Muckish

Muckish () is a distinctive flat-topped mountain in the Derryveagh Mountains of County Donegal, Ireland. At , it is the third-highest peak in the Derryveagh Mountains and the 163rd highest in Ireland. Muckish is also the most northern and second highest of the mountain chain called the "Seven Sisters" by locals. The Seven Sisters are Muckish, Crocknalaragagh, Aghla Beg, Ardloughnabrackbaddy, Aghla More, Mackoght, and Errigal.

==Overview== High-grade quartz sand was mined on the flanks of the mountain; the remains of the quarry workings can be seen on its northern side. The "Miner's Path" is a route to the summit up the northern side of the mountain. Part of this route follows the path used by the workers to reach the quarry. The sand was exported and was mainly used in the manufacture of optical glass. A less difficult route to the summit begins from the Muckish Gap on the southern side of the mountain.
