Hi Fitz, yeah, we were up there yesterday, a really clear morning with no-one else about. I wondered what era the circles date from...there's a group of four what look like kists in one circle and the whole complex is so impressive I was surprised not to have heard of it before, I only found out through the campsite map of the area that it was there.
Thanks for the info, any more would be greatfully recieved.
