Very good night life starting from 11 pm! Siesta recomended!
Some of bars has local music and most of them international. You can ask anybody where is good fun. In last several years on Kopaonik, I went only once in diskotheque it was almost empty. But who knows, maybe it good place now for fun.

You will probably flight to airport Kostantin the Great. It is local airport, small one so don't be disappointed! From airport you will travel by bus (up to two hours trip). As you start rising to Kopaonik you may see the snow as well, but if there is no snow, still there could be a lot of snow on the top of Kopaonik, so don't be dissapointed again

Al last, if snow doesn't appear, you will find proper substitute!

Have a nice time in Serbia.
