The Burren (/ˈbʌrən/; Irish: Boireann, meaning "great rock") is a region of environmental interest primarily located in northwestern County Clare, Ireland, dominated by glaciated karst (or sometimes glaciokarst) landscape. It measures, depending on the definition, between 250 square kilometres (97 sq mi) and 560 square kilometres (220 sq mi). The name is most often applied to the area within the circle made by the villages of Tubber, Corofin, Kilfenora, Lisdoonvarna, and Ballyvaughan, and Kinvara in extreme south-western Galway, including the adjacent coastline.
