The Most Populated Irish Islands

Great Island is the most populous Irish island.

Ireland is an island located west of Great Britain and northwest of continental Europe, and is shared politically by the Republic of Ireland and Northern Ireland. Although Ireland is an island, the main island is often referred to as the mainland, since many smaller islands and islets are scattered around it and are part of Irish territory. The most populous islands of Ireland are listed below.

1. Great Island

Great Island of Ireland is located in Cork Harbor, close to Cork, a university city in Ireland. Great Island is Ireland's most populous island, and had a population of more than 13,000 in 2011. The island is famous for the tourist seaport town of Cobh that is located on the south side of the island.

2. Achill Island

Achill Island is the second most populated Irish island, with a population of 2,569 in 2011. The island is the largest Irish island in terms of size, with an area of 148 square km. The island is connected to the mainland by the Michael Davitt Bridge. The villages of Choire, Gob, Dooagh, Dooega, Keel, and Dooniver are some of the centers of population on the island. Achill Island has been inhabited by humans as early as 3000 BC, as evident by some of the artifacts found on the island. Achill parish hosts between 500 and 600 native speakers. Agriculture has never been a popular economic activity on the island, as the land does not support cultivation. Fishing was an important activity in the past, especially shark fishing. Currently, tourism is the mainstay of Achill Island's economy.
