Approach from the East by parking at Q809 107 A and follow the Dingle way for 3 km to Q77992 10599 B for a direct steep ascent through knee high heather to Q77504 09568 C where the gradient becomes less steep up to the summit.
From the West park near Derrymore bridge at Q74224 10770 D (parking limited) and follow Dingle way to the Derryquay river at Q760 105 E and ascend in a SE direction to the summit Linkback: https://mountainviews.ie/summit/263/comment/5023/

Made the mistake of coming in via the boreen to 791 107 F. As the map says, it does go out to open country, but it's very boggy and overgrown, and the gate at the exit is both fixed shut and not load bearing. Climbed carefully over the gatepost to follow the Dingle Way west to the next stream. Traces of path go up the far bank, but the ascent up the hill's NE shoulder is on very steep man-eating heather, chest deep in places! To add insult to injury it was almost too windy to stand on the top, so continuing to Baurtregaum seemed a bad idea. Descended directly N to the Dingle Way, much easier ground than the way up. Should have read Simon's description above before rather than afterwards really. Linkback: https://mountainviews.ie/summit/263/comment/18731/
