    1. From Trieste: Postojna Cave & Predjama Castle

    Postojna Cave, the queen of all caves, is the best-known cave in the world. It is also the greatest tourist attraction in Slovenia and one of the world’s largest karst (limestone) monuments. This is the only place in the world where the underground landscape can be traversed on an electric train and where you get to meet this underground kingdom’s most famous inhabitant – the proteus (olm) – up close. A fantastic web of tunnels, passages, galleries and halls, astonishing diversity of karst features, as well as easy access are certainly the main reasons for the popularity of the cave and a large number of visitors (more than 36 million of them in over 200 years). The Predjama Castle reigns over the surrounding area, not far from the Postojna Cave, in the idyllic village of Predjama. This picturesque, magnificent, defiant, mysterious, and impregnable castle has been perched up in the midd...

    Really special experience. Our guide was very knowledgeable and gave us lots of extra information about Slovenia too. Thank you!

Don't miss this tour - two incredible places in one day!

I went on this tour by myself as I am traveling alone in Trieste but my tour guide Dejan was right on time to pick me up at my hotel with my name printed on a sign. He was friendly and professional with a great sense of humor and he was very knowledgeable about the area. Our first stop was the Predjama Castle which was incredible. Dejan walked me to the entrance and helped me get my ticket then turned me loose in the castle. Be sure to keep track of the time (about) 45 minutes as the cave tour runs on a regular schedule. The Postjona Cave was incredible. Bring a light jacket as it gets chilly. You get to ride a train inside and get a guided tour after the train drops you off within the depths of the cave. Your guide is waiting for you after to drop you off back at the hotel. It was amazing! I cannot recommend enough!

Both the cave and castle are stunningly beautiful and well worth a visit. If you had to choose between the Skógar cave and Lipica stud farm tour versus the Postojna Cave and Predjama Castle tour, it would be difficult as both are beautiful in their own ways; but I would take the castle tour over the horse farm tour. Do both if you have time!

Excellent Tour

Our driver, Nicola, was very accommodating. He picked us up at our hotel at the time he said he would be there. Our first stop was at the Castle where he left us on our own and told us not to rush. Then onto the Cave where he guided us to the English speaking tour. He met up with us after the tour. He did a great job.

Really special experience. Our guide was very knowledgeable and gave us lots of extra information about Slovenia too. Thank you!

It was an amazing day, our guide was early, knowledgeable, funny and flexible. Can not recommend this tour enough.
