When visiting Slovenia, be sure to see Postojna and Predjama Caves. Postojna Cave is the most visited cave in Europe, known for its unique underground creatures, the baby dragons – human fish or proteus, which can live up to 100 years. You can explore the cave’s wonders, including a Christmas show, by taking a train ride on the 140-year-old railway that runs through the cave.
Near Postojna Cave, you can find Predjama Castle, the largest cave castle in the world. For over 800 years, it has been guarding a 123-meter-high rock face and is connected to a mysterious underground cave through tunnels.
