Two questions
Sixteen listings above, and they come down to how much of a day you are giving it and where you start from. The short version is half a day out of Ljubljana: the cave with its underground train, and Predjama Castle nine kilometres up the road, which almost every listing here takes in as well. The long version keeps going to Lake Bled, or to the coastal town of Piran, and fills eleven hours. From Trieste or Zagreb it is a full day either way, because the driving is on both ends. Tell us what matters and we will point at one.
See it before you pay for it
Almost every listing here is built from the same two or three stops, and which ones you take decides both the fare and the length of the day. The cave itself is the constant: an electric train carries you in under the stalactites and stalagmites, and these Postojna Cave formations Slovenia is best known for are why the operators call it the best-known cave in the world — the ticket tour with a guide is $130, rated 4.8 across 2,846 reviews. Nine kilometres on, Predjama Castle is built into the rock face, the only preserved cave castle in Europe and the largest of its kind, and it comes attached to thirteen of the sixteen listings — the shortest of them is five and a half hours from Ljubljana at $79, rated 4.9 across 490 reviews. Add Lake Bled and the day grows to eleven or eleven and a half hours, with the emerald-green lake, a pletna boat to the island and Bled Castle in it — $192, rated 4.8 across 878 reviews, is the version we send most people to.
Side by side
The city you leave from decides the length of your day more than anything else on the page. Ljubljana is about an hour of road each way, so eleven of the sixteen listings start there and the short ones finish inside half a day: $74 for the guided day trip at 4.6 across 212 reviews, $79 for five and a half hours with an English driver-guide for up to eight people at 4.9 across 490, $121 for the half-day with tickets included at 4.8 across 199, and $130 for the six-hour ticket tour that carries 2,846 reviews at 4.8. From Trieste it is a six-hour round trip to the cave and Predjama Castle at $137, 4.8 across 545 reviews. From Zagreb it is a full day of twelve to thirteen hours with Ljubljana added on the way: $134 at 4.9 across 74 reviews, $158 at 4.6 across 85, and, when the car and $302 for the group day trip, and $729 when the car and the guide belong to your group alone, priced for the group rather than per person. The longest Ljubljana days are the ones that add water and coastline: Lake Bled at $127 to $192, and ten hours that end in Piran, a small town on the Adriatic, at $118, 4.9 across 459 reviews. All of them go to the same karst underground that also holds the Pivka Cave a short way on, and all of them take the same electric train inside.

Verdict
It is the listing here that balances the three things people actually weigh: the underground passages of the cave, the lake with its island church, and entry tickets already inside the fare rather than bought at the door — rated 4.8 across 878 reviews, at $192. Keep the five-and-a-half- and six-hour half-days from Ljubljana for an afternoon that is already half full, the days from Trieste and Zagreb for the trip that starts outside Slovenia, and the private day for a group that would rather set its own itinerary.
Check dates and availability→Before you book
Sixteen listings are sold here under the same two words, and the first thing to settle is where the day starts, because that is what most of the hours are buying. Eleven leave from Ljubljana, and the road to the cave is about an hour each way: the shortest of them is five and a half hours at $79, and the lowest fare on the page is the six-hour guided trip at $74. The heaviest review record here is the tickets and tour at $130, 4.8 across 2,846. Seven listings add Lake Bled, from $127 to $192, and one adds Piran on the Adriatic at $118. One day starts in Italy: Trieste to the cave and Predjama Castle, $137 over six hours, 4.8 across 545 reviews. Four start in Zagreb and run twelve or thirteen hours, from $134 up to $729 for the private day. Settle the city and the hours first, because otherwise you are comparing an afternoon with a whole day on the road.
Two-minute check
Every listing here has the same three parts, and reading them in order settles most of the questions. The first is the transfer: an hour of road each way from Ljubljana, six hours door to door from Trieste, twelve or thirteen from Zagreb, in a shared coach, a small group of up to eight, or a private car. The second is the entry: the wording to look for is tickets included, and four of the sixteen say it in the title, which is why a day that looks dearer on the list can end up costing less at the cave door. The third is the guide, who walks the cave with you after the electric train sets you down and then takes you through Predjama Castle, where the operators tell the legend of Slovenia’s own Robin Hood. One more thing worth knowing: the underground here is home to the Postojna Cave olm Slovenia scientists call the human fish, a blind amphibian kept in the cave’s own aquarium, and the guides will show you where it lives.
How many of you are going?Most listings here are group day trips sold per person, while the private ones are priced for the whole group and several small-group tours cap the party at eight guests, so the size of your party changes which listing is the sensible one
When do you want to set off?The long days from Trieste and Zagreb leave early, because the driving sits on both ends of them; the half-day runs out of Ljubljana have later departures too, and inside the cave it stays around 10 °C whatever hour you walk in
How much of the day are you giving it?Five and a half to seven hours covers Postojna Cave and Predjama Castle out of Ljubljana; ten to eleven and a half hours adds Lake Bled or the coastal town of Piran; twelve or thirteen hours is the day out of Zagreb
You’ll get the one that fits your answers, and the thing about it that catches people out.

From $130 · 2,846 reviews
★★★★★
Almost every listing here takes Postojna Cave and Predjama Castle together, because the castle stands in its cliff nine kilometres up the road. This is the version with the heaviest record of the sixteen, 4.8 across 2,846 reviews, and the tickets to both are inside the fare. The cave part of it starts with the electric train that runs underground.

From $192 · 878 reviews
★★★★★
The long version of the day keeps going to Lake Bled: the ancient underground passages of Postojna Cave in the first half, the emerald-green lake in the second, eleven and a half hours in all. It is the listing this page points at, rated 4.8 across 878 reviews, with the cave entry tickets in the fare.
From Ljubljana: Postojna Cave & Predjama Castle Guided Trip
From $74 · 212 reviews
★★★★★
The lowest fare of the sixteen is still a guided day trip out of Ljubljana: the winding system of caverns, and a tour of Predjama Castle afterwards. A small group, with an optional audio guide, rated 4.6 across 212 reviews.
From Trieste: Postojna Cave & Predjama Castle
From $137 · 545 reviews
★★★★★
Trieste is the other city people come from, and the listing gives the day six hours: Postojna Cave, which the operator calls the best-known cave in the world, and Predjama, which it calls the only preserved cave castle in Europe. Rated 4.8 across 545 reviews.
Zagreb: Ljubljana and Postojna Cave Day Tour with tickets
From $158 · 85 reviews
★★★★★
From Zagreb the cave is a whole day, and the listings use it: Ljubljana on the way, then Postojna Cave, then Predjama Castle. Transport and the cave tickets are included, and it is rated 4.6 across 85 reviews.
From Zagreb: Postojna Cave, Bled Lake & Ljubljana - Private
From $729 · 8 reviews
★★★★★
The private listings sell the whole day rather than a seat in it: you set the itinerary through Postojna Cave, Bled Lake and Ljubljana and keep your own pace. They are priced for the group rather than per person, and this one is rated 4.5 across 8 reviews, so the record behind it is a small one.
What it really costs
Fares are per person except on the private listings, where the price covers the whole car and guide. Two things move the number: how far you travel to reach the cave, and how many stops the day holds. The short end sits between $74 and $137 — the guided day trip at $74, five and a half hours with a driver-guide at $79, the half-day with tickets at $121, the six-hour ticket tour at $130, and Trieste at $137. Above that the money buys extra places in the day: Lake Bled and Predjama together run $127, $131, $164, $182 and $192, Piran and the Adriatic $118, and the Zagreb days $134 and $158. The top of the list is the longest and the most exclusive: $228 for the seven-hour Ljubljana day with the cave park in it, $302 for Zagreb, Bled and Ljubljana, and $729 for a thirteen-hour private itinerary you set yourself, priced for the group rather than per person.

The honest answer
The cave lies about an hour from Ljubljana and the castle another nine kilometres on, and that is the whole argument for a booked day: one vehicle links the two, the entry is arranged before you arrive, and a guide walks the passages with you once the train stops. The evidence behind it is 6,561 ratings across these sixteen listings. If you want the cave and the castle and nothing else in the day, book the six-hour ticket tour at $130, rated 4.8 across 2,846 reviews — more reviews than every other listing on this page put together. If you have one full day in Slovenia and want the two sights everybody comes for, take Lake Bled and the cave at $192, 4.8 across 878. On the tightest budget the guided day trip is $74. And when the day should belong to your group alone, the private Zagreb itinerary is $729 for the whole group rather than per head, and the Zagreb, Bled and Ljubljana day trip is $302.
The day, hour by hour
The listings split by hours, not by sights. Five and a half to seven hours is the cave and Predjama Castle out of Ljubljana and back. Ten to eleven and a half hours adds Lake Bled, or the coastal town of Piran. Twelve or thirteen hours is the day out of Zagreb, because the driving sits on both ends. That one decision sets the rest of the day.
The tours leave at set times and several listings ask for notice: two hours on two of the small-group tours, ten hours on the Piran day. Most of them state that the cave entry tickets are included; the listing says so in plain words, and it is worth checking before you pay. It stays around 10 °C underground, so pack a jacket and shoes you can walk in.
From Ljubljana the cave is about an hour away, which is why the half-day listings work at all. From Trieste or Zagreb the morning is the drive, and the guide usually fills it: the Zagreb listings stop in Ljubljana on the way.
The visit starts with the electric train that runs underground, and the listings name it as part of the tour. After the ride comes the walk, with a guide, among the stalactites and stalagmites the listings describe.
The castle stands in a cliff nine kilometres from the cave, and almost every listing here takes both in the same booking. One operator calls it the only preserved cave castle in Europe; another tells the legend of Slovenia’s own Robin Hood at the walls.
This is where the short day and the long day part company. The half-day listings turn back to Ljubljana; the longer ones carry on to emerald-green Lake Bled, with a pletna boat out to the island on one of them, or to Piran on the coast.
The day trips end at the point they set off from. From Ljubljana that is early enough to have the evening; from Zagreb the return leg is the last of the thirteen hours, and the guide hands the city back to you at the end of it.
Best time of day
The long days are the ones the hour matters to, because they are sold by the whole of it: eleven and a half hours for Lake Bled and the cave with entry tickets at $192, thirteen hours for either of the Zagreb days at $158 and $729, and they leave in the morning because the road is most of what they buy. The half-days sit in either end of a day that is already busy — the cave and Predjama Castle at $79 over five and a half hours, the guided trip at $74 over six, the tickets and tour at $130 over six. The middle ground is ten to eleven hours: the Piran day at $118, the Lake Bled day tour at $131, the small-group Lake Bled day at $127. What the hour cannot change is the temperature underground, which sits around 10 °C in every month, so the jacket goes in the bag whichever departure you pick.
On the ground
The cave visit starts on the electric train that runs underground, and the listings name the ride as part of the tour.
The listings describe dramatic stalactites and stalagmites, and this is the part of the walk the photographs come from.
Predjama stands nine kilometres from the cave, and almost every listing on this page takes both in one booking.
The longer listings carry on to emerald-green Lake Bled, which is what turns half a day into ten or eleven hours.
What it's like
Almost nothing here is sold as the cave on its own. Thirteen of these sixteen listings pair Postojna Cave with Predjama Castle, and seven of them add Lake Bled to the same day, which is why the fares run from $74 to $729. Eleven leave from Ljubljana, one from Trieste and four from Zagreb, and what changes between them is where the day starts, how many sights it holds, and whether the entry tickets are already inside the price.
The heaviest review record on the page is the plainest listing of the lot. The Postojna Cave and Predjama Castle tickets and tour from Ljubljana is $130 for six hours, rated 4.8 across 2,846 reviews — more than every other listing here put together. Its operator calls the cave and the medieval castle two of the most precious jewels of Slovenia, and the fare carries the tickets to both.
Our top pick is the longer day. From Ljubljana, Lake Bled and Postojna Cave with entry tickets is $192 over eleven and a half hours, rated 4.8 across 878 reviews. It is the second heaviest record here, and it buys the two sights most people come to Slovenia for in one go: the ancient underground passages of the cave and the emerald-green lake with its island.
The shortest fares are the half days. The guided trip from Ljubljana to the cave and Predjama Castle is $74 for six hours, rated 4.6 across 212 reviews, in a small group with an optional audio guide. The cave and castle tour at $79 is five and a half hours, rated 4.9 across 490 reviews, and travels as a transfer for up to eight people with an English driver-guide. The half-day with tickets included is $121 over five and a half hours, 4.8 across 199 reviews.
Five listings put Lake Bled and the cave in the same day from Ljubljana, and our top pick is one of them. The day tour at $131, 4.9 across 288 reviews, rides a traditional pletna boat to Bled Island, walks Bled Castle, visits Predjama and takes the train into Postojna Cave. The small-group version at $127 runs eleven hours for up to eight people, 4.9 across 178. The group day trip is $164 over eleven and a half hours, 4.7 across 228, with transport included, and Slovenia’s prime attractions at $182 is ten and a half hours in a small group, 4.9 across 64.
Two listings go their own way. The tour that adds Piran, the Adriatic coastal town, is $118 over ten hours, rated 4.9 across 459 reviews, in a small group of up to eight, with skip-the-line entry, pickup and a ride on the underground train through the cave. The listing that adds Postojna Cave Park to the cave and the castle is $228 for seven hours, rated 3.8 across 4 reviews.
One listing starts in Italy. From Trieste, the cave and Predjama Castle is $137 for six hours, rated 4.8 across 545 reviews, the third heaviest record on the page. Its operator calls Postojna the best-known cave in the world and Predjama the only preserved cave castle in Europe, which is the pairing the whole page is built on.
Four listings come from Zagreb, and they are the longest days here. Ljubljana, the cave and Predjama Castle is $134 over twelve hours, rated 4.9 across 74 reviews. Ljubljana and the cave with tickets is $158 over thirteen hours, 4.6 across 85, with transport included. The day trip that adds Lake Bled is $302 over ten hours, 4.8 across 3 reviews.
The highest fare on the page is private, and it is priced for the vehicle rather than the seat. From Zagreb, the private day to Postojna Cave, Lake Bled and Ljubljana is $729 over thirteen hours, rated 4.5 across 8 reviews, with the itinerary yours to set and the pace yours to keep. The operator marks it skip the line, private group, pickup available and wheelchair accessible.
The order of the choosing is plainer than the list looks. Settle the starting city first, because that is what the hours are mostly buying: from Ljubljana the road is about an hour each way, from Trieste six hours covers the pair of sights, and from Zagreb the same pair is a twelve- or thirteen-hour day. Then settle how many sights you want in it — the cave and Predjama Castle, or those two and Lake Bled, or those and Piran. Then settle whether the group is yours. The heaviest review records here — 2,846 on the tickets tour and 878 on the Lake Bled day — are the listings that fill first.
If it is the one day you are weighing up
All three go underground into the same passages, and all three leave from Ljubljana. What changes is how much else the day holds. Lake Bled and the cave with entry tickets is eleven and a half hours and takes in the lake with its island. The tickets and tour is six hours for the cave and Predjama Castle, and it carries by far the heaviest review record on this page. The guided trip is the lowest fare here, six hours in a small group with an optional audio guide. Prices and ratings are read off the operators’ own listings.

Four things decide how it goes. First, the clock: half a day covers the cave and the castle from Ljubljana, ten to eleven and a half hours adds Lake Bled or Piran, and twelve to thirteen is what a Zagreb start costs you. Second, the address, because the entrance sits apart from the town: coaches pull up at Jamska cesta in Postojna, Slovenia, and the cave mouth is a short walk from the car park. Third, the temperature underground, which holds near 10 °C in every month, so a light jacket and shoes with grip belong in the day bag whatever the forecast says above ground. Fourth, the group: three listings cap the party at eight people with a driver-guide, one is a private car priced for the group at $729, and the rest are shared coaches, which is the difference between setting the pace yourself and keeping to a timetable.
Lake Bled and Postojna Cave with entry tickets from Ljubljana, $192, rated 4.8 across 878 reviews — eleven and a half hours that hold the underground passages of the cave and the emerald-green lake with its island, and the entry tickets sit inside the fare.
The cave and Predjama Castle tickets and tour from Ljubljana, $130 for six hours, rated 4.8 across 2,846 reviews. That is more reviews than the other fifteen listings hold together, and the fare carries entry to both.
The guided trip from Ljubljana is $74 for six hours, 4.6 across 212 reviews. The cave and castle tour at $79 is five and a half hours, 4.9 across 490. The half-day with tickets included is $121, 4.8 across 199.
Five from Ljubljana: $127 in a small group over eleven hours, $131 with the pletna boat and Bled Castle, $164 with transport included, $182 over ten and a half hours, and our top pick at $192.
Trieste to the cave and Predjama Castle is $137 for six hours, 4.8 across 545 reviews. From Zagreb: $134 over twelve hours, $158 over thirteen with tickets, and $302 with Lake Bled in the day.
From Zagreb, Postojna Cave, Lake Bled and Ljubljana to yourselves, $729 over thirteen hours, rated 4.5 across 8 reviews, with the itinerary tailored to you. The operator marks it skip the line, private group, pickup available and wheelchair accessible.
Postojna Cave holds about 10 °C all year round, so the layer you want underground is the same one in August as in January. Every listing here goes inside, and the walk through the passages is the part of the day the jacket is for.
The shortest listing is five and a half hours and the longest thirteen, and the cave is walked on foot once the train sets you down. Predjama Castle is built into a cliff, and the stairs inside it are the castle’s own.
The days from Zagreb run twelve and thirteen hours, and the Lake Bled combinations from Ljubljana ten to eleven and a half. Meals sit outside the fares unless the listing states otherwise, so a bottle and something to eat belong in the bag.
Four listings name the entry tickets in their titles; on the others the operator states what the fare covers. Lunch at Bled, the pletna boat where it is a separate item, and anything bought at the castle are paid on the day.
The cave is lit for visitors and the train runs through it, and Predjama Castle stands in the face of a cliff nine kilometres away. Those two, and Lake Bled with its island church on the seven listings that include it, are what people come back with.
Every listing here is bought from the operator through GetYourGuide, and the voucher goes to your phone. The guided trip asks to be booked at least an hour ahead, the cave and castle tour and Slovenia’s prime attractions two hours, and the Piran day ten hours.
Eleven of these sixteen leave from Ljubljana, one from Trieste and four from Zagreb, and that is what most of the hours buy. Six hours from Ljubljana and thirteen from Zagreb can cover the same two sights, so the fare on its own tells you very little.
Five and a half hours buys the cave and Predjama Castle from Ljubljana. Six hours buys the same pair with tickets, or the day from Trieste. Ten to eleven and a half hours adds Lake Bled or Piran. Twelve and thirteen hours are the days from Zagreb.
Four listings say so in the title: Lake Bled and the cave with entry tickets at $192, the tickets and tour at $130, the half-day at $121, and the Zagreb day with tickets at $158. On the rest the listing states what is covered.
The cave and castle tour travels as a transfer for up to eight people with an English driver-guide, the Piran day is a small group of up to eight, and the small-group Lake Bled day takes eight as well. The day from Zagreb at $729 is marked private group, and its fare buys the vehicle rather than a seat.
Four listings carry it with the terms printed on each one: the cave and castle tour at $79, the Piran day at $118, the guided trip at $74 and Slovenia’s prime attractions at $182.
The tickets and tour holds 2,846 reviews and the Lake Bled day 878, and between them they carry more than half of the 6,561 reviews on this page. The fare is the same wherever you buy it; what booking ahead buys is the date and the departure time you wanted.
That is why eleven listings start there and why the shortest of them is five and a half hours door to door. The same pair of sights from Trieste is a six-hour day, and from Zagreb it is twelve or thirteen.
Predjama Castle stands in the mouth of a cliff, and eleven of these sixteen listings take it together with the cave. Its operator on the Trieste listing calls it the only preserved cave castle in Europe.
The ride into Postojna Cave is named on the listings that state it — the Piran day and the Lake Bled day tour among them — and the walking starts where the train sets you down.
Three listings state that pickup is available: the cave and castle tour from Ljubljana, the Piran day and the private day from Zagreb. The rest ask you to meet the guide, and the listing names the spot when you book.
Seven listings put the lake in the same day as the cave. The day tour at $131 names the pletna boat to Bled Island and Bled Castle; the others name the lake and its surroundings.
The private day from Zagreb at $729 is marked wheelchair accessible by its operator. Where access matters, read that field on the listing rather than the description, because it is the one the operator fills in.
Best time
The cave holds near 10 °C in every month of the year, so all sixteen listings run the whole year round and the month you choose changes the journey rather than the cave. What moves is the weather on the road, the length of the daylight you have left for Predjama Castle or Lake Bled afterwards, and how busy the summer weeks are at the entrance.
Dec – Feb
Midwinter changes the road, not the cave: near 10 °C inside in every month, the same whatever the thermometer says in the car park. The short half-days out of Ljubljana suit the short daylight best — five and a half hours with a driver-guide at $79, or the six-hour ticket tour at $130, rated 4.8 across 2,846 reviews.
Mar – May
Spring is when the eleven-hour days make sense again: the cave, Predjama Castle and Lake Bled in one go at $127 to $192, or ten hours ending on the Adriatic in Piran at $118, rated 4.9 across 459 reviews. Daylight lasts long enough that the castle is still lit when you reach it.
Jun – Aug
High summer is the busy stretch at the entrance, and it is also when the underground is at its most welcome: near 10 °C while the karst above bakes. Booking a day with the tickets in the fare saves a step at the door — the half-day at $121, the ticket tour at $130, or the Trieste round trip at $137, rated 4.8 across 545 reviews.
Sep – Nov
Autumn is the easiest combination Slovenia offers: mild days on the road, the summer weeks behind you, and all sixteen listings still running. It is the window for the long ones — Lake Bled and the cave at $192, rated 4.8 across 878 reviews, the thirteen-hour day from Zagreb at $158, or a private itinerary at $729 for the group.
Worth knowing
Almost every listing here is a pair, not a single sight. Thirteen of the sixteen take Postojna Cave together with Predjama Castle, nine kilometres away, and seven of them add Lake Bled to the same day. The fare you are comparing is a day of two or three sights, which is why it runs from $74 to $729.
The starting city decides the hours. From Ljubljana the road to the cave is about an hour each way, and the shortest listing here is five and a half hours at $79. From Trieste the same pair of sights is a six-hour day at $137. From Zagreb it is twelve or thirteen hours, from $134.
Read the review counts beside the ratings. The tickets and tour carries 2,846 reviews at 4.8 and the Lake Bled day 878 at 4.8, while the day from Zagreb with Lake Bled sits at 4.8 across 3 and the seven-hour listing with the cave park at 3.8 across 4. A rating on thousands of reviews is a different measure from the same rating on a handful.
Four titles say the entry tickets are included. Lake Bled and the cave at $192, the tickets and tour at $130, the half-day at $121 and the Zagreb day at $158. On the other twelve, what the fare covers is stated on the listing itself, and it is worth reading before you compare two figures.
The cave holds about 10 °C in every month. That is why these listings run all year rather than in a season, and why the jacket matters as much in summer as in winter. The walking underground starts where the electric train sets you down.
The private day is priced for the group, not the seat. $729 from Zagreb buys the vehicle, the guide and an itinerary you set, over thirteen hours, rated 4.5 across 8 reviews. Divide it by however many of you are travelling before you set it beside a per-person fare.

Common questions
By review record it is the Postojna Cave and Predjama Castle tickets and tour at $130, rated 4.8 across 2,846 reviews — six hours, and the entry tickets to both sights are in the fare. Our top pick is the longer day: Lake Bled and Postojna Cave with entry tickets at $192, 4.8 across 878 reviews over eleven and a half hours. The two answer different questions: one is the pair of sights in an afternoon, the other is the whole of Slovenia’s shortlist in a day.
The sixteen listings on this page run from $74 to $729. The guided trip from Ljubljana is $74, the cave and castle tour $79, the half-day with tickets $121 and the tickets and tour $130. The days that add Lake Bled run $127 to $192, the days from Zagreb $134 to $302, and the private day from Zagreb is $729 for the group.
That is how most of this page is sold: thirteen of the sixteen listings take both, and the castle stands nine kilometres from the cave. The shortest of them is five and a half hours from Ljubljana at $79, rated 4.9 across 490 reviews, as a transfer for up to eight people with an English driver-guide. The operator on the Trieste listing calls Predjama the only preserved cave castle in Europe.
Seven listings here do exactly that. From Ljubljana the small-group day is $127 over eleven hours, the day tour with the pletna boat to Bled Island and Bled Castle is $131, the group day trip with transport included is $164, Slovenia’s prime attractions is $182, and our top pick with entry tickets is $192. From Zagreb the same combination is $302, or $729 privately.
Yes. An electric underground train carries visitors into the cave, and the walking through the passages starts where it sets you down. The listings that name the ride include the ten-hour day with Piran at $118, which lists it among what the fare covers, and the Lake Bled day tour at $131.
From five and a half hours to thirteen. Five and a half is the cave and Predjama Castle from Ljubljana at $79; six hours buys the tickets and tour at $130, the guided trip at $74 or the day from Trieste at $137. Ten to eleven and a half hours is what the Lake Bled and Piran combinations take, and the days from Zagreb run twelve and thirteen.
From Trieste one listing runs the cave and Predjama Castle in six hours at $137, rated 4.8 across 545 reviews. From Zagreb there are four: Ljubljana with the cave and the castle at $134 over twelve hours, Ljubljana and the cave with tickets at $158 over thirteen, the day that adds Lake Bled at $302, and the private day at $729.
Four say so in the title: Lake Bled and Postojna Cave with entry tickets at $192, the cave and Predjama Castle tickets and tour at $130, the half-day with tickets included at $121, and the Zagreb day with tickets at $158. On the rest, the operator states on the listing what the fare covers, and that is the field to read before comparing two prices.

Why trust this page
Durations, inclusions and operator names come from the live GetYourGuide listings for each tour. Prices and ratings are read off the same listings and updated with the page.
Every listing here goes into Postojna Cave, and beyond that we kept the range wide: the half-days from Ljubljana, the seven days that add Lake Bled, the day with Piran, the day from Trieste, the four from Zagreb and the private one. Nobody pays to be featured.
A Postojna Cave tour usually means two sights rather than one: every one of these sixteen listings takes Predjama Castle or Lake Bled or both in the same day, and the castle stands nine kilometres from the cave. We name the starting city, the hours and the sights on every listing rather than letting the photographs decide, because a six-hour afternoon from Ljubljana and a thirteen-hour day from Zagreb can cover the very same pair.
A ticket arranges the guide, the transport from the starting city and the place in the group, and on four of these listings the entry tickets are named in the title. What is inside the cave is the cave’s own arrangement: the electric train runs into it and the walking starts where it stops. Where entry is bought on the day, the operator states that on the listing, and so do we.
The answer
Every listing on this page goes into the same passages of Postojna Cave, and most of them take Predjama Castle nine kilometres away in the same day. What you are choosing is where the day starts and how much else it holds — the cave and the castle in five and a half hours from Ljubljana, the lake and the cave in eleven and a half, six hours from Trieste, or twelve and thirteen from Zagreb. Lake Bled and the cave with entry tickets is $192, and the lowest fare here is $74. A jacket, and book ahead.
