The Donegal Gaeltacht in County Donegal comprises of a number of town lands and areas the heart of which can be found near the mystic mountains of the Derryveagh range and the scenic Poisoned Glen.

In the southern part Cill Chartha (Kilcar), Gleann Colm Cille, and Ard a'Ratha (Ardara) are home to craft workshops producing hand-woven Donegal Tweed. Moving north along the craggy coastline and somewhat inland, one comes to Donegal's Gaeltacht Lar (central Gaeltacht), located between Gweebara Bay, Gleann Fhinne, and Glendowen. Head further north and you enter the Rosses, Gaoth Dobhair and Cloich Cheann Fhaola, areas of haunting natural beauty. The most northerly point of the Donegal Gaeltacht is located via the Rosguill Peninsula with journey's end at Fanad Head.
