At the beginning of a few weeks of December, I was still in Belgrade, Serbia.
Bouldering gym, it is in 1. beogradska gimnazija (First founded school in Belgrade, Serbia).
Its gym is opened publicly, from 9PM to 11PM every day, according to my memory.
Belgrades gym opening time is very short.
It is not good point.
An another gym where I visited, is same kind of that.
And It was very clouded, and no route settings on this wall.
See you again, Belgrade!
I spent a fantastic time.
