You can park outside the chapel in the hamlet of Rhos-Goch. The barrow is in the field behind the chapel.
At first I walked through the chapel graveyard in the hope of seeing the barrow in the neighboring field (the graveyard is on a slight rise). However, due to the high hedgerow this was not possible. I then walked a short distance down the main road and came to a field gate.
Unfortunately I could see no trace of the barrow.
Either I was looking in the wrong place or it has been ploughed out?
