Muckish
Mountain Quartzite mountain in Donegal with flat-topped ridge
Flat-topped quartzite mountain in County Donegal, Muckish draws hikers for a steep ascent, ridge walking and wide views over Inishowen and Lough Swilly on clear days.
Muckish is a prominent flat-topped mountain in north County Donegal, Ireland, with a summit around 666 metres above sea level. Its distinctive plateau and quartzite composition make it a local landmark.
