What we see

  • The underground cave train and stalactite halls

  • Predjama Castle, built into a 123 m cliff
  • The story of the robber baron Erazem
  • Karst cuisine and prosciutto tasting

How the day works

I buy the tickets in advance so we skip the queue. The cave tour takes about 90 minutes, then the castle and a stop for lunch.

Why book a private guide

I choose the right entry time, bring a warm blanket for the cave (it is 10 °C inside) and adapt the storytelling to your family's age and interests.

Combine it

It pairs well with the Lipica stud farm, Škocjan Caves or Piran and the Slovenian coast.
