Marko visited (still working on) on 16th Aug 2015 - their rating: Cond: 4 Amb: 4 Access: 3 Half a hill fort is better than none! I intended to visit this site whilst on holiday nearby.Was out on another walk and saw the hillfort,but as i wasn't expecting to visit as soon i hadn't got my notes with me. - Fatal,as i thought that what was actualy a central bank was the South East limit of the fort.Only realised later that i'd missed the chance to see about half of the defences.
However,the half of the hillfort i did see was worth the climb up from Oldcastle.The North West rampart was under bracken but was still impressive (as was the central bank).A modern track runs right alongside the South Western rampart.The North Eastern side is defended by the natural steep slope of Hatterall Hill.
