Škocjan Caves – the Underground Canyons
The Škocjan Caves, located in western Slovenia, are a Karstic caves. The name Karst comes from the name of the region, in which the caves are located – the Karst Plateau or the Classical Karst. Created by the river Reka, which runs for some 30 km until it disappears under the ground.
It reappears some 40 km to the north-west, near the Italian village of San Giovanni di Duino, under the name of Timavo, just 2 of kilometers from the Adriatic Sea. Thus, Timavo is the shortest river in Italy. The ancient Romans thought of it as the “birthplace of the Sea”. Virgil mentions it 3 times: in the Eclogues, the Georgics and the Aeneid.
Furthermore, the caves include a number of breathtaking phenomena, some of which seem almost as man-made.
The village of Matavun is located at the entrance of the cave, overlooking a 80-or-so meter cliff. It’s part of the UNESCO heritage.

UnusualPlaces Field Notes
- Location
- Škocjan Caves Visitor Centre, Matavun 12, Slovenia
- Coordinates
- 45.66322, 13.98932
- Access
- Cave visits are guided and start at the Visitor Centre in Matavun. Arrive at least 30 minutes before the booked tour. Wear non-slip footwear and warm clothing (the cave is about 12°C); the route has many steps and uneven ground, and the park cautions against visiting if you have mobility difficulty, fear of heights or claustrophobia. The park may cancel tours when high water or other unsafe conditions prevent access. Check the selected date’s timetable and route before travel.
- Admission
- The 2026 adult guided cave ticket varies by month: €16 Jan–Mar and Nov–Dec; €18 Apr and Oct; €22 May, June and September; €24 July and August. Reduced senior/student and child rates vary by month. The park’s unguided Education Trail is free and separate from cave admission. Check the official date-specific schedule and ticket page before travel; tours can be cancelled when water levels make conditions unsafe.
- Time needed
- The park’s detailed route description gives 2.5–3 hours for the complete 5 km route (about 1,000 steps); it also describes an early exit after about 3 km and 500–800 steps. A separate general visitor page quotes about 1.5 hours and 3 km for the cave tour, so these figures describe different portions/itineraries rather than a reliable single duration. The operator says tours end at Exit 1 in the Big Collapse Doline in January–April and October–December. Check the route for your date and allow 2.5–3 hours for the complete itinerary.
- Best season
- The park does not name one best season. Guided departure options are more frequent in warmer months, while the cave tour uses a shorter exit route in several winter months. Check the current monthly timetable; high water can cancel access.
- Opening hours
- Cave tours run on a monthly timetable with fixed guided departures; check the official schedule and availability for your date. The caves close January 1 and December 25. Visitor Centre information hours are 09:00–16:00 in September–October, 09:00–17:00 in July–August, and shorter in other months.
