Explore Donegal South Donegal Southwest Donegal Central Donegal The Rosses Gweedore and Tory Island The Derryveagh Mountains and Glenveagh The north Donegal coast The Fanad Peninsula Letterkenny and around The Inishowen Peninsula Share Horn Head is magnificent, an almost two-hundred-metre rock face scored by ledges on which perch countless guillemots and gulls and small numbers of puffins. The best view of the cliffs, sea-stacks and caves is from the water, but the cliff road is vertiginous enough in places to give you a good look down the sheer sides. To get here take the slip road at the western end of DUNFANAGHY village; it descends to skirt the side of a beautiful inlet before rising steeply to go round the east side of the head. A spectacular vista of headlands opens up to the east – Rosguill, Fanad and Inishowen – but none can match the drama of Horn Head’s cliffs, their tops clad in a thin cover of purplish heather. Alternatively, you can walk from Horn Head Bridge, 800m from Dunfanaghy on the Horn Head road, and head west across the dunes to Tramore Beach. Then follow the sheep track north, passing two small blowholes called the Two Pistols and then a much larger one, McSwyney’s Gun, so called because of the power of the sonic boom produced by the explosion of compressed air from the cavern. Erosion has occurred over the years, however, and you’ll be lucky to hear anything these days. Continuing onwards, you’ll come to Pollaguill Bay and beach. The next wondrous site is the more than twenty-metre high Marble Arch, cut by the sea through the base of Trawbreaga Head. Horn Head itself soon becomes visible as you ascend the next headland. The walk as far as here takes around three hours from Dunfanaghy and you can either complete the whole circuit of the peninsula or head back by road.
