Just slightly to north of Carnduncan take the minor road heading west which skirts the north side of Loch Gorm. Pull in at Ballinaby Farm, plenty room.
The huge standing stone is just to the north east of the farm. Follow a well used path up a wee hill and follow some well built dry stane dykes. It is a stunning stone standing 4.9m tall with tremendous all round views west to Saligo Bay, east to Loch Gorm, north to An Carnan and south towards the hills at Turnaichaidh.
Most people turn round at this point, we didn't as in the distance to the north, well hidden, I spied another standing stone.
Canmore ID 37386 (go to Links) estimates the girth of the stone to be 3m at the base, girth being the distance round the perimeter of an object.
Although I didn't measure this on my visit the estimate seems reasonable to me.
Just to the north of the very tall stone at Ballinaby sits another standing stone, originally three stood but two remain. Attempts have been made to move this stone but it still stands. Sadly these attempts have done damage.
It has been broken and now stands at 2m in height, fair enough, but Canmore says the stone is 3m wide, I would say no more than 1.5m. Perhaps something has fallen and it has been removed. One thing for sure was that these stones indicated a safe harbour which there is - Traigh Fleisgein Bheag.
