The tour starts in POSTOJNA, known for its beautiful caves, a network of 21 km of caves and galleries. These caves are especially famous and very special because of the many stalactites and stalagmites and the spaciousness of the caves. You pass small villages like the rustic hamlet of Slap Pri Vipavi, a small village with the typical old stone houses. It is positioned on the Vipava wine route, one of the most popular in Slovenia.

All the places you pass during this tour offer you luscious landscapes, excellent food and wines in vintage villages and the finishing touch is the Italian cuisine of Trieste, where you can enjoy fish dishes, freshly baked pizzas from the wood oven and biechi pasta tasty with every kind of sauce.

The daily program of the 7-day tour

The limestone caves can be visited in two ways: on the day of your arrival or on the second day of the trip either by joining the regular daily tour, or on day two by a specially arranged visit that follows the non-commercial part of the caves. However last this underground walk has to be pre-booked together with the tour.

Overnight with breakfast in Postojna

This morning you could visit the caves of Postojna, the geological wonder of the Carso plateau, which consists of about a hundred caves and corridors, which together cover about 21 km. In 185 years, there have been more than 30 million visitors. You could visit the caves with a guide who will lead you through this fairy-tale setting in 1 ½ hrs, formed by a labyrinth of many colourful stalactites and stalagmites. If you are lucky you might see the mysterious cave olm (grotto salamander). This special visit must be booked in advance. After your visit to the caves, a nice walk takes you to the village of Predjama, which has been dominated for 700 years by the castle, which was built on a 123m high rock plateau. In the castle the story is told of a very daring knight, who held an army at bay by utilising the secret of the Predjama Caves, and who met his untimely demise in less than poetic circumstances; he was literally caught with his pants down. From here, it’s a gentle stroll towards the strikingly beautiful Nanos Mountain as sun goes down behind it, ending your day with delightful home-cooking and sumptuous local wine. The route continues through meadow fields towards the mountain Nanos, at whose foot you are expected in an agriturismo with an excellent cuisine.
