Why Postojna Works as a Day Trip
Postojna is one of those “slovenia is full of surprises” moments: huge underground spaces, dramatic formations, and a visit that feels like an adventure without demanding an all-day hike.
It’s also an excellent choice when weather isn’t perfect—pair the cave with one more highlight (Predjama Castle) and you have a full, satisfying day.
Map: Postojna + Predjama Combo
This is the classic combo day: cave first, castle second, then back to Ljubljana for dinner.
A Simple Postojna Day Plan
Morning: Cave First
- • Start early for easier logistics
- • Do the main cave visit, then take a short break
Midday: Add Predjama (Optional but Excellent)
Predjama Castle gives you the perfect contrast: a castle built into a cliff, dramatic and cinematic in a completely different way than the cave.
Evening: Back to Ljubljana
Finish your day the Ljubljana way: dinner by the river and a slow night walk across the bridges.

Postojna Cave Day Trip FAQs
Is Postojna Cave worth visiting from Ljubljana?
Yes—Postojna is one of the most famous caves in Europe and a very accessible “wow” day trip. It’s a great choice if you want dramatic nature without a long hike.
Should you do Postojna or Škocjan?
Both are excellent. Postojna is extremely visitor-friendly and famous worldwide; Škocjan is more dramatic and UNESCO-listed. Choose the vibe you want and the schedule that fits your day.

Yes—this is one of the best day-trip combos near Ljubljana: underground landscapes plus a cinematic cliffside castle.
Is Postojna a good rainy-day trip?
