Bicycle Adventure in Nature

"GKT is a unique adventure for all cycling enthusiasts who are not afraid of challenging terrain, through predominantly pristine landscapes of the Inner Carniola-Primorska region.
The organization was excellent, and the GPX route recording is accurate with no navigation issues.
Accommodation along the route is not a problem; just make sure to reserve a day in advance.
Huge compliments to the organizers for selecting a truly fantastic route with breathtaking views in stunning nature.
See you again!"

With more than 24 km, Postojna Cave is the largest tourist cave in Europe and one of the most attractive caves in the world. Take a ride on the legendary cave train and admire the magnificent work of nature through caverns, underground passages and grand halls. Meet the famous baby dragons of the world’s largest cave animal – Proteus Anguinus. 


The mighty Predjama castle has been sitting in the middle of 123-metre high rock cliff, for more than 800 years. It even appears in the Guinness Book of Records as the largest cave castle in the world. It is also part of the legend of the outlaw knight Erasmus of Predjama who sucessfully resisted the siege of the castle for more than a year before being betrayed by one of his servants.
