Serbia (Serbian: Србија, Srbija) is a country located in the Balkans, in southeast Europe. It was a founder and one of the six republics of the former Socialist Federal Republic of Yugoslavia. During the summer tourists love spending their time in Belgrade and enjoy the nature of many national parks throughout the country. In winter, they are warmly welcomed to mountain resorts (one of the most popular being Kopaonik, featured on BBC as one of the best ski destinations in Europe). There are also many spa resorts such as Sokobanja, Niška Banja and Vrnjačka Banja. (Serbia Wikitravel)
