There are decent views from the top considering it's only 300m, the obvious route is from the NW via a field which can be accessed via a gate on the 'main' road. Access from the south via the forest isn't possible as far as I can see (see my gps track for my attempts). Linkback: https://new.mountainviews.ie/summit/1121/comment/15365/

Pookeen is a short but brutal hike. In the 10 years since thomas_g commented, the 'field' he referenced is now full of densely packed trees. I found another gate further along the road and took what looked like a track. If hiking through thick overgrown brambles, prickly bushes and sharp sitka spruce is your thing then you'll love this one. I only ploughed on to the top as it is in my local 100, so had to be done. I have so many thorns in my skin that I look like I have Chicken Pox. Avoid if you can. Linkback: https://new.mountainviews.ie/summit/1121/comment/24376/
