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.”

“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.”

Long day and no scheduled time for lunch....we returned to Ljubljana around 1230 to drop off some people and pick up more before taking off to lake bled. Had we known there would be no break for lunch we would have brought sandwiches earlier to eat during this time. It's was essentially 2 tours combined.”
