6. Cave Modrič
Head into a cave that is still intact by human comforts, and completely authentic. Modrič Cave, discovered in 1980s and closed off to the public until 2004, is an atypical attraction today, as there are no steps, paths, or lighting inside. Forget about fashion here, you will put on overalls and a helmet with a carbide lamp for this truly unique experience. Dressed for the occasion, and fully equipped, explore the halls, corridors and gaps of the 840 meter long cave filled with cave decorations, stalactites and stalagmites!
