Aonach Beag and Aonach Mor are the two highest peaks on a long ridge running N-S from the Great Glen to the head of Glen Nevis. The sides of this ridge are generally steep and craggy and it is best to assume that you should only attempt an ascent or descent from the N or S ends of the ridge. As the N slopes of Aonach Mor are developed for skiing, it is normal to ascend both these mountains from the S via Sgurr a'Bhuic. An alternative route leads up Coire Giubhsachan to a high col (830m) between Aonach Beag and Carn Mor Dearg. Whilst an ascent of this path is relatively easy, it can be difficult to locate when descending and any deviation will lead you to dangerous crags. If in doubt avoid this route.
Moderate climb with some steep ascents and many crags either side of the summit ridge, Navigate with care. Excellent views of Ben Nevis and Carn mor Dearg.
A strenuous route in places with short sharp ascents but relatively easy. Care is required in low cloud to attain the narrow ridge between Aonach Mor and Aonach Beag.
The route along the Allt Coire Giubhsachan can be very boggy in wet periods.
