I followed the river path at Harford Bridge and a cow path up to Tristis Stone. The Chambered Cairn is 70 yards W of Tristis Stone and the Cairn Circle a further 90 yards west.
I followed the stone row downhill (due N) for 220 yards and c. 80 stones when i ran into extensive gorse and lost the trail.
The size of stones in the row varied from inches above ground to three feet.
