Tremendously impressive ditches and banks on this large site, unfortunately, as others have mentioned, you do need decent weather up here.
We were greeted by a ferocious gale which made exploring the site very difficult and one wonders how the original inhabitants dealt with inclement weather.
Any future research and/or excavation here should be very interesting indeed, if, as noted, much of the site has never been ploughed.
Access Small layby to the SE. Short level walk to entrance, gate, modest slope to interior.
