Not too hard to find assuming you've got a map, the first inkling that you've arrived is catching sight of Clach thingy wotsit down the road, park there by the standing stone and kerbed cairn they're all in the same field, or just go straight to Strontoiller farm.
Aubrey Burl says there are still 31 stones, but I don't think I counted that many but he was right about the western arc being best preserved, the circle is fairly ruined but still obvious as such, not intervisible with the big stone and kerb cairn as there are what looks like glacial moraines between them. Standing on top of one we can look down on the circle just as I was doing that very thing my mum called me on the mobile, a first, and freaky little thing. Just across the field I can see Loch Nell shining in the sun, another glorious day, Scotland must like me, and I like Scotland.
The circle stands in a field on the left of the road but can be seen better from the track leading to the farm. I was attracted to the standing stone and saw what I thought were sheep in the far end of the field, these turned out to be the low circle in the long grass. It was very wet and squeltchy, I was not equipped for bog walking so I took the photo from the track. The circle is about 20mtrs in diameter.
Next to the Standing Stone is a small kerbed cairn.
