It really is a great place and what is the greatest thing about it is that it is not far away from the city. It actually is on the very rim of my town and from the main square of Niš by car you can get there in 15 minutes with traffic. My friends an me, we often go with our bicycles to do what the people in pictures do. It is natural warm water and it has a spring there so they made canals for all of us to use it. I believe that the hill is a inactive volcano hence the warm water. From my home I ride my bike 20 minutes to get there.
