These tours bundle Slovenia’s two most theatrical underground sights, and I’ve picked the ones that do both justice. An electric train carries you deep into Postojna Cave; nearby, Predjama Castle sits wedged into a cliff mouth, the largest cave castle in the world. Bring a layer, since the cave holds about 10 degrees Celsius year round.
Uncover the captivating wonders of Postojna Cave and Predjama Castle on this intriguing tour in Ljubljana - a journey that promises hidden gems and unforgettable experiences.
