This is a heathery bump on the boggy track from Killakee towards Enniskerry. For a direct approach from the W park at the forest entrance O 1413318504 A. Follow track down and around forest edge passing over a bridge. Eventually leave the track and go left steeply up the bank along a narrow rough stoney path leading to an old quarry. Go up and around the left side of the quarry and then up E and then NE along a narrow but well trodden path through the heather. This leads to the top passing on the way between two large and distinctive rock outcrops O 1610518351 B. Near the top the path becomes less distinct before reaching the very striking crags which are a little south of the heathery summit, surveyed to be 555.4m. A walk of just over 6k, over peaty ground, that can be covered between 1.25 and 1.5 hours.
Otherwise reach this summit as part of a traverse including Glendoo and Prince William's Seat. For example Track 2035 Linkback: https://mountainviews.ie/summit/351/comment/5111/
