Ultimate Guide to the Caves of Skocjan: All You Need to Know

Slovenia has as many as 7,000 caves within its entire system. If you like the outdoors, the Caves of Škocjan are a must-visit locale. You likely heard of Postojna, but Škocjan, while lesser-known, is still among Slovenia’s most important natural treasures – and maybe in the world.

The Škocjan caves are impressive due to their unique formation. Their underground canyon is one of the largest in the world. It has the Reka River flowing in its caves and going as wide as 21 miles (34 km) towards the Adriatic Sea. For spelunkers, this is something you should see at least once in your life.

Touring the vast, underground chambers of the Škocjan Caves are something you need to do at least once if you’re in Slovenia. Here’s everything you need to know about this majestic locale.

The Exploration History of the Škocjan Caves 

The first recorded exploration of the Škocjan Caves comes from a document in 1819. This document was an official report to the government’s District Office in Sežana, in which an unknown writer describes the Škocjan Caves.

Even then, the first written sources about the caves come during the era of Antiquity. Posidonius of Apamea, a Greek politician, and explorer, had the caves marked on his published maps. They were also a part of Renaissance cartography, including the Lazius-Ortelius map from 1561 and Mercator’s Novus Atlas from 1637.

Informal explorations also happened around the late 18th century. Paintings of the cave’s internal areas are present in some French painter Louis-François Cassas’ works. Among the subjects was the Velika Dolina or Big Collapse Doline.

Twenty years after the first recorded exploration, Jakob Svetina, a master plumber from Trieste, explored 120m across Rijeka into the caves’ interior to find out how to capture water for the Trieste waterworks.

In the mid-19th century, Idrija miners recorded their deepest descent into the caves at 1476 feet (450 m) in 1851. By then, many people have seen how beautiful the Škocjan Caves are. Word of the Škocjan Caves’ beauty spread throughout Europe in the latter half of the 19th century.

The cave attracted speleologists from all over the continent. These include Dr. Adolf Schmidl, the Miller Brothers from Vienna, Anton Hanke, Viljem Putick from the Czech Republic, and Josip Marinič from Trieste. Later on, more Italians visited the caves. 

Men ran the first headlong trails from nearby villages, who were also excellent guides. The part of the caves where today’s tourist tour begins – the Silent Cave – was discovered by local guides in 1904. 

The first explorers were not interested in the cave because it is a blind sleeve without running water. In 1938, a shorter tunnel was dug from the Globočak valley for more convenient access for visitors. In 1958, electric lighting was arranged in the caves.

What is in the Škocjan Caves Regional Park? 

The Škocjan Caves Regional Park lies on the native karst of Slovenia. The caves are a critical natural monument of the park and offer some of the most breathtaking views. Their vast halls and a real underground “canyon” are some of the most awe-inspiring sights, included in the UNESCO World Heritage List since 1986.

The Škocjan Caves are also very famous for their pioneering research. The karst underground is among the most expansive biome in the world. Unusual but rich archeological finds testify to the significance of the cave from prehistoric times. 

In addition, Velika and Mala Dolina, the submerged parts of the river with deep landslides, have a rich biodiversity. They offer some of the most interesting microclimatic conditions, even for a small land area. 

Typical alpine and completely Mediterranean plants intertwine within and without, which makes the locale incredible. The rich natural heritage is complemented by a varied carpet of dry karst meadows on the surface. 

The park itself has wonderful trivia for all waiting to enjoy it: the meadows above have more different butterflies on one karst meadow compared to the whole of Great Britain. 

There are also many moths in There are especially many moths on the Škocjan Caves Regional Park. Karts are also used as watering holes that intercept rainwater, used in the past to feed livestock.

In both the protected and influential areas of ​​the park, you’ll also find a rich cultural heritage waiting for you. You’ll see a lot of this in the karst architecture and the different ethnological, historical, and art-historical monuments. 

and many archaeological sites from the Early Stone Age. Some items have found their place in the museum’s smaller museum collections, which enrich the visit of guests from all over the world.

Understanding The Abstract of Natural Heritage

When talking about the Škocjan Caves Regional Park, one of the things you’ll hear from local Slovenes is the idea of natural heritage. This concept is about the connection between man and the increasingly alienated nature. It’s not a religion, but rather a physical and metaphysical world in which man lives.

It sounds weird to hear such an abstract idea, but it hinges on our natural connection with nature. Slovenes value nature because they know they have a natural connection to it. Locals understand that they have it good because nature gives back.

Unfortunately, humanity has done a great sin against nature in recent centuries. Rapid industrialization is pushing nature to the brink. While Slovenes are doing their best to keep nature and modernity in balance, there’s still a lot of work left.

What’s In and Around The Škocjan Caves Regional Park?

The Škocjan Caves Regional Park is located on the Matična (Klasično) Karst. The Karst is home to many native products that Slovenia is proud of, including the bora, prosciutto, and Teran wine. 

Karst lies between the Adriatic Sea and a general locale where researchers are slowly exploring. Researchers are seriously moving to discover more karst forms, including karst caves and other karst phenomena. 

The rock base of the Škocjan Caves Regional Park transitions from flysch rock to limestone. This is unique to these karst locales, where the phenomena underscore the microcosm available in the area.

The regional park includes an extremely characteristic and, on a global scale, unique karst landscape. Its cave network, avalanche valleys, and individual natural monuments create the Karst architecture slowly shaped by time.

The local flora and fauna receive unique representation around the world. It’s hard to find endemic species in other places – all under exceptional coexistence in an extremely small area. 

The biological and biotical diversity is mindblowing. It is also both interesting and vulnerable at the same time. This is the reason why the employees of the park, together with the locals, pay attention to the preservation of natural ecosystems. The karst should keep its status quo.

Going In and Around The Škocjan Caves

It’s easy to feel overwhelmed by the idyllic alpine between the peaks. The wilderness and the enormous dimensions of the landslides are awe-inspiring. The cave spaces and walls are majestic, even when under the shade of darkness. 

The Škocjan Caves have a wide-spanning branched system of cave tunnels. They are up to 3.85 miles (6.2 km) long. The depth to the lowest point is 731 ft (223 m), and it’s the largest and best known natural phenomenon of the Classical Karst.

The entire park comprises as many as 11 speleological objects, the entirety of which are interconnected by Rijeka or by landslides. The changing sinks in the geological past have created a variety of landslide valleys. Many of these formed at this junction, inside under the underground cavities. 

When you go out and visit, Velika and Mala Dolina are enchanting to every visitor. Their depth of 534 ft (163 m) houses an unbelievable amount of flora and fauna. The most beautiful view of both valleys is the ones with the natural bridge and the cave that separate them, called Mikl’s barn.
