Thanks to josephinemc for adding this peak.
It is the tallest peak of the Derryveagh Mountains, the tallest peak in County Donegal, and the 76th tallest peak in Ireland. Errigal is also the most southern, steepest and highest of the mountain chain, called the "Seven Sisters" by locals. . The nearest peak is Mackoght, which is also known as Little Errigal or Wee Errigal (Irish: an Earagail Bheag).
Errigal is well known for the pinkish glow of its quartzite in the setting sun. Another noted quality is the ever-changing shape of the mountain depending on what direction you view it from. Errigal was voted 'Ireland's Most Iconic Mountain' by Walking & Hiking Ireland in 2009
