Aghla Beg

About Aghla Beg

Rising within the rugged Derryveagh Mountains of Donegal, this prominent quartzite peak forms part of the celebrated Seven Sisters chain. Positioned between the massive bulk of Muckish and neighbouring Aghla More, it offers a stony, heathery ascent rewarded by dramatic views over the deep, dark waters of Lough Altan.

Did You Know?

• •The name derives from the Irish 'Eachla Beag', with 'Eachla' likely referring to a place of horses or a craggy ridge, and 'Beag' meaning small, to distinguish it from its slightly taller twin, Aghla More.
• •The hill is a key component of the 'Seven Sisters' ridge walk, a demanding Donegal circuit that connects Errigal, Mackoght, Aghla More, Aghla Beg, Ardlougher, Crocknalaragagh, and Muckish.
• •Below the mountain’s southern slopes lie the ruins of Altan Farm; located on the shores of Lough Altan, it was famously abandoned during the mid-19th century and remains one of the most remote ruins in the county.
• •The summit offers an exceptional vantage point for studying the 'Glover’s Alley' route on the neighbouring Muckish, as well as clear-day views across the Atlantic to the lighthouse on Tory Island.
• •Despite being officially designated as the 'small' one, the 602-metre summit is high enough to ensure you still get the full, unadulterated Donegal experience of horizontal rain.
