You step off the bus and the air changes—cool, damp, and mineral-sweet. The Reka River has already vanished beneath your feet, running like a secret current that shaped a canyon the size of a city below. The guided group threads down into the Škocjan Caves, crossing the famous underground bridge while the canyon walls drop away into shadow and the sound of water dares you forward.

History
Škocjan has been recognized by UNESCO for its outstanding karst landscape; the Reka River’s underground course formed a canyon large enough to be compared to some surface gorges.
Conservation
The caves’ microclimate and bat colonies are fragile—stay on marked trails, avoid flash photography and follow guide instructions to minimize impact.
Reserve your spot on the Shared group tour to UNESCO Skocjan caves from Koper today and enjoy a trusted, highly rated experience designed to help you make the most of your adventure.
Non-slip footwear
Bring sturdy shoes with good grip—cave floors and 500 stairs can be slippery even when dry.
Dress for 9°C
Layer up: the cave stays around 9°C (50°F) so a light jacket or fleece is comfortable during the two-hour underground portion.
Reserve time for embarkation
If arriving from a cruise in Koper, notify the operator of your ship details and arrive at the kiosk 15 minutes early to avoid missed departures.
Protect wildlife and formations
Avoid flash photography and stay on marked paths to preserve bats and fragile speleothems; guides enforce these rules for a reason.
Sturdy non-slip hiking shoes
Grip and ankle support are essential on damp cave steps and uneven paths.
Warm jacket or fleece
Cave temperature is about 9°C (50°F) year-round—bring a warm layer for comfort.
Small headlamp or compact flashlight
Useful for brief surface walks or personal safety—avoid using it inside the cave unless directed by your guide.
Reusable water bottle
Carry water for the surface portions; hydration helps with steady climbs and stairs.
