The Pivka river has been carving the Postojna Cave for 2 million years. The water level has changed over time and created a beautiful "multi-level" underground world filled with stalactites, stalagmites, columns, curtains and other gorgeous shapes was gradually created as the water was leaving layers of limestone behind. The first visitors supposedly came to the cave as early as the 13th century, but the most beautiful parts of the cave were discovered in 1818. You’ll enter the cave by train. The train ride takes about 10 minutes, and then you’ll continue on foot with a guided tour. Stroll under the needle-thin transparent tubes hanging from the ceiling in Hall of Tubes. From under the Russian Bridge you will reach The Concert Hall from where you can see the amazing white Brilliant – a truly breathtaking sight. Despite dark, around 100 animal species live in the cave! The main attraction is, of course, the proteus, which was at first mistaken for a baby dragon.

Before visit, take a break on the terrace of the country inn in front of the defiant, mysterious Predjama Castle built in a rock and enjoy its stunning views. The castle is built as an impregnable redoubt, placed in the gaping mouth of a cavern halfway up a 123 m cliff. The castle holds great features – holes in the ceiling of the entrance tower for pouring boiling oil on intruders, deep and dank dungeons, and an eerie hiding place at the top called Erazem's Nook. After a nice half day experience we will return back to Ljubljana. Drop off will be at same location as pick up.
