!
