Fairly easy to access. You can drive most of the way up the hill and park below the ‘pimple’. A fairly short but steep path will take you to the top. Through the defensive ditch and up the steps onto the top. You can see for miles on a clear day. Unfortunately when I visited it was like ‘pea soup’ and I could only see about 20 yards!!
A group of local people are setting up a society for the preservation, protection, and promotion of this ancient site.
