Niš is a city in Serbia. Niš is the administrative center of the Nišava District. Niš (pronounced: 'neesh') is an important crossroad between central Europe and the middle East, and assumes the central position in the Balkan peninsula. It is situated in southeast Serbia, with the coordinates - Latitude: 43° 19' 29 N, Longitude: 21° 54' 12 E. It is located in Niš Valley and surrounded by a number of mountains, two rivers, two beautiful gorges, and numerous sites of historical importance from various periods. Some approximate distances: Niš - Belgrade 240km, Niš - Sofia 150km, Niš - Skopje 200km, Niš - Thessaloniki - 400km. Niš is a must see historical city for any traveler passing through on his way to Greece or the Middle East. The streets of this 1/4 million University city are buzzing with life.
The European motorway E75 routes through Niš. From the north, you may use any highway from the Hungarian border over Novi Sad and Belgrade to Niš. From the northwest, you can travel over Austria, via Slovenia and Croatia to Belgrade and then to Niš. These are all modern highways, including the section Belgrade-Niš. It is a fast road with six lanes and 120km/h speed limit, which locals seldom observe as the road is in a pretty good shape. Beware of the police, though. At this speed, travel time from Belgrade is usually two hours. The highway continues towards the Bulgarian border, and then turns into a narrower mountainous road to Sofia. The other direction of the highway branches to the south, towards North Macedonia and Greece. Tolls are paid on highways.
Almost all buses traveling from the northwest into Bulgaria or further southeast to Turkey will stop in Niš. All buses traveling between Belgrade and Greece or Macedonia will stop in Niš. An average bus ride from Belgrade will take three hours, but make sure you opt for a 'direct' bus from Belgrade central bus station, as some buses will stop in a dozen towns on the way, sometimes getting out of the highway, and prolong the ride considerably. The bus station is just a couple of blocks north of the river. The quickest route from the bus station to the main square (Trg Kralja Milana) is to go left down the side road past all the market stalls and the covered market. This takes you to the fortress entrance from where you can cross the river and head towards the obvious Ambassador hotel.
Railway links include international trains from Thessaloniki, Greece to Ljubljana, Slovenia, via Skopje, Niš, Belgrade and Zagreb, as well as Istanbul, Turkey - Vienna, Austria via Sofia, Niš, Belgrade and Budapest. Another important railway link is the one to Bar, Montenegro, which connects Niš with the Adriatic sea. The trains are slow, not very clean, and still in the seventies style, but tickets are cheap, the scenery is sometimes beautiful, and sleeping cars are usually an option. The train station is 2 km west of the main square, a good half hour's walk.
Niš has an international airport named after Constantine the Great (international code: INI). Airport service is getting increasingly better. There are flights from and to European cities including Milan Bergamo, Rome - Fiumicino Airport, and Bologna (Italy), Basel-Mulhouse-Freiburg and Zurich (Switzerland), Munich Memmingen, Fridrihshafen, Han, Hanover, Karlsruhe-Airport Karlsruhe/Baden Baden, Nirnberg, Dortmund (Germany), Berlin Schoenefeld, Dortmund, (Germany), Dusseldorf Weeze (Germany), Bratislava (Slovakia), Vienna and Salzburg (Austria), Luqa Malta, Ljubljana (Slovenia), Tivat (Montenegro), Eindhoven (The Netherlands), Malmo, Gothenburg - Landvetter Airport (Sweden) and from fall 2017 Stockholm Skavsta (Sweden). Many world destinations can be connected over Zurich flight. The airport is 4km away from the city center (much closer to the town than in most European cities, but still not suitable for walking to your hotel). Apart from taxis, there are buses taking passengers from the airport to the city on regular basis (every 20-25 minutes from early morning till 9pm).
