Short Summary created by Harry Goodman  22 Nov 2011
For a direct climb of this hill go left off the R251 at B908 205 starA and find a suitable parking place off road. Walk down the road and cross the bridge between Dunlewy Lough and Lough Nacung Upper. Follow the road S and then SW to cross over the Stuhannameel (stream) B902 189 starB. Leave the road and ascend up the hillside SW to Pt. 352, B896 179 starC. Continue up S, passing around tiny L. Croreagh and on up to Pt 455, B896 170 starD and then 200m further along Pt 471, B896 168 starE. Once there go SW for 500m to the top B89230 16636 starF. From the bridge between the two loughs it is some 7k out and back. It is also possible to extend the route and take in Crocknafarragh SE Top and Crocknafarragh. Out and back adds just over over 3k to the walk. Linkback: https://mountainviews.ie/summit/487/comment/5246/

An excellent vantage point
by Harry Goodman  12 Aug 2010
I climbed this hill on 10 August as part of a round of five tops which I had not previously visited. My approach was from Crocknafarragh SE Top B8842416451 starG (see report on this hill for earlier part of route). The going was easy and after crossing the saddle I was soon up at the stone coverd summit area marked by a very large boulder bedecked by a small cairn of stones B8923016636 starF. I had fine views NW across Lough Nacung toTievealehid and N to the fine cone of Errigal. SE across L Atirrive Little and its bigger brother L Atirrive was the formidable and dominant bulk of Slieve Snaght and other lower tops in the Derryveagh Mountains. An excellent spot to sit and simply enjoy the surroundings. From my vantage point I noticed a fine ridge running NW over Pt 471 and then more or less N down over two more spot heights that could be used for ascent and /or descent of Crockglass from a track B900189 starH above Dunlewy but would add that anyone considering the route would need to ensure there is no impenetrable forestry blocking the way. As for me the fifth and final hill in my round, Addernymore, beckoned and I set off in pursuit of same. Linkback: https://mountainviews.ie/summit/487/comment/6006/
