These are a bit awkward to get to. Follow the A94 through Scone towards Shianbank, take the small road on the southern side towards the house at the end of the track. The circles are in the small wooded area out in the fields. There are the remains of what appear to be old WW2 bunkers beside the site, and a very large rabbit warren! According to a friend (Scotty) there is evidence of wierd rituals being held on this site - he saw the usual candle debris, a large cow skull and a cat's tail last time he visited, approximately September 02.
