Review of Ljubljana Castle tickets, funicular options, exhibits, tower views, audio guide, value, queues, and practical tips for your visit.

“The castle is visible from the entire city, so it's easy to get excited for this visit. We chose to ride the funicular up (which I recommend as it's a steep walk). Once inside, it's easy to navigate around, including climbing the tower. The views from the castle can't be beat and thus, this is a must-do activity while visiting Ljubljana.”
