Postojnaka Jama has 24 kilometers of underground passages full of stalagmites and stalactites. We traveled about a kilometre and a half into the caves by a small, bright yellow train.
Some of the rocks are glossy and smooth, while others are sparkly with crystals and we passed through passages where we could have touched the ceiling easily, while other caves were bigger than two football fields put together!
We walked a few kilometers in the caves as we wound down to the lower level. Here we saw small pools of water and we learned that scientists are studying over 150 different species of creatures that live here. One creature is the "baby dragon" which is the Postojna Cave olm. People used to believe they would grow into real dragons, but they're an animal with no pigment at all in its skin. That makes it very sensitive to light and it's against the law to take any kind of picture of them.
After mailing ourselves a postcard from the underground post office located in the caves, we climbed aboard the train to head back up to the surface. The dwarves from Lord of the Rings would have felt right at home in these caves.
What an amazing tour!Read more
