The Easiest Cave Day Without a Car
If you want one “wow” day outside Ljubljana that doesn’t require a car, Postojna is a top choice. It’s visitor-friendly, weather-proof, and close enough that you can still be back for dinner by the Ljubljanica.
The secret is to keep logistics light: choose the simplest timetable (bus or train), do the cave as your main highlight, and treat any add-ons as optional.
Map: Station → Postojna → Cave
The trip is essentially two steps: Ljubljana → Postojna town (bus/train), then Postojna town → cave complex (local connection).
Step-by-Step: How to Do It
1) Choose bus or train by timetable fit
Pick the route that looks simplest for your day. If one option has awkward gaps or late returns, choose the other. Early starts make the whole day smoother.
2) From Postojna town to the cave complex
Once you arrive in Postojna, you’ll need a short “last mile” connection. Depending on season and local services, that can be a taxi, a local bus, or a walk. Check the official cave visitor info close to your travel date for the easiest current option.
3) Keep Predjama optional
Predjama Castle is an amazing add-on, but it’s only a good no-car add-on when connections are truly smooth. If it looks complicated, do Postojna as your full day and keep your return easy.
Best finish back in Ljubljana
After caves, the city feels cozy. Do dinner, then one slow bridge loop at night.
