Pollnagollum Cave and Waterfall

Pollnagollum Cave (meaning Hole of the Dove) is the longest cave system in Ireland. The cave system is complex and fascinating and is fed by a tumbling waterfall that topples off a limestone cliff. Watch your stepping here as rocks can be unstable and slippery, and don't forget your camera for some awesome shots.

Fairly accessible but not wheelchair accessible. Would be very careful with small children as well

"continual slur on Irish caving"
It's actually only a few hundred metres is accessible and it's total length is thought to be 2km. No where near the longest cave in Ireland.
Consider a trip in only if well equipped with a good light and helmet.
Alternatively/also consider visiting McKenzies back lounge just down the road. A much drier watering hole. ;)
