Postojna Cave & Predjama Castle Tour: Electric Train RideA five-hour tour from Koper combines two sites: Postojna Cave, traversed by electric train past the proteus (olm) and vast karst galleries, and Predjama Castle, a 15th-century stronghold built into a vertical 123-meter cliff face. Your guide picks you up from your hotel, cruise terminal or station and handles entry to both; the cave stays at a constant 10°C year-round, so warm layers and sturdy shoes matter.Is it for me?Book this if you're on a cruise or have a fixed schedule—the guide coordinates both sites and transport in one five-hour block, so you don't need to plan separate logistics.
