A Closer Look at the Tour Itinerary

Starting Point at KoperTours

The adventure begins at the designated meeting spot, conveniently marked by an orange banner with the Hop & Taste logo near the passenger pier in Koper. Arriving 15 minutes early is recommended to settle in and meet your guide. The actual group sizes are not specified, but reviews hint at a well-managed, comfortable experience with a friendly guide named Luca, who is praised for his knowledge and enthusiasm.

Transport to Postojna Cave

The bus ride from Koper to the caves takes approximately one hour. During this time, you’ll enjoy scenic views of Slovenia’s karst landscape, making the journey as picturesque as the destinations themselves. The vehicle is air-conditioned, which is a plus on warm days, ensuring your comfort as you chat with fellow travelers or relax before the cave exploration.

Guided Tour of Postojna Cave

The highlight of the day, a two-hour guided tour of Postojna Cave, immerses you in a subterranean world of stalactites, stalagmites, and astonishing rock formations. The cave system stretches over 20 kilometers, but only a portion is accessible to visitors. The tour includes a ride on an electric train—an efficient way to cover significant ground without fatigue.

The cave is renowned for its stunning formations and the chance to spot baby olms (Cave Dragons)—a rare, endangered species found only in a few sites worldwide. We loved how the guide explained these creatures’ delicate existence and their habitat. The temperature in the cave hovers around 13°C (55°F) even in summer, so bringing a warm layer is advised.

Review insights reveal that guides like Luca are appreciated for their passion and insight, making the cave’s natural history come alive. One traveler noted, “The caves were very impressive and interesting,” but also mentioned that the tour ran a little longer than expected, which can matter if you’re on a tight schedule.

Short Break before Predjama Castle

Predjama Castle Photo Stop

The castle is an absolute highlight—clinging dramatically to the cliff face, it’s the largest cave castle in the world. This spot offers incredible photo opportunities, with the castle seemingly suspended between sky and earth. The 45-minute stop allows for plenty of pictures and a quick walk around the exterior, but no interior tour is included in this package, which is important to note if you’re eager to explore inside.

One reviewer described Predjama as “a truly unique sight,” emphasizing how its position over the cave makes it an awe-inspiring monument and a fantastic backdrop for photos.
