Unless one is an avid spelunker, one does not think of caves when one thinks of Ireland. However, the island is actually a location with a number of interesting geological features, including a number of caves that can be explored by a casual traveler. Generally, most of the caves in Ireland are known as “Show Caves”, which means they are operated by either a onsite concessionaire, or the government, and access is regulated via guided tours. While there are caves one can explore on one’s own, most notably in the Burren region, these caves are the purview of actual cavers, not casual tourists. Out of all of the caves in Ireland, there is only one cave that was the actual site of a mass murder, and that is Dunmore Cave.
