Creag Mhòr (Meall na Aighean)

Meall na Aighean, at 981 metres — "Hill of the Hinds," also long known as Creag Mhòr on older maps and pre-1997 Munro's Tables editions — is the fourth and final Munro of the Glen Lyon ridge circuit above Invervar, its summit a small tor about half a kilometre east along a broad plateau.

Reached from Càrn Mairg via a faint, sometimes indistinct descent path — requiring attention to map or GPS to avoid a few false lines — the route crosses a bealach before climbing steadily south to the summit ridge. The true summit tor offers contrasting views: the great arc of mountains around the north, west, and south relenting to considerably more rolling countryside to the east.

Alternatively, Meall na Aighean can be approached first (in an anticlockwise circuit) directly from Invervar, following a faint path up the western shoulder over grass and heather, with the option to bypass the mountain's own south-west minor summit before continuing over the plateau.

From the summit, the descent heads north, eventually curving east-north-east to reach the bealach at the foot of An Sgorr, from where the circuit continues (in reverse) back towards Càrn Gorm, or, having completed the full round, back down to Invervar via the standard descent route off Càrn Gorm's south-east shoulder.

The full four-Munro circuit — Càrn Gorm, Meall Garbh, Càrn Mairg, and Meall na Aighean — from Invervar is around 22 kilometres with roughly 1,476 metres of ascent, typically eight to nine hours; reaching this final summit after the technical challenges of Càrn Mairg brings a welcome sense of the hardest climbing being behind for the day.

Though less demanding than Càrn Mairg, the connecting terrain still requires genuine navigation confidence, particularly on the initially indistinct descent path from Càrn Mairg — full route-finding skills remain valuable across this broad, exposed ridge.

The Invervar car park is small and fills quickly; overflow parking is available around 1 kilometre further up the road. There is no public transport to the start.
