Slovenia with kids, a country made to their scale

The Postojna train, the kids’ favourite

If I had to pick just one thing, this would be it. A visit to Postojna Cave starts on a train that has been running into the cave for more than 140 years, and the Tourist Board says no other karst cave has a railway. Living inside is the olm, a blind amphibian nicknamed the human fish that can reach 100 years old. The visit lasts an hour and a half and covers about 5 km, and it’s cool all year round, so pack a jacket. Close by is Predjama Castle, set into a 123-metre cliff, with the legend of the knight Erazem and a knights’ tournament every summer. How to buy tickets without resellers is in Postojna Cave.

Bled by boat and Kekec’s land

Bled has one thing children never tire of, the pletna, the rowing boat that takes you to the island, followed by the 99 steps to the church. The castle charges €7 for children and nothing for under-6s. In Kranjska Gora, Lake Jasna has a bronze ibex and a 6-metre lookout, and the Tourist Board presents Kekčeva dežela, the land of Josip Vandot’s character Kekec, as a place for little ones. At Planica, for older children, there’s a zipline down the ski-flying hill. I’ve laid out the whole valley in Kranjska Gora.

A submarine, horses and shepherds

Pivka’s Park of Military History has a submarine, the P-913, that you can climb inside, and the Dina Large Carnivore Centre is in the same area. In the Karst, the Lipica stud farm, with more than 300 horses and guided tours, is another safe bet. And at Velika Planina, the herders’ settlement above Kamnik, children see wooden huts and try sour milk. There’s more on the submarine in the Park of Military History.

What to do with kids when it rains

That’s the worry with children in the Alps, and Slovenia has an answer. Terme Čatež in Brežice is, according to the Tourist Board, the country’s largest indoor and outdoor pool complex, open all year. In Ljubljana, the castle houses a Puppet Museum, and the family ticket with the funicular is €46 at the desk. I compare the other spas with water parks in spas in Slovenia.

Prices and practicalities with kids

Tap water is drinkable everywhere according to the Tourist Board, the emergency number is 112 and the GHIC covers medically necessary care in the public system. In winter, Ljubljana’s festive December runs from 27 November 2026 to 14 January 2027, and Volčji Potok Arboretum holds evening walks among lights from 20 November 2026 to 10 January 2027. For me, though, the best time for a family trip is summer, with lakes to swim in and long evenings.
