The first stop, Postojna Cave, is a highlight with its spectacular interior formed over 2 million years. Known worldwide, it has welcomed 38 million visitors over its 200-year history. The underground world features a web of tunnels, galleries, halls, and passages, created by the Pivka River.
Visitors are treated to a fascinating underground train ride, which is a highlight of the visit. Inside, you’ll see stalactites, stalagmites, curtains, petrified waterfalls, and cave pearls. A unique creature, the “human fish” or proteus, also resides here—an eyeless, cave-adapted amphibian that adds a touch of intrigue.
Note that admission to the cave is not included in the tour price, with tickets costing €17 for the cave alone or €45.50 if combined with Predjama Castle. The 2-hour visit offers plenty of time to explore, but those with mobility considerations should be prepared for some walking and stairs.

Next, the tour visits Predjama Castle, a 1600s Renaissance fortress built into a 123-meter-high cliff. The castle’s dramatic position adds to its fantasy-like appearance and sense of mystery, especially considering its connection to underground cave systems.
The castle is the largest cave castle in the world and has been featured in the Guinness Book of Records. Inside, the museum displays objects uncovered during excavations, including chalices, goblets, a windmill cup, and candlesticks. The interior tour takes around 1 hour 30 minutes, offering insights into its architecture and history.
While admission is not included, the castle’s stunning exterior and mysterious history make it a captivating stop. Visitors should prepare for many steps within the castle and its cold interior, which adds to the atmospheric experience.

The final destination is the picturesque coastal town of Piran, known as the “Mediterranean treasure”. This authentic town boasts narrow streets, closely built houses, and spectacular views from the city walls. The main square features a statue of Giuseppe Tartini, a famed composer born here, and the St. George Parish church provides a charming backdrop.
Spending around 2 hours in Piran gives ample time to walk the streets, sit by the sea, and enjoy local seafood, like grilled sardines. The town’s Mediterranean spirit shines through with its coastal atmosphere and friendly vibe. Visitors are encouraged to explore independently, with plenty of picturesque spots to capture photos or relax.

While the tour price does not include entrance fees, it offers a flexible approach: you can choose to pay €45.50 for both Postojna Cave and Predjama Castle or opt for only one of the sites. This allows for customization based on interests and physical endurance.
