Booking choice: The cave and castle tour with tickets, from $131 per person. Check dates Tour details
Postojna Cave Park sets its own prices and sells its own tickets. Nothing about that changes with the seasons, but the deals do: a combo with a crossed-out price, a family week at the end of October and a separate Christmas show in December.
Below are the figures on the official ticket page as of 14 October 2026, plus what each day tour from Ljubljana, Trieste, Koper and Zagreb actually covers.
The quick answer
An adult pays €34.90 for the cave, €24.00 for Predjama Castle and €49.90 for both on the Two Adventures ticket. From 24 October to 1 November 2026, two adults with up to two children under 15 pay €69.80 for the cave. Four tours on this site include both tickets; on the others you add the entrance on the day.
What do Postojna Cave tickets cost in 2026-27?
€34.90 for the cave and €24.00 for the castle per adult. Packages run from €39.90 to €59.90.
These are the adult prices the park shows today. Most packages carry a crossed-out price next to them, which is the sum of the single tickets. The park sells the cave ticket for a fixed tour time, so pick the slot when you pay. Every other sight in a package can be used any time within 30 days of your cave tour, per the ticket rules.
Our pick is the Two Adventures ticket. The castle adds €15 to the cave price, and it's the half of the day people remember.
| Ticket | What it covers | Adult price |
|---|---|---|
| Postojna Cave | Cave train and walk, about 1.5 hours | €34.90 |
| Predjama Castle | Castle, with the app tour | €24.00 |
| Two Adventures | Cave and castle | €49.90 (shown against €58.90) |
| Postojna Cave and Vivarium | Cave and the olm exhibition | €39.90 |
| Cave, castle and Vivarium | Three sights | €55.00 |
| Full Park Experience | Cave, castle, Vivarium and Expo | €59.90 |
How much is the Two Adventures ticket for students and children?
Students aged 16 to 25 pay €39.90, children from 6 to 15 pay €29.90 and children up to 5 pay €2.00.
The Two Adventures page lists four rates. Bring a student card: the discount is €10 against the adult price. The castle part comes with a guided tour on an app in 19 languages, and a rented audio guide at the castle desk costs €2.90 more.
A shuttle links the cave and the castle for combo holders in high season, a ride of up to 20 minutes. Out of season you need a car, a taxi booked at the ticket office, or a tour. The castle sits about 9 km from the cave.
Both tickets and the transfer in one booking, with pickup in central Ljubljana.
Check dates for the cave and castle tour with ticketsWhat is the family ticket offer from 24 October to 1 November 2026?
For those nine days, two paying adults bring up to two children under 15 for free. The cave alone costs €69.80 for the four of you.
The family ticket page applies the discount in the basket for the cave, and at step 4 of checkout for packages. The cave and castle family price is €99.80, against €159.60 at full rates. That's the best deal the park runs this autumn.
The cave tour ends with the olms, the pale cave salamanders the park calls baby dragons. Our guide to Postojna with kids covers strollers, the cold and the uphill stretch.
| Family ticket (2 adults + up to 2 children) | Full price | 24 Oct to 1 Nov 2026 |
|---|---|---|
| Postojna Cave | €111.20 | €69.80 |
| Cave and Predjama Castle | €159.60 | €99.80 |
| Cave and Vivarium | €127.60 | €79.80 |
| Cave, castle and Vivarium | €176.00 | €110.00 |
| Cave, castle, Vivarium and Expo | €191.60 | €119.80 |
Which day tours include the entrance tickets?
Four do: the flagship tour, the half day with all tickets, the Piran day and the trip from Trieste. The Koper port tour includes the cave only.
The listings look alike, which is the trap. Read the inclusions line before you compare prices.
- Both tickets included: the cave and castle tour with tickets ($131), the half day with all tickets ($121), the Piran day ($159) and the trip from Trieste ($143).
- Cave ticket only: the tour from Koper port ($113); the castle is a photo stop.
- Tickets extra: the small-group tour ($78), the hotel pickup tour ($80), the Bled day ($132) and the day from Zagreb ($135).
One thing no tour changes: inside the cave you follow the park's own guides or an audio guide, and at the castle you use the app. Your tour guide gets you there and back.
The most-reviewed way to do both: tickets paid, morning or afternoon pickup in central Ljubljana, audio guide at the castle.
Explore the cave and castle tour with tickets Tour detailsWhat does a tickets-extra tour cost once you add the entrance?
Add roughly €45 to €50 per adult to the tour price. That closes most of the gap with the tickets-included tours.
The operators quote their own figures for the combined entrance. The small-group tour's listing says from €45 with dynamic prices, the hotel pickup tour lists €44.50 with a 10% agency discount, the Bled day lists the cave and castle from €46.50, and the Zagreb day €41.90. The park's own Two Adventures price is €49.90.
On paper the small-group tour at $78 still wins on price. You also queue for tickets on the day, and the tour may be on a different cave slot than you'd pick. If that bothers you, pay the extra for the half day with all tickets.
| Tour | Tour price | Entrance the listing quotes | Tickets in the price? |
|---|---|---|---|
| Small-group tour | $78 | From €45 (dynamic) | No |
| Hotel pickup tour | $80 | €44.50, 10% agency discount | No |
| Bled, Postojna and Predjama | $132 | From €46.50 (optional) | No |
| Day from Zagreb | $135 | €41.90 | No |
| Half day, all tickets | $121 | Included | Yes, both |
| Cave and castle with tickets | $131 | Included | Yes, both |
