[RWD version 1 ] This is the 'standard' route to Slioch, the huge mountain visible across Loch Maree in the NW Highlands of Scotland, and is a fair indicator of the difference between walking in that area and walking in Ireland.
While actually pretty straightforward compared to nearby peaks such as the Torridonian giants (brutal steepness, exposed scrambling) or the summits in the Great Wilderness of which it commands magnificent views (hilariously vast distances to cover), it should be born in mind that this route involves a walk of the best part of 7km to reach the bottom of the mountain, and once you're there it's a long grind from practically sea level to almost 1000m (although there is a path for most of it).
Still, highly recommended and a good introduction (assuming decent fitness!) to one of the finest hillwalking areas in these islands.
