Postojna Cave and Castle with Ljubljana starts from Maribor

Step into one of the most spectacular caves on Earth. Postojna Cave is a breathtaking underground kingdom of towering stalactites, vast halls, and mysterious passages — a natural wonder that has amazed visitors for over 200 years.

Stretching over 24 kilometers, Postojna Cave is one of the largest and most visited show caves in Europe. Its extraordinary formations were shaped by nature over millions of years, creating a surreal landscape that feels almost otherworldly.

Your adventure begins with a ride on the world’s only cave railway, taking you deep into the heart of the cave before continuing on foot through its most impressive chambers.

Rising dramatically from a sheer limestone cliff, Predjama Castle is one of the most extraordinary castles in Europe. Built directly into the mouth of a cave, it looks like something out of a legend — and its history truly lives up to the scene.

Predjama is the largest cave castle in the world, seamlessly blending human architecture with raw nature. Hidden tunnels, secret passages, and chambers carved into the rock tell stories of sieges, rebellion, and clever survival.

The castle is famously linked to Erazem of Predjama, a rebellious knight often compared to a Robin Hood figure. During a year-long siege, he outsmarted his enemies using a secret cave passage to bring in food — until betrayal finally sealed his fate.
