Running the Cliffs of Moher path will make for a memorable running experience. The Cliffs of Moher tower over the rugged west Clare coast and feature a series of pathways atop the cliffs, with spectacular vistas over the Atlantic Ocean and the Aran Islands. Among the thousands of miles of clifftop paths in Ireland, this one is among the most runnable: good surface, and not too hilly! The combination paved and gravel path runs for nearly 7 miles, from near Doonagore Castle in the north to the Moher Tower at Hag’s Head in the south. The surface is good and there are great views the whole way. There’s really only one major hill — at the northern end, a 440-foot rise between miles 1 and 3, average grade 3.8% — and a couple of narrow sections. Major sites are O’Brien’s Tower and Hag’s Head.
A good option is to start at the Visitor Center (parking, facilities), and run south for 5 km to Hag’s Head, making for a relatively flat, nearly 6 mile out and back run on a good surface. From the Visitor Center north to Doolin is 8 km.
Note: the area is open and exposed — can be windy & wet!
