Who are we? What do we do?


Clean underground is a volunteer-based speleological initiative that fights waste disposal in the karst underground. Over 900 polluted caves and pits threaten our unique cave fauna and potable water supplies! Since 2015, Clean underground organizes and finances waste cleanup campaigns in speleological objects and gives talks on the importance of karst preservation. Our work has been recognized locally and internationally so we influence state institutions to improve the legislative on karst protection in Croatia.
