SUI was originally founded in the 1960’s and reconstituted in 1983. Today, the majority of Irish cavers are members of our organisation.

SUI provides training, supports conservation and exploration, and sponsors overseas expeditions. We also help to influence government policy on sport, access and the environment.

We also maintain very strong links with the Irish Cave Rescue Organisation (ICRO). Many SUI members also volunteer with ICRO.
