The easiest way up is to take the gondola lift serving the Nevis Range ski area on Aonach Mòr (a height of 650 m above sea level), and follow the ridge joining the two peaks. More traditionally, the hill is often climbed from the south from Glen Nevis. This way the walker avoids the paraphernalia associated with the ski development. Aonach Beag is almost invariably climbed in conjunction with Aonach Mòr.
