It spans approximately 2,300 meters, with a tourist-accessible section featuring distinct halls named after their unique formations. The cave system is divided into two primary levels, a dry fossil level and an active river level. It is named after a legendary local figure, Rajko, who was said to be a guardian of hidden gold. The cave is managed by the Tourism Organization of Majdanpek.
