Blue Stack Mountains

The Blue Stack Mountains[1] or Bluestack Mountains, also called the Croaghgorms (Irish: na Cruacha Gorma, meaning "the blue stacks"), are the major mountain range in the south of County Donegal, Ireland. They provide a barrier between the south of the county, such as Donegal Town and Ballyshannon, and the towns to the north and west such as Dungloe and Letterkenny. The road between the two parts of the county goes through the Barnesmore Gap.
