Park at a small field entrance at R94525 53427 A (Point A) on the narrow roadside where there was room for only one car.Walk back up the road towards Hollyford and cross the first gate to your right.
Be aware this is farmland so access may not always be possible so if you can ask the farmer.
Follow the fence/ditch on the left, initially next to a tree lined stream, crossing two fences and a farm track to the summit of Lackeenacreena which is marked by a few stones next to a wire fence.
Cross the wire fence onto a forestry edge track, follow this downhill, when it turns sharply right do not follow rather cross the fence in front to you and continue on across farmland.
Cross a tree lined ditch and then gently uphill to the summit area of Glenaneagh and its windmill.
Head downhill to the south east from here to the field corner on the left, cross the fence to a rough, muddy track end. Follow the edge of the forest uphill still going south east.
When you reach the field corner the summit is just up the forest track to your left.
I'm afraid Glenough Windfarm completely dominates this top with a roadway joining the adjacent 2 tops. Access from R955 542 B. The actual summit is beside the windfarm control centre and roadways. Linkback: https://mountainviews.ie/summit/712/comment/5471/

Climbed Ring Hill on 27/04/08 as part of a small ring walk taking Lackenacreena and Glenaneagh along the route. This hill offer no challenge. On the plus side, it does offer a fantastic view of the Galtee mountains. Nice sunday afternoon stroll. Linkback: https://mountainviews.ie/summit/712/comment/3075/

I did this as part of a double bag with Glenenagh (see my comment there for approach.) From Glenenagh proceeded down grassy slope past turbine, easily ducked under a solitary, possibly electrified, wire and then simply followed the wind farm track NE and then SE all the way to the summit area some 2km away. I located the high point to the left of the turbine area, up another track, where there is a pile of stones on top of an earthen bank (although my GPS indicated that it was on the other side of the track). 2 hours to do both hills.
