Cnoc na Boirne [Murren Hill]

Rising above the rugged Fanad Peninsula, this prominent Donegal Marilyn offers a stony, heathery ascent typical of the Atlantic coast. Though modest in height, its coastal position provides a commanding perspective over the entrance to Lough Swilly, with the Urris Hills and Fanad Head Lighthouse defining the northern horizon.

• •The name Cnoc na Boirne translates from Irish Gaelic as "Hill of the Stony District," reflecting the rocky outcrops and thin soil characteristic of this corner of Donegal.
• •From the summit, walkers can look directly down upon the Atlantic coast near Doaghbeg, where the "Great Arch" stands as one of the most significant natural sea arches in Ireland.
• •The hill is a notable target for hill-baggers because its prominence makes it a Marilyn, a classification earned here by its topographical isolation from the higher mountains of the interior.
• •Navigating the lower slopes often involves a strategic negotiation with local gorse and historic stone walls, a reminder that in Fanad, the shortest route is rarely the easiest.
