Back above ground, continue your adventure to the storybook setting of Predjama Castle. Perched high on a vertical cliff, this architectural marvel has watched over the valley for more than 800 years. Wander its secret passages as you uncover the legend of the rebellious knight Erasmus and his daring defiance of the king.
