Knockalla [Cnoc Colbha]

Forming a dramatic ridge along the Fanad Peninsula, this Marilyn overlooks the deep waters of Lough Swilly. Known locally as the Devil’s Backbone, its rugged heathery crest offers superb views across the bay to the Urris Hills and the golden sands of Ballymastocker Bay far below.

• •The Irish name Cnoc Colbha translates to 'Hill of the Ledge' or 'Hill of the Brink', an apt description for a ridge that drops steeply toward the sea on its eastern flank.
• •From the summit, the view northeast overlooks the vast arc of Ballymastocker Bay, which was once famously ranked by The Observer as the second most beautiful beach in the world.
• •Across the mouth of Lough Swilly, walkers can clearly identify the rugged peaks of the Inishowen Peninsula, most notably the high, rounded mass of Slieve Snaght.
• •The steep lower slopes of the ridge are home to the Knockalla Hillclimb, a legendary stage of the Donegal International Rally known for its narrow, hair-raising bends.
• •While its height is modest, the ridge’s 'Devil’s Backbone' nickname suggests the terrain is significantly less forgiving on the ankles than a gentle stroll along the nearby Portsalon sands.
