Slovenia in One Day: Lake Bled, Postojna Cave and Predjama Castle

Lisa_F, Mar 2026

Slovenian highlights

Thomas was a friendly and informative guide. The places we stopped at were well worth a visit, particularly the caves which were absolutely stunning. However, whilst it IS stated in the detail, we hadn't fully appreciated that entry fees were on top of what we had already paid - making this a very expensive day. With hindsight, we would have sought our own transport and visited the caves and Lake Bled independently

Spectacular!

The caves were spectacular and you get to see a lot! Around every turn is another amazing sight! The castle was an added bonus and fascinating to see how it blends in with the hillside and cave. Our guide George gave us lots of great insights into the history of Slovenia on the journey there and back.

Great day trip out of Ljubljana to Lake Bled and the caves

It’s a day long trip and very enjoyable. Plenty of time to take in all the sights. A very comfortable drive with Nina who was very knowledgeable and extremely punctual. Would definitely recommend her.

Be prepared....

Yuri was a terr1fic guide. He was a wealth of information regarding the areas we drove through getting to he caves and was extremely entertaining. I will say the actual tour through the caves and the associated walking, traversing inclines and declines, was somewhat strenuous. For some reason, I thought the train ride was the bulk of the activity, but, I was so wrong. That being said, I am very glad we went as it was beautiful, and very interesting.

Amazing day

Amazing trip. The castle and then the caves. Due to foggy weather conditions in Ljubljana i thought that it wouldn't be worth going. Out further the weather changed we were able to see the scenery, then onto the castle where we walked round. From there onto the caves. This was all made very spectacular by our super guide Nate. He was very informative. Telling us the history and the dates of what had occurred in the past. I would highly recommend it.

JC Postojna Cave tour

The Postojna Cave is beyond amazing, which is one of the best places that I have ever visited. Once you see it you would never forget it. We are lucky as the weather was good and there were very few tourists around. Our tour guide is great, he made our trip easy, smooth, and fun. This is one of the a few best trips that I have booked with Viator. Highly recommend.

An Excellent Day Trip

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.
