Slovenia is full of natural treasures and there are hundreds of activities waiting for you to try them out. If you are more of adrenaline type you can climb some pretty awesome mountains, go rafting in one of the most beautiful rivers or try out the steepest zipline in the world. I am talking about Planica zipline which is located in my home country Slovenia. I have tried it out in summer on a beautiful sunny day with not too much people around (that is actually a miracle!) and it was a great experience.
