It's a seldom-visited area of County Mayo, yet it boasts some of the most impressive coastal clifftop scenery in the entire country. After spending five years covering and exploring the landscape of the entire country, Robert Lloyd Praeger in his seminal book, The Way That I Went (1937) noted the spectacular nature of the landscape. Thousands of years of Atlantic erosion have created a series of sea stacks, sea arches and vertical cliff drops all haphazardly combining to create a breathtaking coastal landscape.
It's surprisingly well marked out, watch out for the Purple Arrows leading the way. If you wish to see the most dramatic parts you will have to veer slightly away from the main trail. There is a low-lying sheep fence running up the length of Benwee Head. The fence ends near summit area of Benwee Head overlooking Kid Island on your left. On a clear day, you can see both Sliabh Liag and Croaghaun in the far distance. The second highest and highest sea cliffs in Ireland. The trail heads back inland, but personally, I wouldn't do this. Turn right around and head back in the same direction to see this astounding scenery for the second time. It's not a difficult trek but do allow about 3-4 hours in total.

Make sure you go all the way out to the "EIRE" sign embedded into the ground, (the views here are staggering). The sign, a leftover from WW2 signifying Ireland's neutrality to air bombers overhead, both Allied and German.
