It is therefore the most unmissable site to visit, emblematic of Slovenia as a destination. The attraction is sanitized. Postojna is nonetheless a majestic site. We start by covering a section of the 24 km of galleries, tunnels and impressive halls, aboard a small electric train before continuing your journey on foot.
