Park at Ballyduff graveyard, Q54076 10104 A , room for 10 cars.
Walk back towards the R560 from the graveyard and turn right. Walk around 500m along the road and cross the bridge over the Glennahoo River. Take care while walking along the R560 as it is a busy road with no verges. After crossing the bridge, continue along the R560 for another 300m. Leave the R560 and turn right into a track at Q5460010350 B . There is an old farmhouse with dormer windows and a sloped flat roof extension at the track entrance. Continue south-eastward for around 150m along this track to reach a T-junction.

Turn right there and follow a lane southwards to Maghanaboe at the head of the valley. The Glennahoo River twists and turns along the valley floor to the right. The narrow valley, some 3km long, is flanked by a sweep of steep slopes clothed with banks of scree. Go to Beenbo first and then cross from there east to Slievenagower.

Note: We no longer recommend going on the ridge immediately south of the graveyard because of access issues however if you approach the landowner there you may get permission. Linkback: https://mountainviews.ie/summit/500/comment/5259/
