Dunmore Cave

Recommended stay: 1 day
Getting around: Dunmore Cave is about 10 minutes' drive north of Kilkenny city off the N78; there's no public transport directly to the site, so a car or taxi is needed. The cave is accessed via a guided walk with steps, not suitable for those with limited mobility.
Hours: Generally open daily with seasonal variation, typically shorter hours or partial closure in the depths of winter — check current opening times and guided tour schedules before visiting.

Dunmore Cave is a limestone show cave a short drive north of Kilkenny city, known for its impressive calcite formations — including some of the tallest stalagmites in Ireland — and for a darker chapter of history: archaeological evidence and later Viking-era annals suggest the cave was the site of a massacre of local people during a Viking raid in 928 AD, with human remains and Viking-era coins found within it.

A visitor centre explains the geology and history before a guided walk takes you down into the illuminated cave chambers, which stay a constant cool temperature year-round. It's a manageable, family-friendly outing rather than a strenuous adventure caving trip, and makes a good half-day combination with Kilkenny city or Kells Priory nearby.
