A tricky ascent as this hill is surrounded on 3 sides by farmland and on 1 side by windfarm construction. I ascended through farm land (less than ideal but didn't meet anyone) from W36490 78617 A where there is room to park 2 cars on the roadside.
Note: although I went up this way , it may not be possible at some future point as there appeared to be a house being constructed at the access point to the fields. No restriction on access from point W3813178642 B as oh Sept 2015. Linkback: https://mountainviews.ie/summit/867/comment/5626/

Burren has been nagging me for a while, I kept seeing it on my profile, the closest hill to you is Burren and you haven't climbing it yet: so I did what any sensible person does, waited for a truly miserable day after several days of rain with poor visibility to 'enjoy' my trip to the top.
Being an avid student of the interweb - I found an interesting track from the north that promised a mere 700m of walking to bag my closest hill. Starting at the Burren power track at W38078 79548 C (loads of room to park), I spent 5 mins being very pleased with myself that I'd found a easy way up on what was a pretty unpleasant day, then the track missed the summit and kept going - that wasn't in the plan. So there was nothing for it but set the GPS and head straight for the summit: 25 minutes of misery pushing through soaking wet, knee and sometime waist-high prickly bushes later, I finally found the trig point. If you must do it this way (I assume Jackills way is easier) I suggest you turn off the track at W38004 79020 D and head up a steep track, when the track stops by the power poles, put on your gaiters and head almost due west - enjoy!
The upside: the 2km round trip took about an hour and warm tea cures all.
Update: Now my profile says closest unclimbed: Coolsnaghtig, Jackill says "a high point in the bog next to an overturned tree stump" - oh joy... Linkback: https://mountainviews.ie/summit/867/comment/14696/

From some angles Burren I think could be an interesting lump.
Unfortunately on the day of my visit it was covered in fog and drenched in spitting rain.
I had intended to ascend from the east on the track at W38131 78642 B but found this whole side of the mountain peppered in "private land" signs. Instead I made a some what longer ascent through farm land (less than ideal but didn't meet anyone) from W36490 78617 A. As of October 2009 there was evidence of lots of windfarm activity around adding to the challenge of access.
I passed an interesting memorial underneath Burren at Bawnmore crossroads. It commemorates a soup house that operated near the cross during the great famine and remembers all those who died during that time. Linkback: https://mountainviews.ie/summit/867/comment/4224/

Had to do as it was in my local 100 list, but wouldn't recommend unless you enjoy chest high heather and prickly furze. My dog disappeared completely in the undergrowth. Still, nice view from the top. Linkback: https://mountainviews.ie/summit/867/comment/20821/
