Aghla Beg

About Aghla Beg

One of the more remote members of Donegal’s Seven Sisters, this quartzite peak sits in the heart of the Derryveagh Mountains. Positioned between Muckish and Aghla More, its summit offers a wild, unpeopled perspective of Lough Altan and the rugged glens that define this Atlantic-facing corner of Ireland.

Did You Know?

• •The name is an anglicisation of the Irish Eachla Beag; while Beag means small, Eachla is thought to refer to a rocky ridge or a place where horses were kept.
• •It forms part of the 'Seven Sisters' chain, a popular but demanding high-level ridge walk that includes Errigal, Mackoght, Aghla More, Ardloughnabrackbaddy, Crocknalaragagh, and Muckish.
• •Looking north-east from the summit, walkers are treated to an exceptional profile view of Muckish Mountain, highlighting its unique 'table-top' shape and the steep ramps of its mining tracks.
• •The mountain is primarily made of Dalradian quartzite, which creates the distinctive white scree slopes seen throughout the Derryveagh range, often shimmering like snow in bright weather.
• •Being the 'small' sibling to Aghla More doesn't make the approach any shorter; the local terrain is a masterclass in how many hidden bogs can be squeezed into a single hillside.
