Slovenian Wander · Ljubljana
Slovenian Wander picks you up at your Ljubljana accommodation and takes up to eight people to Postojna Cave and Predjama Castle. The tickets are extra, but the agency gets you 10% off and its reviews are a perfect 5.0.

Slovenian Wander is the only operator here that collects you from your own hotel, and it messages a day ahead with the details, guests say. The minivan takes eight people at most. The listing gives about two hours at Postojna Cave and an hour and a half at Predjama Castle, though guests describe days that start at the castle, so the order shifts.
Tickets are not in the $80 fare. The agency sells the combined cave and castle ticket at EUR 44.50, which it says is 10% off, or the cave alone at EUR 29.50. That's below the EUR 49.90 adult combo on the park's own ticket page. Add it up and you land near the half day with tickets included, with a pickup at your door instead of a meeting point.
All 63 reviews are four or five stars. Guests name their guides (Nate comes up again and again) and mention help with buying tickets and finding the right cave entrance. Inside, the park's guides lead the cave and an audio guide covers the castle.

★★★★★This tour was awesome. Not only were the places beautiful and interesting to visit, but the company messaged a day ahead with information which was helpful. Samer (sorry if I misspelled!) was my guide and he was amazing.
★★★★★We enjoyed the tour with our guide Mat who knew a great deal about Ljubljana and Slovenia. The audio guide tour of the castle was very interesting and the caves were outstanding.
★★★★★Our tour guide Nate was super helpful, friendly and hilarious! He gave us great recommendations for our stay in Slovenia and answered all questions we had. He dropped us off at both locations, assisted in getting our tickets and helped navigate us to the correct locations to start our tours.
★★★★★He was a safe driver and provided good information about the tour as well as some historical perspective of Slovenia. The castle was interesting and the cave was huge and awe inspiring. At the end of the day Nate provided some local snack which was a nice treat.
