I was up at this fella today. It's quite easy to find and is just visible from the parking area. The circle is now a sort of elongated "D" shape as a good portion has been chopped off by the old turf road. It's a decent size with some large stones.
Its pretty wrecked and definitely not the best looking circle, but we ain't got many so we love 'em all.
For all your earthly needs check the village store in Gillamoor, it's a happy place.
