Lisdoonvarna Spa Wells is a site of Geological importance and as a result have been designated a Geopark Geosite. Lisdoonvarna is best known for its Spa Centre and its festivals.
The town of Lisdoonvarna is built on a geological unit known as the Clare Shales, which lie directly on top of the limestone that comprises most of the Burren. The limestone is exposed in the beds of the rivers which flow through the town. For over 300 years, the waters that flow from springs in the Clare Shale in Lisdoonvarna have attracted visitors for their curative properties. The waters are rich in sulphur and iron and in 1875 the first bath-house was built.
The Victorian Spa Wells became famous for their therapeutic mineral waters and by 1895 over 20,000 visitors were visiting annually. The spa itself has been closed since 2014. The Victorian Pump house has been restored and is open daily with an exhibition on the history of the wells over the past 300 years. Visitors to the pump house can view the sulfur well which is illuminated and can taste the water. Full details of the experience are available in the Lisdoonvarna Failte Tourist office on main street Lisdoonvarna.
