Bicycle paths are improving in larger cities. Vojvodina is relatively flat, but main roads can make for dull days. Mountain biking in summer is popular in regions including Tara National Park, Fruška Gora and Zlatibor. Picturesque winding roads come with the downside of narrow shoulders.
The international Euro Velo 6 (www.eurovelo.com) route runs through parts of Serbia including Novi Sad, Belgrade and Đerdap National Park.
Serbia is landlocked, and the only river traffic are sightseeing boats that ply mainly the Danube and Drina rivers.
Bus services are extensive, though outside major hubs, sporadic connections may leave you in the lurch for a few hours. In southern Serbia particularly, you may have to double back to larger towns.
Reservations are only worthwhile for international buses and during festivals. Tickets can be purchased from the station before departure or on board.
Car & Motorcycle
The Automobile & Motorcycle Association of Serbia provides roadside assistance and extensive information on its website. A great resource for drivers is the Planplus (www.planplus.rs) interactive online road atlas; Intersistem Kartografija publishes a useful road map of Serbia (1:550,000).
Several car-hire companies have offices at Nikola Tesla Airport in Belgrade. Small-car hire typically costs €25 to €45 per day. Check where you are not able to take the car. In Belgrade and other large towns you may have to purchase parking tickets from machines, kiosks or via SMS (in Serbian only).
Traffic police are everywhere and accidents are workaday. As of 2018, the BAC limit is 0.02%. You must drive with your headlights on, even in the daytime. An International Driving Permit is required.
Hitching is never entirely safe and is not recommended. Travellers who hitch should understand that they are taking a small but potentially serious risk. That said, it's a common means of getting around in Serbia; just use your discretion.
Serbian Railways (www.serbianrailways.com) links Belgrade, Novi Sad, Subotica, Niš and Užice in the west; check the website for smaller stations between the cities. Train enthusiasts will enjoy the scenic Šargan 8 railway in Mokra Gora.
Trains usually aren't as regular and reliable as buses, and can be murderously slow, but they're a fun way to met locals and other travellers.
