I went there about 2 months ago. It was a bit of a search, so I hope I remember the details.
That said, the search is part of the fun.
General directions:
- Rent a car
- Head out to Athlone, on the M6 out of Dublin (about 120 kms)
- Take exit 9
- Moydrum road is just north of the highway to the west (first to the right) , take that road.
Now it's getting harder to remember. You're getting close, but the castle isn't on this road, nor seen from it.
- After Moydrum Road has taken a bend to the left, look for a (tiny) road on your right.
- Take that road and follow it (keeping left). You'll now probably approach the castle from the back. It's where the road takes a 90 degree turn to the left (with on the right the entrance to a farm or so).
We approached the castle from the other side, having followed Moydrum Road a bit longer, until that one took a turn to the right. Then we took the first road to the right, uphill, and once we were going downhill we took a road to the left, driving straight to it.
I think this is the location of the castle on Google Maps:

And just because it was one of the highlights of my holiday in Ireland, here's a picture of it how it was 2 months ago.
And oh, I TOUCHED THE CASTLE!!!
(the castle is on private property, so you can't just wander around it though)
