Škocjan Caves are the most dramatic cave system in Slovenia and one of the great underground landscapes of Europe. Where Postojna Cave is a polished show cave with a train, Škocjan is a raw, vertiginous canyon: the Reka river disappears into the Karst plateau near the village of Škocjan and then runs for kilometres through galleries so large that the first sight of them stops most visitors in their tracks. The system was inscribed on the UNESCO World Heritage List in 1986, one of the first natural sites in Europe to be recognised for its underground scenery, and it is protected as a regional park. The highlight is the Martel Chamber, a vast hall whose roof and floor are lost in darkness, and the Cerkvenik Bridge, a narrow footbridge slung some forty-five metres above the roaring river with the canyon walls rising into the gloom on both sides. Visits are by guided walking tour only, which keeps the groups small and the experience unhurried, and cameras are normally not allowed inside, so you simply look. The tour ends with a short ride on a funicular, or a climb, back to the surface and the village. The cave lies near Divača, roughly an hour and a quarter by road south-west of Ljubljana, which makes it an easy half-day or full-day trip, especially if you combine it with the Slovenian coast at Piran or with the Lipizzaner horses at Lipica. Most visitors without a car join a day tour from Ljubljana, which handles the transfers and the timing of the guided departures.
How to visit
The simplest option is a small-group day tour from Ljubljana that names the caves in its title and covers the transfer, which avoids a connection by train to Divača and a short onward transfer to the park entrance. If you drive, follow the motorway towards the coast, leave at Divača and follow the signs; there is parking at the visitor centre. Tours leave at set times, with more departures in the warm months and fewer in winter, so check the schedule before you go and arrive a little early.
What to expect
The guided walk of roughly an hour and a half to two hours follows a path of several kilometres, much of it on steps, so you need sturdy shoes with a good grip, since the rock and the walkways can be wet. The temperature underground is cool and steady all year, so bring a light jacket even in summer. The route passes through the Silent Cave, with its delicate formations, then the colossal Müller and Martel halls, before reaching the canyon and the bridge.
The sound of the river echoing far below is one of the things people remember longest. The path is not suitable for pushchairs or for anyone who finds heights or long flights of steps difficult, and the guides will tell you honestly what to expect.
Making the most of it
Spend time outside before or after the tour. The village of Škocjan has a small museum, a church and trails along the sinkholes and the collapsed dolines, where the plateau shows what the underground river has done. If you have a second day, pair the caves with Postojna and Predjama, or with a coastal afternoon. Many travellers rank Škocjan above Postojna for pure atmosphere, though Postojna is easier for young children and for anyone who would rather ride than walk.
What to expect
The experience
A guided walking tour through huge underground halls and across a high bridge above the Reka river, ending with a funicular ride or climb to the surface.
Best time
Any season; the cave is the same cool temperature all year, and winter and weekday departures are the quietest.
How long
About two hours underground; half a day including the transfer from Ljubljana.
Tips
Wear shoes with good grip, bring a light jacket and expect plenty of steps; photography is normally not allowed inside.
