A geosite is a location that has a particular geological or geomorphological significance. As well as its inherent geological characteristics it may also have cultural or heritage significance. The geosites in the Burren and Cliffs of Moher Geopark were selected for their accessibility as well as their geological and cultural significance, to provide ease of access for visitors and educational groups. There are nine geosites in the Burren and Cliffs of Moher Geopark and they are described in detail in the book ‘Stone, Water & Ice - a geology trip through the Burren’ which is available at visitor centres and bookshops throughout north Clare.
Lisdoonvarna (Lios Dúin Bhearna, meaning the Fort of the Gap) is set within a landscape of steep shale hills, interspersed with the deep gorges of the Aille, Gowlaun and Kilmoon rivers. Where the upper shale layer meets the underlying limestone a number of mineral springs rich in sulphur, iron, magnesium and calcium emerge, providing Lisdoonvarna with the health-giving water that has attracted visitors to the town for over 150 years.
