Check availability→ Two questions
How long a day, and tickets in or out?
Seen the thirteen above and still torn? Every one of them puts you on the underground train and walks you through the same cave, so the choice is not the cave but the day around it. Pick the one that sounds like your day.
See it before you pay for it
The train, the chambers, and the castle in the cliff
Postojna is the cave you ride into: an electric train runs from the entrance through the karst passages and sets you down in the chambers, where the walking part begins among stalactites and stalagmites. Then the road climbs to Predjama, a castle built into the mouth of a cave in a cliff face.
Side by side
Five hours, or eleven with Bled or Piran
People book these interchangeably and then find out they bought different days. The short version is the cave and the castle and nothing else: five to six hours, back in Ljubljana by mid-afternoon. The long version keeps the same cave and adds Lake Bled or Piran on the Adriatic, ten to eleven and a half hours.

Verdict
Take the trip with tickets already in it
It is the one that leaves nothing to buy at the gate: six hours from Ljubljana with pickup in the city, a driver-guide, entry to both Postojna Cave and Predjama Castle and an audio guide at the castle. Rated 4.8 across 2,655 reviews; the next listing has 852.
Check dates and availability→Before you book
A train takes you into this cave
A railway runs from the entrance of Postojna Cave into the rock and carries you through the first galleries, so the visit begins well inside the hill rather than at the door. After that the day asks an hour or so on foot on a made path. The real decision is how long you want the day to be, and whether the entry tickets are already in the fare.
Two-minute check
Which trip fits your day?
Three things decide it: how many hours you can give the day, whether you want cave and castle admission settled in the fare, and how you like to travel. Answer three questions and find out before you pay.
How much of the day can you give it?The cave and castle fill half a day; Bled or Piran make it long
How do you feel about the walk underground?The train carries you in; the rest is on foot along a made path
What do you want in the day besides the cave?Every trip rides the underground train, so this is the part that differs
Answer the three questions above
You’ll get the trip that fits the day you described, and the one thing on its listing that would catch you out.

What it really costs
What a Postojna Cave day trip costs
Prices are per person and cover the return drive from Ljubljana, the driver-guide and the day itself. Where the listing says tickets included, admission to the cave and the castle is already in the number; where it does not, you get a discount at the gate.

Costs the listing doesn't show you
- The entry tickets, on most fares. Nine of the thirteen trips cover the transport and the guide and arrange a discount at the gate, so the ticket is still to pay.
- The rest of the day. Five hours on a listing is five hours out of your day in Ljubljana, and the long trips take ten to eleven and a half.
- The layer you did not pack. The air underground stays cool all year, and the change is sharpest on a summer afternoon.
- What you buy on the day. The fares cover the journey and what the listing names; the boat on Lake Bled, lunch and the shop at the cave are yours.
What is genuinely included
- The return journey from Ljubljana, air-conditioned on most listings
- The ride on the underground train into Postojna Cave, on every trip here
- A driver-guide on the road, and an audio guide at Predjama on several listings
- Entry to the cave and the castle on four of the thirteen listings
- Pickup from a central meeting point inside Ljubljana
- Free cancellation, with a full refund
The honest answer
Is a Postojna Cave day trip worth it?
Postojna is one of the very few caves anywhere that you enter by train: the electric railway runs from the entrance and puts you down among the chambers, so people who would never face a long climb underground come out of it grinning. Predjama is the largest cave castle in the world, wedged into a cliff.
What makes it worth it
- An underground train carries you into the cave, so the visit starts well inside the rock
- Predjama Castle is built into the mouth of a cave in a cliff
- It is cool underground whatever the weather above, in July as much as in January
- Four listings carry entry to the cave and the castle in the fare
- Free cancellation on the listings here, so holding a date early is low risk
Keep in mind
- The train ride is the start; the rest of the cave is walked on a made path
- Bring a layer: the air underground stays cool all year
- Adding Lake Bled or Piran turns a half day into ten hours or more
- Some fares give a discount on the tickets rather than including them
- Predjama Castle is a climb through restored rooms and passages in the rock
The trip, hour by hour
Ljubljana to the cave and back
Pick the length of the day, then the trip
Five or six hours covers Postojna Cave and Predjama Castle and gets you back for the evening in Ljubljana. Ten to eleven and a half adds Lake Bled or Piran. Free cancellation runs on the listings here.
Pickup in Ljubljana
Most listings collect from a central meeting point or from designated spots inside the city, and the drive out to Postojna is the first part of the day.
The queue, and who has already paid
Four of the thirteen trips carry entry to the cave and the castle in the fare, and several advertise a skip-the-line service. The rest buy tickets at the door, usually at a discount arranged by the operator.
The train takes you in
This is the part people come for: a railway that runs into the cave and carries you through the galleries before you get out and walk.
The halls, the formations and the olm
Stalactites, stalagmites and the chambers between them, walked on a made path, with the vivarium where the blind cave salamander lives at the end of it.
Predjama Castle under the cliff
A castle built into the mouth of a cave in a rock face, with restored living rooms, dungeons and passages behind them. Several listings include an audio guide for it.
Back in Ljubljana
Five to six hours if the day was the cave and the castle, ten to eleven and a half if Lake Bled or Piran went into it.
Best time of day
Take the earliest departure you are offered
The cave does not have a good hour and a bad one — it is the same temperature and the same light at nine in the morning as at four in the afternoon. What changes is everything around it. Cave entry runs to timed slots, and the early ones go into the quietest part of the day. An early start also leaves Predjama Castle with daylight on it, and on the long days with Lake Bled or Piran it is the difference between reaching the second stop in the afternoon and reaching it at dusk.
Underground
What the fare actually puts in front of you
The train in
A railway runs into the cave, which is why the visit starts deep inside the rock.
The formations
Stalactites, stalagmites and the halls between them, walked on a made path.
The castle in the cliff
Predjama sits in the mouth of a cave, and most trips pair it with Postojna.
The scale of it
The chambers are the reason the train exists — the cave is too big to walk end to end.
What it's like
One cave, one castle, and thirteen ways to spend the day
Postojna is the cave with a train in it. A railway runs from the entrance into the rock and carries you through the first galleries before you get out and walk, so the visit starts well inside the hill. That is why the drive out of Ljubljana, about an hour each way, is worth doing as a day rather than a detour.
Thirteen trips are bookable here and every one of them leaves from Ljubljana. Every one of them also pairs the cave with Predjama Castle — a castle built into the mouth of a cave in a cliff, half an hour further on. The two sit together on every listing because they sit together on the map.
The first decision is how long the day is. Five to six hours covers the cave and the castle and puts you back in Ljubljana for the evening; fares for that run from $57 to $131. Ten to eleven and a half hours adds Lake Bled or Piran, and most of the extra time is road.
The second decision is whether the entry tickets are in the fare. Four listings include entry to Postojna Cave and Predjama Castle; the rest cover the transport and the guide and arrange a discount at the door. Both are honest ways to sell the day, but they are not the same number, and the cheaper headline is not always the cheaper morning.
Our pick is the tickets-and-tour trip at $131. It carries 2,655 reviews at 4.8, where the next listing has 852, and the fare covers pickup inside Ljubljana, a driver-guide, entry to both the cave and the castle, a skip-the-line service and an audio guide at Predjama. Six hours, and nothing left to buy at the gate.
If the day has to be shorter or lighter, the small-group trips do the same two sights in five to five and a half hours in a minivan capped at eight people, from $78. You buy the tickets at the door, usually at a discount the operator has arranged, and you walk the cave with the group you drove out with.
The long days are a different proposition. Lake Bled and the cave in one go runs eleven and a half hours at $194, with entry to Postojna, Predjama and Bled Castle included and a cream cake by the lake. Piran and the cave runs ten hours at $113, with a stop on the city walls above the Adriatic.
Whatever you book, take a layer. The air inside the cave stays cool right through the year, whatever it is doing above ground, and the walk after the train is an hour or so at a group pace. Fares on this page run from $57 to $194, and free cancellation runs on the listings here.
If you have the whole day
The trips that add Lake Bled or the Adriatic
The cave and Predjama Castle fill half a day, and Slovenia is small enough that the rest of it can hold something else. Two of these add Lake Bled in the Julian Alps; the third runs on to Piran on the coast.

Plan the day
Five things decide how it goes: how many hours you want to be away, whether admission is in the fare, minivan or coach, what you wear for a cave that stays cool in August, and how early you hold the date.
Tickets and tour, six hours
Our top pick: entry to the cave and the castle in the fare, 2,655 reviews at 4.8.
The small-group minivan
Five hours, eight passengers, central Ljubljana pickup, from $78.
Cave and castle in half a day
Five and a half hours with a licensed driver-guide and a discount on both tickets.
The guided trip with audio
Six hours with a multilingual audio guide and the vivarium at the end of the walk.
Lake Bled added on
Eleven and a half hours, entry to Postojna, Predjama and Bled Castle included.
Piran and the coast added on
Ten hours, with a scenic stop on the Piran city walls above the Adriatic.
A layer for underground
The cave stays cool all year, whatever the weather in Ljubljana that morning.
Shoes you can walk an hour in
After the train you are on foot on a made path, at the pace of the group.
Something with a hood
Cave walls drip; the path is damp in places and so is the air.
Trousers rather than shorts in summer
Stepping out of a Slovenian July into cave air is a bigger change than it sounds.
Shoes with grip for Predjama
The castle is passages and stairs cut into rock, not a level floor.
A small bag only
You are in and out of a train carriage and along narrow walkways all morning.
Check whether the tickets are included
Four listings cover entry to the cave and the castle; the rest give a discount at the door.
Decide the length before the price
Five hours and eleven and a half hours are different days, not different fares for the same one.
Small group or coach
Several trips run minivans capped at eight passengers, which changes the pace of the whole morning.
Free cancellation on the listings here
Holding a date early is low risk, and the timed slots on the popular trips go first.
Book ahead for the slot, not a discount
Cave entry runs to timed slots. What booking early buys is the hour you actually wanted.
The cave runs all year
Departures run in every month, so the season changes the drive rather than the cave.
Postojna is about an hour from Ljubljana
Close enough that the cave and the castle fit inside half a day with time to spare.
Most listings pick up in the city
Either a central meeting point or designated spots inside Ljubljana; the listing says which.
Predjama is half an hour past the cave
Which is why the two are sold together on every one of the thirteen trips here.
Lake Bled is the other direction
Adding it means crossing back past Ljubljana, and that is where the extra hours go.
Piran is on the coast
An hour and a half beyond Postojna, which makes it a ten-hour day rather than a six-hour one.
Allow the evening either way
Even the five-hour trips take the middle out of your day in Ljubljana.
Best time
When to go
The cave runs all year and the temperature underground barely notices the calendar, so the season changes the surface half of the day — the drive, the castle, the light on Lake Bled and how many people share the platform — more than the cave itself.
Apr & May
Green karst, short queues
Spring is the easy pick: the karst is green, the castle courtyard is pleasant rather than hot, and departures still have room a few days out. Lake Bled is at its clearest before the summer crowd arrives.
June
Long days, full itineraries
Long daylight makes the ten- and eleven-and-a-half-hour days comfortable: you can do Postojna, Predjama and Bled and still be back in Ljubljana while it is light. Book a week or two ahead.
July & Aug
Peak season, coolest place in Slovenia
The busiest months above ground, and the two when the cave is the most welcome place in the country, because it stays cool while the streets do not. The most-booked trips sell through first, so hold a date early.
Sept & Oct
Autumn colour, quiet platforms
Autumn turns the Notranjska forests and the slopes above Bled, the coach parks thin out, and the walking part of the cave tour is unhurried again. Days are shorter, so the earlier departures suit the long itineraries.
Worth knowing
Six things that aren't in the listing
01
The train is the point. A railway carries you into the rock before the walking starts, and every trip on this page includes it, so the visit starts well inside the hill rather than at the door.
02
Check whether the entry tickets are in the fare. Four listings here include entry to both the cave and Predjama Castle. The others cover transport and a guide and arrange a discount at the door — usually 10 per cent.
03
The castle is part of the same ticket on most trips. Predjama is half an hour past Postojna and every one of the thirteen listings takes you to both, which is why comparing a cave-only price with a cave-and-castle price is comparing two different days.
04
Take a layer, whatever the month. The listings say it plainly: the air underground stays cool all year. Stepping out of a Slovenian summer afternoon into the cave is the change people are least prepared for.
05
Small group means eight people. Several of these trips run minivans capped at eight passengers, and the group you drove out with is the group you walk the cave with.
06
Book ahead for the slot, not a lower fare. Cave entry runs to timed slots, and the early ones go first. Free cancellation runs on the listings here, so an early date is low risk.

Common questions
Ljubljana to Postojna Cave, answered
How much is a trip from Ljubljana to Postojna Cave?
Fares on this page run from $57 to $194. The cheapest are the small-group minivans: $57 for six hours and $78 for five, both covering transport and a guide, with the entry tickets bought at the door. Our top pick, at $131, includes entry to both the cave and Predjama Castle. The long days with Lake Bled or Piran run $103 to $194.
Is there really a train inside Postojna Cave?
Yes — that is the thing the cave is known for. A railway runs from the entrance into the rock and carries visitors through the first galleries before the walking part begins, and every trip on this page includes it. It is why the listings talk about boarding a train rather than walking in.
How long does the trip from Ljubljana take?
Five to six hours if the day is Postojna Cave and Predjama Castle, which is what six of the thirteen trips here do. Ten to eleven and a half hours if Lake Bled or Piran is added, and most of that extra time is road. Postojna itself is about an hour from Ljubljana, and Predjama another half hour past it.
Do the trips include the entry tickets?
Four of them do: entry to Postojna Cave and Predjama Castle is in the fare, and the Lake Bled trip carries Bled Castle as well. The rest cover the transport, the driver-guide and in several cases a skip-the-line service, and arrange a discount on the tickets at the door — usually 10 per cent. Each listing states which, and it is the number worth checking before the headline fare.
What is Predjama Castle, and is it worth adding?
It is a castle built into the mouth of a cave in a cliff face, half an hour past Postojna, with restored living rooms, dungeons and passages running back into the rock. Every trip here takes you to both, because the pairing is what the operators sell. If the cave is the reason you are going, the castle is the part of the day people remember second.
What should I wear inside the cave?
A layer you can put on. The listings are consistent that it stays cool underground all year, whatever the weather above, and the change is sharpest in summer. Shoes you can walk an hour in matter too: after the train you are on foot on a made path, and Predjama Castle is stairs and passages cut into rock.
Is Postojna Cave worth it?
The thirteen trips here carry 5,439 reviews between them at an average of 4.8, and the tickets-and-tour trip holds 2,655 of those on its own. What the fare buys is an underground railway into the cave, a walk through its halls, and a castle built into a cliff half an hour away — inside half a day from Ljubljana.

We say who has paid for the tickets
Four listings carry entry to Postojna Cave and Predjama Castle in the fare; the rest arrange a discount at the door. Every card and every table on this page says which.
Five hours or eleven, stated plainly
The cave and the castle are half a day. Lake Bled and Piran turn it into a long one. We lead with the length, because it decides more than the fare does.
The answer
Pick the length of the day, then check the tickets.
Every trip on this page leaves Ljubljana and rides the underground train into Postojna Cave. What separates them is how many hours the day takes and whether the entry to the cave and Predjama Castle is already in the fare. Trips start at $57, the cave is open all year, and free cancellation runs on the listings here.
