A place to just sit and enjoy. .. by group   (Show all for An Cnoc Glas) Picture about mountain An Cnoc Glas in area Donegal NW, Ireland
Picture: Summit rock on Crockglass with Slieve Snaght in background
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 G (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 F. 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 H 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:
