At the edge of the world
They are among the highest sea cliffs in Europe, but it's difficult to imagine what that looks like, or how the sight will make you feel. It's not until you reach the top of Slieve League and stand near – but not too close! – to the edge, that the majesty of the 609m drop really begins to sweep over you.
It's not just the height, either; it's the panoramic views of Donegal Bay and the Sligo Mountains; the impossibly narrow One Man's Pass, which loops past the viewing point and around onto the Pilgrim's Path. It's the feeling you get when you stare at Mother Nature's canvas of sapphire blue sea and slay-grey cliffs and know you're witnessing perfection. It's no wonder National Geographic Traveller voted Donegal the coolest place on the planet.
If you have more time
Call into Glencolmcille Folk Village: the quaint, humble thatched cottages are exact replicas of the types of houses occupied by the people of Ireland in centuries past and give a valuable glimpse into a way of life now long gone.
