Postojna Cave & Predjama Castle Day Trip from Sistiana

Summary

Guided Sistiana Tour: Postojna Cave Train Ride & Medieval Castle Visit

You’ll ride an underground train through Postojna Cave’s vast tunnels, spot rare proteus salamanders, then step into history at cliffside Predjama Castle—all with local stories and easy access from Sistiana.

What’s the experience like?

The drive out from Sistiana was quiet, just the hum of the van and a bit of morning mist hanging over the fields. Our guide, Luka, kept things lively with stories about Slovenia’s karst landscape—he even pointed out a bakery in Sežana where he grabs his favorite potica when he’s passing through. By the time we reached Postojna Cave, I’d already learned more about caves than I ever expected.

Stepping inside, you feel that sudden drop in temperature—10°C all year round. Glad I brought my jacket. The electric train is a bit of a thrill; it rattles along through these huge chambers, and you catch glimpses of weird rock shapes flashing by. Luka nudged us to look for the “Brilliant” stalagmite—it really does shine under the lights. We walked deeper into the tunnels, and at one point, everything went quiet except for water dripping somewhere far off. The highlight? Seeing the proteus up close in its tank—those little pale creatures are stranger than any fish I’ve seen.

After warming up with coffee at the cave café (the barista joked about tourists always underdressing), we headed to Predjama Castle. It’s perched halfway up this cliff—honestly looks like something out of a movie. Inside, you can almost feel how cold and tough life must’ve been centuries ago. There’s a draft in every room and echoes bounce off stone walls. Luka told us about Erazem, the local legend who held out here during a siege; apparently there’s still debate in town about how he managed it for so long. The Lokva River disappears right under the castle—you can hear it if you stand quietly near the back entrance.
