It is little wonder that Mount Errigal in Co Donegal was once voted the most iconic mountain in Ireland as it protrudes from the landscape like a volcano and glows a pinkish hue in the sun.

Standing 2,464 feet (751m) above Gweedore, Mount Errigal is the tallest peak of the Derrybeagh Mountains. It is also the most southern, steepest, and highest of the mountains named “The Seven Sisters” by the locals. The other Sisters are Muckish, Crocknalaragagh, Aghla Beg, Ardloughnabrackbaddy, Aghla More, and Mackoght.

The pinkish glow of the striking mountain is due to its quartzite rock reflecting the setting sun. In fact, as you get close up and personal with the volcanic-looking mass, you realize that what appeared to be snow on the mountaintop is actually the quartzite rock. No wonder it is one of the most popular spots for mountain climbing in Ireland.

The popular hiking path takes just one hour to climb to the peak along a trail leading from the main road. The walk heads 1.2 miles past the Poisoned Glen turn-off, up the southeast ridge. The short climb to the summit is worth it for the stupendous views – you can see all of Donegal and most of Ulster and even the Aran Islands, off Galway, from the peak. From the top, you could spend hours tracing the region’s coastlines, loughs, and mountains.

After reaching the summit you can then walk over to the second summit along a walkway dramatically titled “One Man’s Pass.”
