Aonach Mòr and Aonach Beag by Coire Giubhsachan from Glen Nevis

The walk starts from the car park at the end of the Glen Nevis road. The path goes through the Nevis Gorge to the meadow below Steall Falls and on up the glen to a footbridge over the Water of Nevis, at 228 m. From there paths climb Coire Giubhsachan between Aonach Mòr and Càrn Mòr Dearg to the bealach at 831 m. A steep path climbs from the bealach to the plateau of Aonach Mòr, 1,220 m, and the path goes on south along the plateau to Aonach Beag, 1,234 m, the higher of the two. The return is the same way.

It is 19.3 km with 1,476 m of ascent; allow about 10¼ hours. The grade is Strenuous: a very long mountain day with a steep climb and descent.

A longer round of the two hills also climbs by Sgùrr a' Bhuic and Coire nan Laogh, but the paths mapped on OpenStreetMap stop short of that side, so this route goes up and down Coire Giubhsachan instead. The plateau needs careful navigation in cloud. The gorge path is rough, with steep drops beside it. South of the ridge is John Muir Trust land, where the stalking tables list no stalking issues.

Highland Council approved pay and display charging at the car park at the end of the road in May 2026, hoped to start in June or July 2026. It was free before then, so check the machine on arrival. Fort William station is about 8 km away.
