Flights & getting there
Major towns in Donegal are served by buses that link to both Dublin and Northern Ireland. There is no train service. Scenic Donegal Airport is little used. It has twice-daily Aer Lingus flights to Dublin, that's primarily for connecting to other flights, and five flights a week to Glasgow International Airport. It's about 3km northwest of Annagry on the northwestern coast. In 2017 it was voted the world's second most scenic airport.
Bus Éireann Serves mostly the southwestern part of the county. Main routes include Sligo–Bundoran–Donegal Town–Letterkenny–Derry, Donegal Town–Killybegs–Ardara–Glenties–Dungloe and Killybegs–Kilcar–Glencolumbcille.
Bus Feda Serves the northwestern part of the county, with a looping route from Galway and Sligo to Bundoran, Donegal Town, Letterkenny, Dunfanaghy and Gweedore, terminating in Crolly.
