Mount Kosmaj is about an hour away from Belgrade.
At the top of the mountain is a large and impressive monument.
The mountain is full of convenient routes for hiking.
Note that the mountain is high and on cool days it can be very cold!
I recommend on the way back to help at a very tasty traditional restaurant Restaurant “Vetrenjača” Mali Požarevac- Vetrenjaca, Mali Požarevac 11235.
