A dumpy little 0.93m tall lump of basalt, perched on top of a little hill, overlooked by Knocklayd mountain. Not as impressive as the other standing stones in the area, but quite easy to find, and with great views to the west.
From the Round Tower at Armoy, head east, straight ahead at the crossroads, and take the second (concrete) lane on the left. (There's a little house at the bottom of the lane used to store wheely-bins) Just after a sharp turn in the lane, the road heads straight through a farmyard. The stone is directly behind the barn.
The stone is easy to pinpoint from the OS map, but I didn't spot it until speaking to the local farmer.
