Picture: Lough Gill and more !!!
Panoramic Hill Top.
by swoop 28 Jan 2011
Climbed 27th Jan 2011 with my buddy Zocolco.
Amazing views from top looking north , you take in Benbulben , Kings , Copes, Truskmore,
( St.Angleas College- aka Eyesore) KBoy, Benbo and eve Dough in Leitrim. Looking west you see 90% of Lough Gill, Sligo Town Cathedral Spire , Knocknarea , even Ballyconnell head and Raghly in the distance.
Well worth the effort, but a bit off road when you get beyond upper forest level, the heather is knee high in places , and makes for slow progress. Also alot of bog holes , and sudden drops on the palteau, good light is required for safe trek. Approx 297m+ at summit. It was a relaxed
3 hr round trip, not difficult, just slow. Best panoramic view of Sligo I have seen. St Angelas college is the only eye sore , it should never have got planning , what a blatant mistake. Linkback:

First peak in 2 months
by magnumpig 25 May 2020
Climbed Killerry on Saturday afternoon. Nothing for it but to park in Slish Wood and beat a track up through the scrub. Extensive views from the top of Knocknarea, Benbulben and the Dartrys at large. The Lake Isle of Innisfree is a nice little reward on the path back to the car. Linkback:

Geo on Killerry Mountain
by Geo 29 May 2009
Climbed Friday 29th May 09. This is a hill with the heart of a mountain! From across Lough Gill you see it rise up from the gap created where Slish Wood lies. This is a good spot to start, but there's no obvious way up this one, you follow the forest track to the left out of the car park, then hang a right. We followed this for about a half hour and then as the track doubled back on itself to the left, we thought we were gone too far past the mountain and we would cut up the right hand side of the track and through the trees. A rough deer track helped us us a little, and we kept upwards emerging out of the trees quickly enough at A (G75189 32593). From here it was a matter of fighting our way slowly upwards in generally the right direction through boot leather tough heather. About an hour later we were on the top, marvelling at the views. This hill may be small, but you can see forever. North over the Dartry range and menacing Benbulbin, with Lough Gill in the foreground, inviting you to take a closer peek. Further east over Leitrim's hills, South to the Bricklieve's and West to the rest of the oxen! Beautiful, beautiful, and to think I'm the first to mark it climbed, and first to comment, Brilliant! Thank you Killerry, or Slish if you prefer, you gave me a morning's pleasure, 3 hours of filling my boots with heather seed and a slog down to find the car park again, but you are forgiven, for you are a darling mountain...

Approached this with no definite route in mind, turned out to be the hard option, but well worth it! Cut through the forest straight from the car park and came out onto the mountainside within a couple of minutes. A slog over heather followed to the base of the western face. Came across some deer who made themselves scarce with alacrity. The ascent was very steep, the terrain being solely heather. took approx. 30mins from base then a sequence of false summits before the reward of the view over Gill and north to the Dartry mountains. Descended towards the lough on a flank, passing through a nice, spacious swampy area to emerge on the forest path where it cuts back on itself. Linkback:
