The Postojna Cave: A Journey into Nature’s Underground Art

Postojna cave, Predjama castle and Lake bled from Ljubljana - The Postojna Cave: A Journey into Nature’s Underground Art

The tour begins with a visit to the Postojna Cave, which stretches 21 kilometers underground. Over millions of years, waters of the River Pivka have carved out this labyrinth of passages, caverns, and grand halls. Inside, the cave walls are decorated with dripstones, translucent curtains, and unique pillars that showcase natural artistry.

The 1 hour and 30 minutes spent here provide plenty of time to marvel at the formations, though the admission ticket is not included in the tour price. Visitors can expect a train ride that takes them into the cave, which is often mentioned as a particularly fun and memorable part of the experience. Because the cave maintains a constant temperature of 10°C (50°F), bringing warm and comfortable shoes is recommended.

Exploring Predjama Castle: A Fortress on a Cliff

Following the caves, the tour stops at Predjama Castle, a dramatic fortress perched over a 100-meter-high vertical cliff. This medieval castle has a long history filled with legends and myths, and its unique location makes it a striking photo opportunity.

In just 1 hour, visitors can walk around the castle, explore its rooms, and hear stories about its past. Like the cave, admission is not included and costs €45 per person. The castle’s dramatic setting and the stories associated with it make it a highlight for many travelers, especially those interested in history and architecture.

Scenic Beauty at Lake Bled: Paragliding into Paradise

The highlight of the trip is the 4 hours spent at Lake Bled, often called the “Image of Paradise.” This Alpine resort town is famous for its emerald-green lake, a tiny island with a church, and a castle perched atop a rocky cliff overlooking the water.

In warm weather, there’s an option to swim in the lake during free time—something that can be enjoyed in the summer months if the weather allows. Visitors can explore the lakeside, walk around, or take a Pletna boat ride to the island (additional €20 per person). The Bled castle is also worth a visit, with an entrance fee of €18, which includes a famous cream cake well-known locally.
