Review of Slovenia’s Lake Bled and Postojna Cave day trip from Ljubljana, with castle visits, entry tickets, transport, costs, and practical tips.

“We really enjoyed this whole day tour with our tour guide Klemen. He was very friendly and tried to engage all the people in the group. He had excellent communication skills and was knowledgeable about the places and kept telling us about the history of each of the place as we crossed them. We visited Bled in the morning and Caves in the afternoon. Though it was quite busy in the afternoon our guide made sure we reach the places as quick as possible. Overall would definitely recommend this tour for those who want to see two main attractions in two different directions of the country in a single day.…”

★★★★★★★★★★3.5 · 380 reviews · 1 to 2 hours (approx.) · from $18

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.”
