About Arranmore

Arranmore (Árainn Mhór) is an inhabited island off the northwest coast of County Donegal in Ireland, known for its maritime community and Gaelic-speaking heritage. It is one of the larger inhabited islands off Ireland’s west coast.

The island offers coastal walks, sea cliffs, and local cultural life concentrated in small settlements; wildlife viewing and boat trips around the island are common activities. Services and small shops are concentrated in the main village and ferry terminal.

Historically a fishing and farming community, Arranmore has long retained a distinct island culture and continued use of Irish; its population and economy have fluctuated with changes in fishing and tourism. Modern infrastructure includes a regular ferry link to the mainland.

Located off the coast of County Donegal, Arranmore lies west of the mainland town of Burtonport and is reached by a short ferry crossing from the Donegal coast.

  • Gaeltacht island: One of Ireland’s Gaeltacht islands where Irish (Gaeilge) is still spoken by a portion of the community, offering a living linguistic and cultural experience.
  • Ferry terminal: Main ferry services land at the island’s principal village, Leabgarrow, which is the island’s primary port and settlement.

Getting There & Around

How to Get to Arranmore

Arranmore (Árainn Mhór) is reached by ferry from Burtonport on County Donegal’s coast. Drive to Burtonport (the port village) and take the vehicle/passenger ferry to Arranmore - ferries are the regular link for locals and visitors.

From Letterkenny the drive to Burtonport is roughly 35-40 km west (about 40-50 minutes) via the N56; check the sailings in advance as schedules vary seasonally and during bad weather.

Tips for Visiting Arranmore

  • Take the ferry from Burtonport and check the ferry timetable in advance - sailings are limited and subject to weather, especially outside summer months.
  • Once on Arranmore, follow the island's loop road away from the main harbour village to reach quieter beaches and scenic viewpoints that many day-trippers miss.
  • If you plan to bring a vehicle, reserve a vehicle space on the ferry in high season; otherwise travel light and consider hiring a bike on the island to cover more ground.
