The 18th EuroSpeleo Forum and the Meeting of Croatian Speleologists are two events joined into one, called “Mundus Spelaeus 2026”, both of which attract a great number of speleologists, friends of speleology, enthusiasts and nature lovers from across Croatia, Europe and beyond.

The aim of the event is to bring together researchers, scientists and enthusiasts to exchange experience and present the results of new research, to strengthen cooperation between European speleological federations and clubs, to share knowledge, standardize practices, and develop joint codes of ethics and technical standards for the exploration and protection of caves and pits.

This year, for the first time, Croatia is hosting the EuroSpeleo Forum – its 18th edition.
