Turn left along the road very briefly, then cross it to join an engineered path heading towards Quinag. The mountain is owned and managed by wild land conservation charity the John Muir Trust ( www.jmt.org
). For the return leg note a signed path detour designed to reduce erosion damage. The built path surface ends before Lochan Bealach Cornaidh but the trail continues very obviously just north of the loch, climbing to the Bealach Chornaidh.
At the bealach take a narrow path northeast on a rising traverse across a steep hillside to reach the col between point 745m and Sail Garbh. The broad rocky ridge crest leads up to the trig point on the summit of Sail Gharbh. Most of Quinag is made of sandstone, but the very top slice of its highest peak is quartzite; the division between the two is very clear.
Retrace your steps to the col, then go towards point 745m. Just before the last climb to this minor summit bear right, traversing the hillside to pick up an eroded path that descends northwest into a little col at the start of the ridge connecting to Sail Ghorm. Ahead is a steep-sided minor summit with a distinctive sawn-off top; a path traverses its right flank. Beyond this, continue along the crest over a lower, less defined top, and past the head of a dramatic gully on the left. Then it’s an easy ridge-top stroll to the summit of Sail Ghorm, Corbett no.2.
You're at a dead end here, so backtrack along the ridge. In passing it is worth climbing the un-named sawn-off summit. From the little col beyond this feature go back up the eroded path towards point 745m, this time continuing right to the top. Though it lacks a name, this little summit is the pivotal point in the middle of the Quinag range. From here a path drops quite steeply into the Bealach a’ Chornaidh. Continue south for the lung-busting pull onto yet another excellent-but-un-named summit, point 713m (714 on some maps); the final climb takes you along a grassy knife-edged ridge. An easier descent now leads to a level col. Pass a tiny lochan and continue up rough rocky ground onto the summit of Spidean Coinich. This is Corbett no.3, and arguably the best of all Quinag's tops, with a spectacular north face.
On leaving the summit bear briefly south at first to avoid a steep gully that cuts in on the left. Once this is passed trend more southeast to follow a well-used line down steep rocky slopes into a broad col. Climb over a minor top and continue down the mountain’s rocky east spur, following the edge of a line of small cliffs. Towards the base of the hill look left for the new approved route (as mentioned in stage 1) which leads north past a small lochan to rejoin the approach path.
