Glencorrib is a small village located over limestone on the edge of Lough Corrib and at the southern edge of County Mayo. The local GAA club is run with nearby Shrule and the village also includes a church, a creche and a primary school. A number of turlough (from the Irish Turlach, “the dry place”) surrounds the village. These seasonal lakes are quite common in this part of the Geopark but in fact very rare internationally. They appear in natural depressions that have a central hole in the bedrock acting as a spring in the winter when the groundwater level rises and as a swallow hole in the summer.

One of the most famous site in Glencorrib is Ballycurrin Lighthouse, built in 1772 by Henry Lynch to get his provisions from Galway city to his home beside. It is meant to be a very rare example of a freshwater lighthouse in Europe.
