Slieve League [Sliabh Liag]

Rising almost sheer from the Atlantic, these dramatic cliffs offer a wild, salt-sprayed alternative to more commercialised coastal spots. The terrain transitions from boggy moorland to the vertigo-inducing One Man’s Pass. This Marilyn provides an exposed, exhilarating walk with vast views across Donegal Bay toward the distant Sligo mountains.

• •The name Sliabh Liag translates from Irish as 'Mountain of Stone Slabs'. This refers to the massive blocks of quartzite and shattered scree that define the summit, distinguishing it from the softer, peat-covered hills further inland.
• •A sacred site for centuries, the mountain features the remains of an early Christian monastic settlement. Along the Pilgrim’s Path, walkers can still find the ruins of stone beehive huts and a holy well dedicated to Saint Hugh MacBracken.
• •The most famous approach involves crossing One Man's Pass. This narrow, rocky arête requires a steady head, as the ground drops away precipitously on one side toward the ocean and on the other to a mountain corrie.
• •From the trig point, the view extends far beyond Donegal. On a clear day, you can pick out the distinctive limestone plateau of Benbulbin in Sligo and the remote, jagged peaks of the Nephin Beg range in County Mayo.
• •While the 'One Man's Pass' implies a strict occupancy limit, the bottleneck is usually caused less by trail regulations and more by the sudden, quiet realization that the ground is a very long way down.
