Postojna Caves: Full-Day Bus Tour from Trieste

Visit the largest cavity in the classic Karst and one of the most beautiful nature shows in the world, the most visited tourist cave in Europe.
Hop onto an electric train into the karstic subsoil to gain insight into a fantastic world of caves, passages and large rooms, adorned with stalactites and stalagmites of the most varied shapes and shimmering colors that nature has created, drop by drop, over millions of years.
See the red hall, the white room, and the spaghetti room, where thousands of white stalactites descend from the ceiling. End your visit with the large concert hall, and experience the most unique acoustics in the world, which for special occasions may contain some thousands of people.
