About
The mystic underground of the Postojna Cave, most notorious karst cave in the world, with the Predjama Castle, and the iconic Bled with the scenic lake, the 12-century castle and wooden boats to paddle your way to the only true island in Slovenia.
From Ljubljana reach Bled, the magnificent Alpine resort with the only true island in Slovenia. For centuries it has been the symbol of natural beauty and home to fairy tales. Ascend the old 12th-century castle, perched on top of a steep cliff with spectacular views of the lake, the famous Bled island and the surrounding peaks.
A boat ride with ‘Pletna’ – traditional boat made by local, is among the must-do things when visiting Bled. Not only because of the authentic boat experience, but a true journey back in time. Standing paddllers will take you to the island with 99 stone steps on the way to the Assumption of Mary church and the fortune bell. Make sure not to miss the Bled cream cake, the notorious local dessert famous all around Slovenia, before leaving town.
Time to head south to discover the mysteries of the Slovenian karst in the Postojna Cave. The guided tour of the cave takes you on a ride by electrical train and a walk through the beautiful passages and chambers with spectacular drop stones, pillars, limestone curtains and other extraordinary wonders of the underground world.
Continue to the idyllic village of Predjama to enjoy the medieval fairytale of the amazing Predjama Castle, the largest cave castle with its dramatic setting in the gaping mouth of a cavern halfway up a hillside. Learn about the legend of a famous knight, Erasmus – the ‘Slovenian Robin Hood’ and other local folk traditions.
