Inis Mór

Inis Mór is the largest of the Aran Islands in Galway Bay, Ireland. The island stretches 12 kilometers in length and rises to 123 meters above sea level at its highest point.

During the Cromwellian conquest in 1653, the island served as a prison for Roman Catholic priests. The detained clergy were released in 1662.

Residents continue to speak Irish Gaelic as their main language in everyday conversation. Many locals switch between Irish and English depending on whom they are talking to.

Ferries run regularly from Rossaveal and Doolin ports to the island, taking around 40 minutes across Galway Bay. Visitors can explore on foot or by bicycle, following small roads and paths along the coastline and through the interior.

The limestone surface displays a pattern of deep cracks called grikes, separating individual blocks of rock from one another. These formations developed 330 million years ago beneath a tropical sea.
