The bike route "Caves" runs through miracleous karst landscape and passes five bigger caves in the Postojna area: the world famous Postojna cave, where you begin your visit aboard the cave train,  only half a kilometre long, but wonderful Otoška cave, the cave below Predjama castle, where you can experience underground adventures (min. number of people: 10) and with a tunnel attached Črna and Pivka cave. It is possible to visit all of these caves, but for some of them prior arrangements has to be made. Old stories lovers, don't miss little churches on the way and so called "black", traditional kitchen in the Bukovje village! And a little advise for those, who can't get enough of the activities: the Pivka jama camp resort offers basketball, valleyball, tennis facilities and a cosy swimming pool. Cycling track is on of the 10 tracks in MTB park Notranjska.
