Stunning huge cave of great beauty. You will get there by 2km train track and will be guided around the pathway. In the end of the tour you also get to see underground river. Amazing experience!
Feel like in a fantastic world. Totally amazing experience, will never forget. Must see this incredible cave&human fish. Entrance fee was 27 Eur, tour takes around 1,5-2 hr. Get your coat, cold inside
Wow like wow. Epic cave must visit. For families with kids bring foldable strollers. The aquarium was good also. Last tour at 4pm. The guide might treat you to a song.
Highlight for us was at the end of the tour when there a surprise performance by a saxophonist playing wondrous Christmas tunes. In a world full of divine limestone sculptures, music sounded magical.
The cave is amazing, a bit expensive but still worth the money. Make sure you have some warm clothes. Avoid restaurants around, nothing special and way overpriced.
Se você comprou a entrada na estação de ônibus de Ljubljana, por exemplo, você tem que trocá-la pelo ingresso quando chegar #ficadika a caverna é linda e a visita vale a pena (:
