I approached from the opposite side of the hill that Thelonius tackled.
Parking at the end of Keir Hill Road, Westhill I walked up the farm track, north, which veers east towards Berryhill Farm. Just before the farm I jumped the fence and headed to the top of the hill with its impressive enclosure. The entrance to site is to the east with the width of the enclosure being well over 30m.
After a good look round it was further east to the Souterhill cairn, heading back to Keir Hill Road via Souterhill and Berryhill farms.
