Wonderful views down Kenmare bay on a fine day. Be aware the ground below the summit is very boggy and pools of water abound.
The best access is via the Kerry way from Gowlane V917 752 A (skirt Peakeen to the N). While access is possible from the Molls Gap road via the col between Peakeen W and spot height 525m: there are access issues to Derrygarriff to the west of Peakeen, so the western approach is probably best avoided. There is no real sense in approaching from N (unless you want a longer route via the old Killarney to Kenmare route).

There is a good approach from the SE, via Peakeen itself - see Peakeen short summary for details. It's about 1.3km from Peakeen to the summit, mostly grass or short heather, a bit boggy in places, but the climb is simple enough - probably about 80m ascent. The summit is undefined - a sort of grassy area. It took about 45 minutes to make the traverse. Linkback: https://mountainviews.ie/summit/374/comment/5133/
