Find Ljubljana’s color-changing monument
Cyanometer
A cyanometer isn’t a new invention; they’ve been around for a couple of centuries. But the Cyanometer monument in Ljubljana is a bit different. Not only does this cyanometer measure the color intensity of the sky, but it also replicates it via a built-in camera that captures images of the sky, making this small monument blend seamlessly with the sky when looked at from the right angle.
Most people still don’t know about this interesting monument, mainly because it was installed a few years ago (2016). If you want to check out this quirky monument and capture some interesting photos that are very pleasing to the eye, just take a short walk along Ajdovščina Street- you can’t miss it even if you’re trying to.
Hotel recommendation nearby: Stay at Hotel Slon Ljubljana if you want to be within easy walking distance of Ajdovščina Street and Ljubljana’s city center while still having easy access to many of the city’s lesser-known attractions.
Visit Ljubljana’s most underrated museum
National Museum of Contemporary History
For such a small city, Ljubljana is home to many interesting museums that are worth visiting. That’s probably the main reason why the National Museum of Contemporary History is relatively unknown to most tourists visiting Ljubljana. Additionally, the museum changed its name several times in the past, which also made people even more confused, and today, even many locals don’t know about this interesting museum.
If you want to learn more about Slovenia’s 20th-century history, you should definitely check out this often-forgotten museum. It has some impressive items from the 20th century, ranging from weapons, films, and paintings to (formerly) classified documents.
Hotel recommendation nearby: Austria Trend Hotel Ljubljana is a comfortable option with convenient access to the museum area and works well if you plan to explore beyond the old town.
See some very rare 15th-century frescoes
Holy Trinity Church in Hrastovlje
The Holy Trinity Church is located in the village of Hrastovlje near Slovenia’s capital. In the past, Hrastovlje shared the fate of many other villages on the Balkan Peninsula that were frequent targets for the Ottoman army on many different occasions. During these attacks, villagers used to gather inside fortified churches, and this was one of them. Perhaps this dark period of Slovenian history inspired the fascinating frescoes of the so-called “Dance of Death” you can find inside the church.
These frescoes symbolize that death has no preference and in death, all people are equal. The Holy Trinity Church of Hrastovlje is one of the older monasteries in Slovenia. It is a three-tiered Renaissance church with a polygonal presbytery and a bell tower, but what makes the Holy Trinity Church special are the surprisingly well-preserved frescoes, dating back to the 15th century. You can see similar frescoes in only a few other places in Europe, but none of them are as well preserved as the ones in the Holy Trinity Church.
Hotel recommendation nearby: Dependences – San Simon Resort in Izola makes a good base if you want to combine a visit to Hrastovlje with exploring Slovenia’s coastal region.
Discover a remote limestone plateau
Nanos
Ljubljana is one of the rare European cities that didn’t replace most of its greenery with urban surface, and that’s why today it’s one of the greenest capitals on the old continent. However, it doesn’t stop there. Not only does Ljubljana have a lot of green surfaces inside the city, but there’s also a lot of forests and hills surrounding the city from all sides. This means that no matter how many tourists are around, most of these forests, hills, and mountains would never get crowded. It’s really hard to choose where to go when you have so many choices, but my absolute favorite place for reconnecting with nature in Ljubljana is Nanos.
Nanos is a high, remote limestone plateau, reaching heights of up to 1313 meters. From here, you can enjoy some of the best views Slovenia has to offer, as the plateau overlooks the Postojna basin and Vipavska Brda wine region, but you can also see just how tiny Ljubljana looks from far away. Judging by this view, you might think this place is very far from Ljubljana, but it actually isn’t- the foot of the hill is only an hour away from the capital. Once you reach the foothill, you’ll need approximately 2-3 hours to reach the top.
Hotel recommendation nearby: Hotel Center Postojna is one of the most convenient places to stay if you plan to hike Nanos and explore the surrounding nature.
See an old power station turned into art
Stara Elektrarna
Stara Elektrarna was the main power station of Ljubljana for over 50 years, but was abandoned during the 1980s, when the NGO, Bunker Institute, noticed the old, forgotten building and decided to turn it into one of the best hidden gems in Ljubljana. Today, the Old Power Station is a contemporary art venue, with numerous art exhibitions, theater performances, workshops, and other kinds of events.
Stara Elektrarna also hosted and still hosts a lot of different festivals, including the Young Lions Festival, Gibanica (a Slovenian dance festival), and the Exodos International Festival of Contemporary Performing Arts, just to name a few. Throughout the last 30 years, the old power station became a symbol of Ljubljana’s alternative spirit and another reminder that Slovenians can reuse everything and not let anything go to waste, including old, abandoned buildings.
Support the coolest project in town
The Abandoned Plants Sanctuary
Slovenians sure know how to take care of their resources, and they try not only to minimize the waste they’re making but to salvage as much nature as they can. That’s why Ljubljana is one of the greenest cities in Europe. There’s no better proof of this than the Abandoned Plants Sanctuary (Društvo zavetišče za zavržene rastline). It is a volunteer-based organization that takes plants from the dumpsters to their sanctuary and nurtures them back to health. After this, they post the plants that are ready to be adopted on their Facebook page in posts written in a way that sounds like the plant is talking to “potential adopters”.
The whole idea behind this is that plants are living creatures just like us, and they should be treated as such. It’s an initiative worthy of admiration and one that’s already making a change. You won’t find a lot of people throwing plants in the garbage anymore; most of them take them to the Abandoned Plants Sanctuary. If you want to support this project, you can visit this sanctuary and “adopt a plant,” but you have to sign a form stating that you’ll take proper care of it.
Glavna Zadružna Zveza& the Telecom Building
When searching for hidden gems in Ljubljana, you won’t find too many guides or authors mentioning the old, brutalist buildings of the 20th century, characteristic of former socialist countries. Ljubljana and Slovenia spent 45 years as a country member of the Socialist Republic of Yugoslavia, and this period left its mark on the city. Today, there aren’t a lot of old, brutalist buildings in Ljubljana, but if you’re a fan of this 20th-century architectural style, you’ll definitely enjoy a walk on Slovenska Street.
Here, you’ll find some of the most interesting remaining 20th-century buildings in Ljubljana, including the Glavna Zadružna Zveza Building, SKB Bank’s building, and the old DZS building right across the street. The buildings have the usual block-like structure, typical for brutalist buildings, and of course, a lot of raw concrete construction. It might not sound like they’re the prettiest architectural marbles, but they sure stand out among the surrounding modern buildings and just add to the city’s charm.
Hotel recommendation nearby: InterContinental Ljubljana is an excellent choice if you want to stay near Slovenska Street and explore Ljubljana’s modern architectural side.
Check out the strangest art exhibition
Kino Šiška
I know this might be one of the weirdest travel tips you’ve ever gotten, but if you’re in Ljubljana, you should definitely visit the toilet in the Kino Šiška Center. Yes, you read that right- I said the toilet! The Kino Šiška Center is quite famous among locals and even tourists, but most travelers aren’t aware that the toilet is actually an alternative art exhibition that features some very interesting artwork, including caricatures of people from Slovenia’s urban scene painted on the wall, and it appears like they are waiting in line to use the washroom.
Once you go inside, you’ll find even more graffiti and interesting caricatures peeking through the washroom doors. If you want to turn a simple thing like going to the bathroom into a fun and engaging experience and see one of the most impressive graffiti displays in Slovenia’s capital, definitely check out this place.
Hotel recommendation nearby: Hotel Meksiko provides a convenient base for reaching Kino Šiška while staying slightly outside the busiest tourist areas.
Reber
The Ljubljana Castle sure gives an amazing view of the city, making it one of Ljubljana’s main tourist attractions, and as such, this place oftentimes gets very crowded. But what if I tell you that you can enjoy an equally beautiful view of the city on a secret spot that not many others know about? If you’re looking for a peaceful getaway, just turn right on the small, narrow street that appears to lead to nowhere before the Stari Trg Square instead of walking towards the Ljubljana Castle.
Keep walking down the street, and a hundred steps later, you’ll discover Ljubljana’s ultimate gem- a place hidden between the surrounding trees that offers a beautiful view of Ljubljana. If you can visit during sunset, this part of Ljubljana has a lot of orange-roof buildings that make the view even more dramatic and even more spectacular. The best part: only a few people know about this hidden viewpoint, and hence, even locals rarely visit this place, except for lonely wanderers.
Hotel recommendation nearby: Hotel Heritage Ljubljana is ideal for staying close to Stari Trg and reaching this hidden viewpoint early in the morning or at sunset.

Get lost in the surrounding mountains
Debni Vrh
There’s a reason why Ljubljana was voted the greenest city of Europe in 2016. It’s one of the most sustainable cities in Europe, and it’s lucky enough to be completely surrounded by forests and mountains. The best part is that most of these places are off the beaten track and not too many people come here because Ljubljana has roughly 300 000 residents, and most of the tourists that visit just roam around the city.
One of these places that lie off the beaten track but are still relatively easy to reach is Debni Vrh, a small mountain range located between the valley of Besnica and the lower stream of the Ljubljanica river. Some locals go to the top on bicycles, but you can also reach it by taking a bus to Javor/K. station and keep walking up the marked route that starts with a narrow macadam road. At the top, you’ll find a wooden lookout tower with a beautiful view of the Ljubljana valley and the hills surrounding the city. If you visit once, Debni Vrh will surely become your favorite Ljubljana getaway
Hotel recommendation nearby: Ljubljana Resort works well if your goal is to spend more time outdoors while remaining connected to the city.
Give your old things a new purpose
Stara roba – nova raba
This quirky thrift store is one of the few hidden gems in Ljubljana that you won’t find in most tourist guides, but it’s becoming increasingly popular among locals. It’s an interesting flea market with a very picturesque name: Stara Roba- Nova Raba (meaning old items, new consumption). It’s a great place to buy some quirky, cheap souvenirs from Ljubljana or even donate things that you don’t need.
Ljubljana locals donate the old items that they don’t need to this store, the guys at Stara Roba- Nova Raba turn them into cool souvenirs that people would want to buy, and all the money they collect goes to the homeless people in Ljubljana. In fact, one of the main purposes of this social enterprise is to offer employment, training, and skills development to homeless people through ecologically oriented activities. By shopping here, you’re also being a responsible traveler who does something to help the city, and that’s always a good thing!
Explore a 500-year-old mercury mine
Anthony’s Shaft Mining Museum
If you’re looking for a day trip to a place with a rich heritage that combines culture, history, and a bit of nature, the Idrija Mine Museum is a great choice. The mine was closed in 1995, but before that, it was one of the largest mercury mines in the world for over a century. This turned the city of Idrija into a real technological and scientific hub during the medieval ages.
Today, a small part of the mine is accessible to the public in the form of a mining museum, and all visitors have to dress as miners before entering. The museum is located roughly one hour away from Ljubljana. To get to the museum, you have to take the intercity bus from Ljubljana to Idrija and get off at Idrija UTA station- the mine is only 300 meters away.
Hotel recommendation nearby: Hotel Jožef in Idrija is the most convenient choice if you want to fully explore the museum and spend more time discovering Idrija’s heritage.
Taste the Onion Soup served in a Bread Cup
Gostilna Sokol Ljubljana
Gostilna Sokol is a favorite among locals for its onion soup served in a bread cup- a French specialty with a Slovenian touch. This gostilna is not a very old or historical restaurant, even though it looks like it, but it’s an absolute favorite among locals due to its good food and popular prices. The gostilna is located in what seems to be a very old building in Ljubljana’s old town. The interior is furnished with old wooden objects, and the restaurant looks like a traditional, rural Slovenian gostilna. It’s one of the best hidden gems in Ljubljana to try traditional Slovenian food. Sokol’s Gostilna is located in the historic center, close to the Ljubljana City Hall.
