Pollnagollum, Cave system in the Burren, Ireland
The Pollnagollum cave system extends through 16 kilometers of limestone passages, making it the longest underground network in Ireland.
The initial exploration of Pollnagollum occurred in 1880 when T. J. Westropp ventured into the cave and reached the Main Junction.
The Burren region surrounding Pollnagollum contains three quarters of Irish plant species, including arctic-alpine plants and numerous orchid varieties.
Multiple entrances provide access to the cave system, with the main passage leading directly to an active underground stream network.
The cave passages include waterfalls formed where streams meet non-soluble chert beds, creating natural cascades within the underground system.
