Predjama Castle in a cave (Slovenia) – Tips + Photos

Last updated on January 24, 2022 by Claire / this article contains affiliate links (Info)

Predjama Castle is the most famous and unique castle in Slovenia. Also known as Slovenia's cave castle or Postojna Castle, it has been built in front of a Karst cave halfway up a 123m cliff. Thanks to its position, it was a proud and impregnable fortress.
Below is my guide to help you plan your visit with tips, map and photos.

Why visit the Predjama Castle in Slovenia?

The Predjama Castle (Predjamski castle) is one of the places worth visiting in Slovenia to discover its unique appearance and atmosphere.
I have read reviews of people saying it is not worth going to, and I totally disagree! 
The beautiful cliff, the interior settings, the cave at the back... the visit is quite an experience! It is one of my favorite castles in Slovenia.

Many stories and legends surround the castle. It has such an air of mystery. Some say that treasure chests are still hidden in secret passages.

Below is a short video to give you an idea of what your visit could look like:

Predjama Castle in movies and tv shows

This iconic castle has, of course, been featured in movies and tv shows but not many famous ones.
The list includes:

  • Armour of God in 1986 with Jackie Chan
  • Ghost Hunters international

Many sites reference this castle as a great way to enjoy a "Game of Thrones" like experience, However the site was not used as a filming location.

More photos after the planning tips.

Organized tours

But if you don't want to drive, no worries. Predjama is a classic and is included in day trips combined with the Postojna caves or Skojcan caves.
A smooth solution where you get dropped at each location with tickets and all.

Here are 2 options:

  • Half day trip from Bled or Ljubljana going to both Predjama Castle and Postojna Cave - See program and book
  • Full day trip from Bled or Ljubljana - it is quite a long drive but it will give you a great overview with the Predjama Castle, the Unesco side of the Skojcan caves, the Lipica stud farms (but be aware that you don't always see the horses) and the beautiful medieval coastal town of Piran (my advice - if given the choice, I would choose to not to visit the horse farm to get more time at other locations) - See program and book tour

Visit Tips

  • Predjama Castle opening hours - at least 9am to 6pm May to September and at least 10am to 4pm in Winter - see the latest on the official website here
  • Predjama Castle entrance ticket - 13€80 or can be purchased as combined tickets with cave tours
  • Time to plan your visit - Plan 1h with the audio-guide to tour the whole castle and caves
  • Difficulty - 200 steep steps up and down
  • There are several carparks - and a slope to reach the entrance
  • Bring a jacket because it can be cold inside
  • Wear proper walking shoes, it is an old castle in a cave!
  • If you choose to visit, the tour includes an audio-guide with explanations about the history and life in the Predjama fort in 15 languages.

Where to stay in the area

  • There is a good choice of accommodations close to the Postojna caves, which I recommend in order to visit the caves first thing in the morning before all the busses arrive.
  • I stayed at Postojna Cave Rooms & Apartments Proteus - Nice little apartment in the center of the small town - great restaurant - Check out photos and availability
  • Or you can stay at the Postojna Cave Hotel Jama which has fantastic reviews, it right by the entrance of the cave and offers great views - Check out photos and availabilit
  • And here is a link to the best rated accommodations in Postojna

Access & Entrance to Predjama Castle Tour

From the carpark, there is an uphill path to the ticket booth near a couple of restaurants and cafés - good ice cream there.
You can purchase combined tickets with entrance to the Postojna and Skocjan caves.

But if you want to save money, you don't have to enter, you can admire the castle and its strategic position from the outside for free. Entrance is only at the entrance gate.

Before deciding to visit the castle or not, be aware that there are lots of steps - I think around 200 with some of them quite high.

Slovenia Cave Castle - Predjama History and Facts

You first discover the castle from the distance and realize how it is set up:

Predjama Slovenia Cave Castle

Here are a few Predjama Castle facts to understand better the situation:

  • Predjama literally means 'in front of the cave'
  • Stands in a cave, approximately halfway up a 123m (415ft) high cliff 
  • Best preserved cave castle in the Alpine foothills - so it offers a lot of info about the building methods
  • Considering its situation, it was difficult to access but easy to protect - so it was cold, wet, uncomfortable but safe
  • Some elements of the castle date back to the 12th century
  • Its present appearance is from 1583
  • The castle's last owner was Prince of Windischgrätz.

Once inside it is quite fascinating to discover the combination of rocks and walls.

Predjama Castle History

Predjama is an important archeological site. Bronze age stones and roman coins have been found in the caves behind and under the castle.
Even quite recently, in 1991, silver dishes were discovered in the floor of the castle cellar during restoration.

As you can see below, they were able to collect drinking water from the water dripping along the rock walls! The cold castle may not have been the most comfortable, but it was perfect to withstand a siege.

Predjama Castle Facts

Legend of Erazem

The most famous inhabitant of the castle was the knight Erazem of Predjama.  Many legends, similar to those of Robin Hood, can be heard about him.
However, at the Vienna court, Erazem killed Marshall Pappenheim who was a relative of Emperor Frederick III. Erazem had to flee to Slovenia and barricade himself in his castle.

The Emperor sent Gaspar Ravbar to besiege the castle. The siege is said to have lasted a year as secret passages inside the caves, allowed Erazem to smuggle food in and out.  But, after bribing a servant at Predjama, Gaspar Ravbar discovered a weak spot in the impenetrable fortifications: the toilet. And Erazem was supposedly shot by a canon while there.


Predjama Castle interior - Dining Room & Kitchen

Some of the rooms inside Predjama Castle have furniture and mannequins displaying life as it probably was. Sorry for the not so good pictures, but there is not much natural light illuminating the Predjama castle interior!

Your first stop is through the castle's courtroom and the torture chamber. The chamber is very dark with a 60m deep chasm, so I don't have any good pictures.

Then you discover the Dining Room and the Kitchen. They are located in the Palatium which were the living quarters for the Lord's family
Small windows and thick walls made the environment moist and cold.

The Kitchen's fireplace is located under a natural tunnel. There is also a stone sink against the outer wall for draining.

Knight Chamber & Armory

The most interesting rooms were, in my opinion, the Knight chamber and the armory.
The Knight's room is located in the living quarters and was primarily used by the males. It includes a hidden corner where valuables were kept.

The armory used to serve as the home of the guards. You can see large displays, replica of armours and weapons. Those required strength and skills.

Protection of the "Postojna Castle"

You can also climb a steep staircase through a rock tunnel to one of the protection natural windows where guards could surveil and protect against intruders.

Access to the Predjama cave

Predjama has a network of cave passages that is 14km long with different species of bats.
Access to the cave below requires to book a special tour with equipment and all. And it is accessible only in summer because bats need to be left hibernating in Winter.

But during the visit of the castle, you can enter the cave behind. Below is the entrance - mysterious, isn't it?

Then you climb stairs to reach a platform. No stalactites or stalagmites here, but an impressive hole in the cliff behind the castle!

    Is it okay to purchase a ticket to the castle after we arrive on May 5th? We would be arriving a little past 10 a.m. We will be a party of three adults. Any problem with sell out crowds?

      The castle is more fluid than the caves. So I think it should be OK.
      (but I am not part their team, so I don’t know if it has ever be full…)
