Inis Oírr is situated 17km off the Galway coast and 9km off the Clare coast. The beach is on the northern coast of the island and is known as Trá Inis Oírr. Traditional farm practices have helped maintain the high ecological status of the island. The birdlife of Inis Oírr is of international importance due to the presence of species listed under Annex 1 of the Birds Directive. Choughs breed on the island. Other protected birds on the island include Little Tern, Artic Tern and Sandwich Tern.
