About Achillbeg Island

Achillbeg is a small island off the southern coast of Achill Island in County Mayo, Connacht. It was permanently inhabited until a mid-20th century relocation.

The island is compact and sparsely developed, with visible ruins of former cottages and simple stone field walls. People visiting typically come for short boat trips, coastal walking and sea-bird watching rather than facilities or services.

A small rural community lived on the island until residents were relocated in 1965. Since then it has been largely uninhabited and used only for seasonal visits.

Sitting off the southern shore of Achill Island in County Mayo, the island is reached by private boat or local charter from Achill during the summer months.

  • Access: Visits are by private boat or local summer charters; there are no regular public transport services.
  • Evacuation: The island’s last permanent residents left in 1965 during a government relocation programme.

What to See#

  • Abandoned village: Remains of the small seasonal settlement include stone cottages and low walls; there are no public facilities on the island.
