A very popular activity in Zagreb, the capital of Croatia is Hiking in sljeme. Sljeme is the most common name for Medvednica mountain. Medvednica could be translated as "bear mountain". It is a popular destination for skiing in winter and hiking in summer.
I had a visit before in summer 2014 but it was very difficult road for a beginner like me I only managed to reach half way to the top of the mountain.
I didn't give up and on 4th of July 2015 I was able to reach the top!
It took me around 4 hours to go up and 3 hours to go down.
