Why Don’t More Travelers Go to Klis Fortress?

Since it’s so easy to get there you may be wondering… Why don’t more people want to see the Fortress of Klis? Well, that can be chalked up to a few reasons. First off, the majority of people visiting Split are doing so to get to the islands just off the coast. 

A popular Croatia itinerary is to fly into Split or Dubrovnik, spend a couple of days, and then jet off to the beautiful islands via ferry.

There is also plenty of history to see inside Split Old Town. Specifically, sites like the Diocletianโ€™s Palace and St. Domnius Cathedral are not to be missed!

To be honest, the entire Old Town of Split is like walking through a living museum. You’ll also find so many fantastic cafes and restaurants sprinkled into this area of the city!

With that said, there are some amazing things to see just outside the Split as well. So before you make up your mind you should know more about this historic fortress in the sky.

Quick History of the Fortress of Klis

This incredible fortress has over 2,000 years of history to discover. The original structure was built in 2nd Century BC by the Illyrian tribe of Delmati. 

Upon first seeing it, you’ll notice its strategic position between the passage of the Kozjak and Mosor mountains. This gives it the perfect defensive position overlooking the Dalmatian Coast and inland areas. 

In Greek the word Kleis means “the key” and it’s easy to see the reason for the name! The settling of the Croats, along with the fall of the Roman Empire was a very important period which followed. 

The fortress of Klis seemed impenetrable from outside forces up until 1537. It was then that Captain Pter Kruciz was executed by the Ottoman empire and they took control of the castle.

It wouldn’t be until 111 years later that Venetians overtook it and added elements that can still be seen today. It’s wild to imagine how much happened here when standing on the ancient walls and looking out at the sea. What a special place to explore!

Our Trip to the Fortress of Klis

We had been staying in the UNESCO town of Trogir near Split, and using our rental car to see the sites. One day on our way to the stunning Makarska Riviera, we passed Split and couldn’t believe it. What was that fortress up in the mountains?! 

When we got home that night we found out it was Klis Fortress! Since we were going to be heading to Split for 3 nights at the tail end of our Croatia itinerary, we decided we would make the trip from Trogir while we had our car.

The drive took 30 minutes on the main highway, and before we knew it were pulling into the parking lot under the massive Klis Fortress. It should be noted that there wasn’t much parking right at the main entrance. Keep that in mind if you’re driving during the summer months.

Entering Klis Fortress

After seeing it from afar, we were surprised how truly imposing the castle was up close. We started our climb up the stairs and made it to the entrance of Klis Fortress.  The ticket price was 10 Euros each and it took us a little over an hour to see the entire castle.

Another thing that shocked us right away was how few people there were here. Even though it was mid-April before the peak tourist season, we basically had the Split fortress all to ourselves!

After entering, we started immediately wandering our way around the maze of tunnels, stairways, and viewpoints. While it is the ruins of an ancient fortress and not so put together, that only added to the mystique and rustic nature of it.

Not to mention, we were literally sharing this magnificent place with only a few other travelers!

Places Not to Miss Inside Klis Fortress

Walking inside the Fortress of Klis is like taking a step back in time. Unlike other castles we’ve been to in Europe, there were very few signs explaining the history of it. Instead, it was mostly just small placards with the names on the outside of the different rooms.

We used the pamphlet given at the entrance to guide us through the Fortress of Klis. We especially enjoyed the tunnel entrances, Tower Oprah, the Princes Residence, and St. Vids Church.

The ticket price also includes admittance into the ethno-agro park called Stella Croatica. This is where you can get a taste of authentic Dalmatian cuisine and see how people once lived and worked in the hinterland region.

Epic Views From the Fortress of Klis

One of the biggest draws to this historic fort is no doubt the views. From around every corner we seemed to have yet another unique lookout down over the Dalmatian Coast. Directly under the castle is the town of Klis, and its red rooftops enhance the picturesque mountain views.

Our favorite spot was on top the Princes Residence which is one of the highest points you have access to on Klis Fortress. It was at this moment when we truly understand the magnitude of where we were! We also enjoyed the Sperun’s position which is on the far east wing away from the entrance.

It’s unbelievable this is where royalty once stood and protected their empire. After exploring the immense castle, it’s easy to see why it was so hard to conquer for opposing armies! We loved looking down at the buildings of Split and sparkling Adriatic from here.

Is Klis Fortress Worth Visiting in Croatia? 

Yes! While there is so much to see between Split Old Town and the islands, Klis Fortress is definitely worth seeing. Even if you’re not a huge history buff, it’s worth the drive up for the views alone. 

If you miss out on this you can always head over to the Marjan Hill viewpoint which is closer to the city. Yet, we highly recommend making a little extra time for the Fortress of Klis!
