Stob an Aonaich Mhoir
Stob an Aonaich Mhoir is a quiet 855m Corbett on the east side of Loch Ericht, deep in the Ben Alder Forest. It sits across the loch from Ben Alder itself and is rarely visited compared to its Munro neighbours; most parties tackle it as a bike-and-walk expedition rather than a single day on foot. The summit is a small rocky outcrop on a long heathery ridge, with a striking view west across Loch Ericht to the cliffs of Ben Alder's east face.

The most direct line uses the locked estate road south from Dalwhinnie along the east shore of Loch Ericht for around 12km — a long flat bike ride to the foot of the hill at Ben Alder Cottage area. From there a track climbs east before peeling off onto open heather and grass to the summit. Around 15km/752m of ascent for the hill alone; total bike-and-walk day is 35–40km. Alternative approach from the south via Bridge of Gaur is similar in length.
Terrain
The Loch Ericht estate road is a well-graded gravel surface — ideal for bikes. Off the road the hillside is open heather and grass with no path; the climb to the ridge is gentle but slow over peat hag. The summit ridge is broad with the rocky outcrop at the high point hard to spot in mist among the surrounding bumps. No exposure or technical ground.
In winter
A surprisingly committing winter day because of the distance. The estate road is exposed to easterly winds funnelled down Loch Ericht. Bikes are not feasible under snow. The hillside itself is benign — no avalanche concerns or cornices — but the long return in fading light is a real consideration. Dalwhinnie is reliably accessible by car and train.
This hill is in the Creag Meagaidh SAIS forecast area. Check SAIS forecasts in winter (December–April).
