Review of a Ljubljana day trip to Postojna Cave, Predjama Castle, and Piran, with practical advice on timing, cost, guides, and value.

“This was the perfect day trip from Ljubljana! The castle was a must (in my opinion, better than the castle at Lake Bled), and Piran was a great addition to our time in Slovenia! Our guide was very knowledgeable about the history of Slovenia, and taking us to Piran was a smart move, as the cave was less crowded in the evening.”

Review of Ljubljana’s small-group day trip to Lake Bled, Postojna Cave, and Predjama Castle, with costs, walking, timing, and practical tips.

“We were joined to an half day tour, so we were 2 groups, our tour guide had to drop them back in town in order to continue with us for a full day, inconvenient! And because of that afternoon bad weather ruin our Bled experience. If we did not have the other group with us , we could see lake bled in the morning without rain , bad planning that was probably needed to accommodate 2 groups… disappointing. Other then this, tour guide had great personality and knowledge, we liked him.”
