In the explored part of the cave there are several dozens of grottoes; the largest one, which is called the Druzhba (Friendship) Grotto, was given its name in honor of the participants of the International Geological Congress who visited the cave in 1937.
I den udforskede del er der dusinvis af separate grotter, hvoraf den største er Druzjba-grotten (dansk: ~ Venskabsgrotten), der fik navnet til ære for deltagere ved den Internationale Geologiske Kongres, som besøgte den i 1937.
