The largest cavern had a 300 m arched roof with a mountain in the middle to wind around and then a bridge made by Russian prisoners of war over the dry river bed into a substantial passage way through many, many formations. The river does go through 3 other levels and most of the cave is wet and actively growing - dated for the last 500,000 years. An hour later we found ourselves in the final cavern of the tour, 50 x 80 m, and then back to the train and lunch.
Now back at the water - although this far North in Opatija, the forest does meet the sea so it is not so dry and rocky, bit more Italian perhaps.
See you soon
Love Wendy and Graeme
What a wonderful experience! I think I could almost explore caves such as these, particularly the little train trip.....and then back to the water, lovely day, thanks for sharing it xox
