Our guide, Nate, was exceptional—friendly, knowledgeable, and engaging. He answered all our questions, shared insider tips to help us make the most of our tour, and even recommended a few local restaurants (which we’ve already tried and loved). He also made a special stop at a viewing deck where we captured some amazing photos of Piran. It was an amazing day with perfect weather and an incredible guide. Each of the three stops was beautiful, unique, and picturesque.

I did two day trips with Slovenian Wander and I had a wonderful experience both times! Groups were small, guides were great and everything was timed perfectly. Would recommend them for anyone visiting Ljubljana for sure!

Nate was our tour guide and he’s excellent. He arrived on time and kept the tour interesting with tidbits of Slovenian history. The drive was smooth and the van was clean. The tour was small with only 6 people and all were respectful of the meeting time. The tour started with a trip to Piran. There was plenty of time to view the village from an elevation, followed by a stroll around the fishing port and had lunch. Piran’s famous storta is not to miss especially when paired with white wine. Our second stop was the Predjama castle which was impressively and strategically built within the opening of a cave. The last part and the highlight of the tour was the Postojna Cave. Nate timed it well so we get to be the last group to see the cave avoiding the huge throngs of tourists which made it a more relaxing experience. Overall, it was a pleasant tour with a great tour guide who managed the time efficiently.
Great day drip

This is among the few tours from Ljubljana that cover Piran, a beautiful coastal city by the Adriatic Sea, overseeing both Italy and Croatia. Our tour guide Nate made the right decision to go to Piran in the morning when there was a lot of sunshine and then Postojna Cave and Prejama Castle in the afternoon when it was less busy. Nate gave us very good introduction of Slovenian history and culture along the way. He was very friendly and tried to answer all our questions in the best possible manner. This is a tour I highly recommend if you have more than one day in Ljubljana.
Highly recommend

Our first encounter with this tour group started with emailing Matic, and he was so patient and helpful in answering everything. We had no hesitation in booking the tour with Matic after his prompt response and helpful advice. We had a wonderful time on this tour with Nates, our guide. He was very knowledgeable, polite, helpful and kind. We really enjoyed this type of smaller group experience as it was more intimate and made it easier to make friends. Nates picked us up near our Airbnb, and recommended to all of us in the group that we will start the tour with a stop at Piran first. This stop is usually the last stop but we were glad he made this decision as Piran gave us the opportunity to enjoy the beautiful weather, and enjoy our lunch. The next stop to Predjama Castle and finally to Postojna Caves was absolutely the perfect highlight to end the tour, as he saved the best for last. We highly recommend this tour with Slovenian Wander. If you are reading this, think no more, just book this tour now without any hesitation.
See the best of charming Slovenia!
