The path described by FergalH is now, January 2018, very overgrown. There are many thorn bushes in particular which make it a somewhat dangerous for your eyes. A simpler approach is to park at the disused quarry gate at N24035 43266 C and walk 100m NW along the road to N23968 43330 D where a double locked gate has a sign saying that hunting and shooting are forbidden. So, secure in the knowledge that you are unlikely to be hunted or shot, the well maintained field beyond the gate makes for pleasant underfoot conditions as you ascend to the top of the hill. If you keep close to the perimeter fence of the quarry and then follow the line of the stone wall uphill above the quarry you will come to another gate built into the stone wall. There are two strands of barbed wire to be negotiated then to access the field where the hilltop is located. Linkback: https://mountainviews.ie/summit/1293/comment/19843/
