Caves on the railroad cars are a must do!

The train ride into the caves, as well as the cave tour was wonderful. Everything closes early. We had the last train ride in and everything was closed when we got out. I would advise you getting in at least at 4 o’clock. It was great fun to send a postcard from deep in the caves. Our tour guide was great.

Caves were awesome. Not much time at the castle. Overall a great tour, the tour guide on the bus tried to give some history and information on Koper.

Wow! Gorgeous caves.

So so cool! Really enjoyed this! Very organized, experienced tour guide, great driver too. Includes entrance to the caves. I wish we got to stay a bit longer at the castle to go inside, it was only 15 min stop.

Must see!

Dress in layers. It is a out 50 degres Fahrenheit. So glad we went for our one day cruise port. The guide had a large bus and was standing next to a faded yellowish light orange flag near cyclone fence. The bus ride was nice...she gave facts about Slovenia. The caves are well run and if you have trouble walking they will let you remain on the open air train to go into the cave and back out. If you are in a wheel chair you could do it too...double check if they can when you onto the train. There are handrails throughout with no steps within the cave system. Smooth concrete pathways too. It is also well lit which they boast about with their audio guide. It comes in various languages. The tour first has about a fifteen minutes open air train ride. If you are really tall watch your head on the train ride. Then, there is about a 45minute walk with an audio guide. Ceilings are very high generally and well lit. It does have some humidity. Beautiful sights to see. Well worth seeing. Handrails throughout. Then it's back on the train for about 15 minutes to get back out. The bus and guide were ready when they said. There are obvious restrooms there too. These were the best caves we ever went into. I highly recommend seeing them. We also went to lake bled before....but if you had to choose one excursion the caves I recommend seeing first.

Level of exercise

If you have any mobility issues this is not for you! The description never said anything about walking uphill and down in the cave. I think everyone should know that so they know! It should have been rated hard!

Fantastic experience

Amazing! Totally exceeded our expectations Our guide Rastka was very knowledgeable about the history of the caves and the region. The caves were unbelievable! The train took us down to the main area so that we could walk around at our own pace. It was beautiful.. almost indescribable. Highly recommend!

My tour guide (Rasa) was super nice. She explained a lot of history of Koper. Very pleasant and informative. The caves were amazing (10 degrees colder than ambient, so bring a jacket)
