About

Quick facts: Over 24,000 meters of passages stretch underground, making it one of the largest karst cave systems in the world. The cave hosts the unique olm, a blind salamander that lives exclusively in this subterranean habitat.

Highlights: The cave tour features an electric train journey through the dark corridors, adding an exciting twist to the underground adventure. Stunning stalactites and stalagmites form intricate shapes, creating an otherworldly landscape that feels like stepping into a fantasy realm.

Insider tips

  • Wear sturdy shoes as paths can be slippery and uneven.
  • Bring a light jacket because temperatures stay cool year-round.
  • Capture photos during the wide chambers where light is better and tripods are allowed.
  • Book tickets early to avoid long lines on weekends and holidays.
