Serbia

A landlocked country at the Balkan crossroads, centred on the confluence of the Danube and Sava in Belgrade, the Petrovaradin Fortress in Novi Sad and monastery groups, grilled meat and kafana culture. Prices are affordable and nightlife is lively.

History: The official language of Serbia is Serbian (Cyrillic and Latin scripts both used), and the currency is the dinar (RSD). Belgrade's Kalemegdan Fortress overlooks the confluence of the two rivers, and Novi Sad's Petrovaradin Fortress faces it across the Danube; monasteries such as Studenica and Sopoćani are listed as World Heritage for their 12th–13th-century frescoes. The most important traditional family festival in Serbia is "Slava", the feast day of each family's patron saint, with fixed rituals of family and friends dining together, lighting candles and cutting bread. The 19th-century language reformer Vuk Karadžić established the orthographic principle of "spell as you pronounce", which has profoundly influenced modern Serbian. Legend: Many epic legends circulate about the medieval hero Marko Kraljević: immensely strong and chivalrous, fighting alongside his prized horse Šarac. This is the legendary figure of folk epic, to be understood separately from the historical Prince Marko himself; epic plots must not be cited as history.

• Belgrade Kalemegdan Fortress (Kalemegdan / Beograd) — the viewpoint over the two-river confluence and the starting point for an old-town walk.
• Knez Mihailova Street and Skadarlija (Knez Mihailova / Skadarlija) — a pedestrian street and a bohemian-style dining street, with live music in the evening.
• Novi Sad and Petrovaradin Fortress (Petrovaradin / Novi Sad) — the fortress and old town across the Danube; crowds are huge during summer music festivals.
• Studenica Monastery (Manastir Studenica) — a World Heritage monastery whose frescoes and architecture represent medieval Serbian art.
• Šargan Eight narrow-gauge railway (Šarganska osmica) — a mountain "figure-8" railway, an experience route that needs advance booking.

Intercity travel is mainly by long-distance bus: Belgrade–Novi Sad about 1 hour, fare on the order of ten euros; Belgrade–Niš about 3 hours. The Belgrade–Novi Sad high-speed railway (Soko) takes about 30–50 minutes, fare on the order of a single-digit number of euros, and is currently the fastest intercity option; exact times and fares are subject to Serbian Railways' official announcements. Belgrade city bus and tram fares are cheap; free policies for some times and routes have changed, so before travelling be sure to follow Belgrade city transport's official announcements and do not rely on old guides claiming the "whole city is free". For city taxis, use ride-hailing apps (CarGo, Yandex Go and others) or licensed vehicles queuing at stations; vehicles touting at airports and nightclub doors easily overcharge. Rural and monastery routes have sparse public transport, so chartered cars or driving yourself are more practical. Parking in central Belgrade and Novi Sad is zone-based and time-limited, payable by meter, app or SMS (SMS payment needs a local SIM); parking in small towns is mostly free. Fines for travelling without a ticket, illegal parking and the like start at tens of euros, subject to official announcements.

• Red Line: Do not talk loudly or casually photograph ceremonies and frescoes in monasteries; do not laugh or pose for photos at memorial sites and war sites; do not drink and drive; when discussing sensitive political topics such as Kosovo, do not provocatively press local people on their positions.
• Taboo: The traps outsiders most easily fall into: (1) arriving empty-handed at a Serbian home, or attending a Slava without a gift — bringing wine, coffee or dessert is basic etiquette, and if the host indicates removing shoes on entering, change into slippers; (2) directly refusing the first glass of rakija in a brusque manner — the host's toast is a welcome ritual; if you really cannot drink, explain politely and take a small sip; (3) ordering a whole bottle of wine at a boat nightclub (splav) without asking the price first — some venues have high minimum spends, so confirm prices before ordering.
• Good Manners: Shake hands firmly on meeting; between friends, the cheek-kiss greeting is three times, starting from the right (subject to the other person's habit). Say "Zdravo" as a greeting and "Hvala" to say thank you. Restaurant tips are about 5%–10%. At meals, the host's urging to eat is hospitality; a first refusal is understood as politeness, and accepting on the second offer is more natural. Ask the subject's consent before taking photos.

The currency is the dinar; the euro is informally accepted in some places but at a poor rate, so carry cash in the countryside. Night walking in central Belgrade and Novi Sad is generally safe, but still watch belongings in bar areas. Tap water is drinkable in cities (subject to local notices); in the countryside, buy bottled water. Emergency numbers: police 192, ambulance 194, general 112. Serbia is not an EU country, EU roaming does not apply, so arrange a local SIM in advance.
