Slieve League, at 601 metres has some of the highest sea cliffs in the country. Slieve League's cliffs reach almost three times higher than the cliffs of Moher in Co. Clare. With a steep drop off on its northern side, its southern face drops right into the Atlantic from the long knife-edge which forms the summit. This ridge, the "One Man's Path", is one of the most remarkable walks to be found in Ireland.
