Beinn Iutharn Mhòr

Beinn Iutharn Mhòr, at 1,045 metres — "Big Hell Mountain" in Gaelic, despite being a rather rounded, unremarkable lump rather than anything dramatic — sits in remote back country well west of Glen Shee, in a close-knit group of Munros alongside Càrn Bhac, Càrn an Rìgh, Glas Tulaichean, and An Socach.

The mountain can be approached either from the south, added as a third Munro to a day from Dalmunzie taking in Glas Tulaichean and Càrn an Rìgh, or from the north as part of a circuit from Inverey via Glen Ey, typically paired with the equally rounded Càrn Bhac. From the south, the connection from Càrn an Rìgh involves a developing traverse path around the northern flank of Mam nan Càrn — initially looking awkward on the map, cutting in the wrong direction before curving back, but proving considerably more straightforward in practice than it first appears, with pleasantly gentle height gain for much of its length before petering out near the final bealach.

From the north via Glen Ey, the route from Càrn Bhac crosses broad, featureless, peat-hagged terrain with only a faint path in places to a col below Beinn Iutharn Mhòr, before a grass-covered slope with a faint path leads to the bottom of the mountain's bouldery north-east shoulder — there's no choice but to tackle the steep, loose terrain directly, though some faint sections of path cut through the scree. Once on the shoulder's crest, easier grass-covered ground and an obvious path lead around the northern corrie to the tidy summit cairn.

Combined with Glas Tulaichean and Càrn an Rìgh from Dalmunzie, the full three-Munro day is around 32 kilometres, typically ten hours; the alternative Glen Ey circuit taking in Càrn Bhac is comparable in length and effort, with a fine cycle along estate tracks to Altanour Lodge shortening the walking distance considerably.

The broad, featureless terrain connecting these summits genuinely tests navigation skills on misty days, particularly between Càrn Bhac and Beinn Iutharn Mhòr — full route-finding confidence is essential given the lack of clear paths across much of this remote back country.

Parking at the Dalmunzie estate drive or near Inverey is free; a daily bus service runs between Dundee/Blairgowrie and Aberdeen/Braemar past the Spittal of Glenshee, and Braemar is served by regular buses for the northern approach.
