Predjama Castle and Postojna Cave sit within a few miles of each other in the Slovenian countryside, yet most visitors only make it to one. This small-group tour from Ljubljana covers both—starting with the 13th-century castle built into a cliffside cave, then descending underground at Postojna for a narrow-gauge train ride through the cave's vast chambers.

A Slovenian Karst classic awaits! Explore two of Slovenia's most stunning treasures: Postojna Cave, Europe’s most visited cave, and Predjama Castle, the world’s largest cave castle. Begin with Postojna Cave, a 24 km (15-mile) underground marvel featuring breathtaking stalactites, stalagmites, and a magical electric train ride through its winding passages. Spot the rare "human fish," a symbol of the cave's unique biodiversity. Just nearby, Predjama Castle rises dramatically from a sheer cliff face. This 13th-century fortress blends nature and history, with grand halls, secret tunnels, and legendary tales of knight Erasmus. Enjoy spectacular views and capture unforgettable moments of the surrounding landscape. Together, these iconic landmarks offer an adventure combining nature's wonders with Slovenia’s rich heritage. Flexible tours cater to your needs, promising an experience as memorable as the journey itself!
