I've been here many times and never once have I taken a satisfactory shot of the place. It's on the left-hand-side of the track that you take to get to Ballymaice passage grave.
The forestry is planted very close to the edge of the ditch of the rath, but the west arc of the site is the most visible. This is yet another of those sites that I'd love to see cleaned up.
