Coomachuillin (The People's Crag)
This crag is in the Glenbeigh Horseshoe and it overlooks the south shore of the small lake called Lochachuillin in the hanging corrie south of the main Coomasaharn Lake. The crag is composed of compact sandstone, is very steep and protection is difficult to arrange. The crag has been referred to as 'The Peoples Crag'. See Sheet 78 OS Discovery series. GR V 625 826
Furriskey 350ft. HS Three gullies split the crag: this route follows a line up the L of the buttress to the R of the central gully.
Start: at a cairn below a steep slab.
1/. 40ft. Gain the slab on the L. Move R and continue to ledge on top R of slab.
2/. 30ft. Up a short slab then easy rock to a grass ledge.
3/. 120ft. Climb the wall above, mostly on the R. Cross the grass rake (about 40ft) to belay in a corner 20ft below a large square overhang.
4/. 20ft. Pull out R - awkward - and continue up to belay just under the overhang. Peg in place.
5/. 60 ft. Climb the groove on the L. Move slightly R and continue to belay in a dark corner on a long sloping ledge.
6/. 80 ft. Move out R - delicate - to a small R-ward sloping slab. Climb this and continue up the groove above. Fine situation.

2/. 30 ft. Continue up to R-hand end of large overhang.
3/. 90 ft. Traverse L underneath overhang (peg runner). Exit on L-hand end of overhang. Climb up to foot of R-ward slanting slab. Belay here.

Above and to the R of the three main buttresses is another large area of rock. It is separated from the main crag by a wide, steep gully, sloping up from R to L. This buttress has two faces, set at R-angles to each other, the R-hand black and overhanging, the L-hand less steep but undercut at the bottom.
Tradesman's Entrance 220 ft. VS (mild)
Below the undercut L wall a slab slopes up R-wards into the angle between the two faces.
Start at the bottom of this slab.
1/. 120 ft. Move from L to R across the slab to climb thin cracks to a grass ledge. Continue up a deep narrow chimney in the centre, and on to the top. Huge pinnacle belay.
2/. 40 ft. Climb the corner for about 20 ft. Make a thin foot traverse L to gain the obvious L-sloping ramp. Move up a few feet to a little bay.
3/. 60 ft. Continue up the ramp to the top.
