Its capital, Belgrade, is a lively and upcoming European city with the Sava and Danube rivers running right trough it. It's a nice place to spend time. Stroll through Prince Michael Street, the cities main pedestrian street, or have a drink on Skadarlija, a vintage street in the spirit of old Belgrade, filled with restaurants and cafés. There are a lot of old buildings on all four banks, including the huge Kalemegdan Fortress, that has been built, modelled and remodelled by Celts, Romans, Byzantins, Serbs, Austrians and Turks over more than 2,000 years. Once an important military fortification, it now serves as central park of Belgrade with beautiful views, especially during sunset. Within the fort is a zoo, a military museum, famous churches, galleries, parks, sports fields, etc. It has a multitude of various towers and ports, and two long walking/biking paths along both rivers. Other Belgrade sights include the modern Temple of Saint Sava, the National Museum and the Old Castle. The river island Ada Ciganlija has an artificial lake and an 8 km long gravel beach, which is visited by thousands of bathers during the summer. It's a lively place with lots of entertainment, cafes and restaurants, some of which are opened the whole year round. Zemun, now part of the Belgrade urban area, developed independently for most of its history and is a pleasant area with a distinct identity. Novi Sad is another delightful city, with the Petrovaradin Fortress (one of the greatest and best preserved XVIII century fortresses in Europe) as it's main sight. The city also has a number of lovely parks that just ask for a long afternoon stroll or picnic. Sremski Karlovci near Novi Sad has a rich history, numerous monuments, museums, churches, galleries and famous wine cellars. Novi Pazar, your last stop before Kosovo, has a distinct Turkish heritage and a bunch of great monasteries in the surrounding area. Mokra Gora is a traditionally reconstructed village in the popular mountain region of Zlatibor. The village of Sirogojno is in the same region, with a nice open air museum and lots of traditional crafts on display. Very nearby is the traditional village of Drvengrad, also known as Mećavnik, which the Serbian film director Emir Kusturica built for his film Life Is a Miracle. If you've seen the villages, Zlatibor offers some great ski-resorts, hiking trails and landscapes. Or, hop on the The Šargan Eight, a narrow-gauge heritage railway running from Mokra Gora to Šargan Vitasi station (Zlatibor and Tara mountains). When it comes to the number of bridges and tunnels, and the rise of 18 per thousand, Sargan Eight is unique in Europe and a ride on the 8-shaped track is a popular pass time for tourists.
