Beinn a’ Ghlò Circuit

Beinn a’ Ghlò Circuit is a roughly 22 km (13.75 mi) loop from Loch Moraig over Càrn Liath, Bràigh Coire Chruinn-bhalgain and Càrn nan Gabhar, returning around Beinn Bheag to the same start. The full circuit is listed at 1,239 m of ascent and 8–10 hours; plan a mountain day. This version of the circuit returns beside the burn from Bealach an Fhiodha. Shorter published figures describe a different descent via Airgiod Bheinn.

The distance, climb and rough ground make this a strenuous outing, despite clear paths on much of the ridge. Expect steep drops between summits, exposed open terrain and a tiring final climb. In cloud, navigation from Bràigh Coire Chruinn-bhalgain toward the next bealach is difficult; one described path fades before a steeper eastern descent. Carry a map and compass and know how to use them. The return is boggy and crosses burns several times. No food or drinking-water facilities are reported along the route.

Start at Loch Moraig car park beside the end of public Monzie road, before the cattle grid; parking beyond it is prohibited. Walk briefly along the road, turn right through the gate by the plantation and follow the estate track for about 2 km. A grassy fork and fence gates lead toward Càrn Liath. Pitched stones cross wet ground before a steep climb up a repaired erosion scar. Pass old grouse-butt remains and a large cairn; the true 975 m summit cairn lies beyond the trig point.

From Càrn Liath the path follows an undulating ridge, curving around rises before dropping to a bealach. The next climb eases around a scooped corrie to Bràigh Coire Chruinn-bhalgain’s summit cairn. From here, keep track of the line in poor visibility: route descriptions either cross the minor summit east of point 1016 m and follow the plateau edge, or skirt left on a path that fades before a steeper descent joins a clearer track lower down.

Descend about 150 m to Bealach an Fhiodha, then climb by a rising traverse onto Càrn nan Gabhar. The gradient eases along the ridge, but the ground becomes stony. Pass the prominent earlier cairn and the trig point; the true summit is the well-built cairn farther along, at 1,129 m. It is the highest of the three tops, with views toward the head of Glen Tilt. Retrace to the bealach rather than continuing over Airgiod Bheinn.

From the bealach, descend beside the burn. The lower path becomes boggy, and the described line crosses to clearer tread on the opposite bank. Cross the burn twice more and then Allt na Beinn Bige. A better-built path contours around Beinn Bheag to an estate track; pass through a gate and rejoin the outward route near the hut below Càrn Liath. Retrace the opening track and road to Loch Moraig. Keep time and energy for this long finish.

The wider Beinn a’ Ghlo conservation area includes alpine heath, species-rich grassland, limestone slopes and tufa-forming springs. Its records include rare montane plants such as yellow oxytropis and mountain avens, but these are landscape-scale records, not promised sightings. The walk itself shifts from a repaired pitched path to open ridges, stony summit ground and wet lower burns.

Loch Moraig has about 60 parking spaces and no toilets. A parking charge may apply; check current terms before travelling. No food or water stop is reported at the start or along the route.
