Beinn Teallach

Beinn Teallach, at 915 metres, is the lowest of all the Munros — for many years regarded as a high Corbett below the 3,000-foot threshold until a 1984 resurvey confirmed its true height and promoted it onto the list.

Almost always climbed together with neighbouring Beinn a' Chaorainn, the route starts from Roughburn on the A86, following forestry tracks before crossing the Allt a' Chaorainn — best done at the point where the river splits into two tributaries, or via an alternative east-bank approach if the river is in spate. From the bealach of Tom Mòr, marked by a cairn and old fence posts, the route heads up below crags on wet, grassy ground that dries out higher up onto a worn path, climbing a gentle, pleasant ridge with fine views over Loch Sguadaig towards the Monadhliath. Two cairns mark the top: the true summit is the first one reached, with a second, allegedly slightly lower cairn a short distance further west.

From the summit, the descent heads south down easy slopes before curving to rejoin the Allt a' Chaorainn lower down, crossed again via a deer fence gate, with a faint, often soggy path leading back down the glen to the forest track and Roughburn.

The combined horseshoe taking in both Munros from Roughburn is around 13-18 kilometres, typically six to eight hours; Beinn Teallach on its own, approached directly, is a considerably shorter and gentler day, well suited to those wanting a more modest introduction to the range.

Despite its modest height, this remains genuine mountain terrain with pathless, often boggy sections and a river crossing that demands care after rain — the walking itself is comparatively gentle once the bealach is gained, but full navigation and appropriate footwear are still worthwhile given the lower slopes' reputation for bog.

Parking at Roughburn is very limited, with a layby around 300 metres east holding a handful more cars; there is no public transport to the start.
