Total cave length (for caves of 1 km and above): 110.268 km.

If you don't see the cave you want, but you know it should be in the RO Ireland section, remember that this list only shows caves with at least 1 km length of natural passage. Other caves may show up in the list of deepest caves in RO Ireland.

However, if you are looking for a specific cave that does have at least 1 km length of natural passage, and should be listed here, please let me know about it so I can update the database.
