Árainn Mhór is situated in a Gaeltacht (Irish speaking area) in the Republic of Ireland, approximately three miles from the Donegal mainland.

The island is serviced throughout the year from the fishing village of Burtonport by regular ferries. The journey from Burtonport on the mainland, to the pier in Leabgarrow takes you between a number of small islands, before crossing the stretch of open Atlantic known as Aran Roads.

The narrow channel between Rutland island (Inis Mhic an Doirn) and Inishcoo (Inis Cú/Ederinish island is known as The Black Hole due to its deep, dark, fast moving waters. The shelter provided by the islands allows the Ferry to run in all but the most severe weather conditions.

The proximity of Carrickfinn International Airport (25 minutes by car to Burtonport pier) and the accessibility provided by bus from Galway/Dublin/Belfast make Árainn Mhór an ideal destination for weekend and short breaks.
