Ljubljana: Karst & Coast Full-Day Trip

1. Ljubljana: Karst & Coast Full-Day Trip

Discover the Slovenian coast and the Karst region on this full-day trip. Your first stop is the Skocjan Caves, one of the largest and most fascinating Karstic sites in Europe, where the Reka River runs 200 meters below the surface. Next, stop at a local tavern and taste the famous Karst air-dried prosciutto. It is easy to see why locals believe it to be the best prosciutto in the world, especially when accompanied by a local Teran wine. Head on to Lipica, which is the homeland of the white Lipizzaner – the breed of horse made famous by the Spanish Riding School of Vienna. Continue through the coastal towns of Koper, Izola and Portoroz to reach everyone’s favorite spot on the Slovenian coast – Piran. Lose yourself in its narrow, medieval streets and enjoy some free time over an exquisite seafood meal in one of the many local restaurants or cafes. One last stop at Predjama Castle on the way to Ljubljana. Discover the secrets of the largest cave castle (Guinness World Records!), located on a 123-meter high cliff and learn about the local Robin Hood, the legendary knight Erazem.

Piran: Postojna Cave and Predjama Castle

3. Piran: Postojna Cave and Predjama Castle

Your tour will begin with Postojna Cave, one of the best-known caves in the world. It is also the greatest tourist attraction in Slovenia and one of the world’s largest karst monuments. This is the only place in the world where the underground landscape can be traversed on an electric train and where you can 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. From here the tour extends to the Predjama Castle which 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 in the middle of a vertical 123-meter high cliff for more than 800 years. Its romantic appeal is further emphasized by the idyllic Lokva River, which disappears into the underground world deep below the castle. As the only preserved cave castle in Europe, the Predjama Castle offers a unique insight into the building techniques and resourcefulness of people in the Middle Ages, who were looking for and found a safe harbor for themselves right at the entrance of the cave. During a siege that took place in the 15th century, the castle provided a refuge for its best known and most notorious owner, Erazem of Predjama. The legend of the courageous robber baron Erazem, who remained undefeated until one of his servants betrayed him, is still in people’s minds, inspiring and alluring as ever. It was this safe abode of his which helped the brave knight resist the besiegers without much difficulty for more than a year.

We have loved this tour to all the participants that met that same day. I think it is the best tour that Roundabout Travel offers for the itinerary and content. The tour guide was the best I've had in Slovenia: Tusi Polonca. He was very close, cheerful and managed to keep the group very excited and united. Thank you very much Tusi!

Fun day trip to the coast and so glad we got to see the Skocjan caves with the underground canyon - breathtaking and ultimate LotR vibes. And Piran is such a beautiful seaside town - wouldn't have minded an extra hour or two here.

It was interesting and a bit disappointing at the caves as we not allowed to take pictures,but rules are rules. The tour guide was fantastic

Awesome tour! Our guide was friendly and knowledgeable. You definitely pack a lot in to one day. Worth the trip!
