On the second day of my stay in Slovenia, I faced the classic dilemma of every tourist, or visit the Postojna Cave or maybe it is better to choose Skocjan Caves ? I decided on the second option due to the fact that the Scottish caves are inscribed on the Unesco list and there is less traffic. The caves themselves and the surrounding karst areas made an amazing impression on me. I could not refuse to see the Predjama Grad castle, the most picturesque in the whole country.
