I visited this site a couple of years ago on the way home, in the pouring rain as I remember. I parked at the field gate on the minor road to the south of the Hillfort and took the short uphill walk through the field (not public right of way).
I remember the whole site being heavily wooded.
However, the main thing I remember is when coming down back to the car, jogging as you do to try to stay on your feet on the wet grass, my foot got caught in a piece of wire sticking out of the ground. How I managed to stay on my feet I don’t know! I think a re-visit is in order – on a dry day!
