Two days is enough for the confluence view, Zemun and one proper splav night, not enough for Ada Ciganlija too, that is what our 3-day itinerary is for. Pay in RSD, roughly 117 to the euro in 2026, and skip anything that tells you to buy a bus ticket, city transport has been free since January 2025, per the Tourist Organization of Belgrade . See the full guide for why the splavovi beat a fixed nightclub here.

Two days in Belgrade is enough for the fortress-and-museum core and nothing else, so skip the splavovi and Zemun entirely this trip. You’re paying in Serbian dinars, not euros, city transit has been free since 2025, and Kalemegdan plus Saint Sava cost nothing to walk into. Our 3-day itinerary adds the Nikola Tesla Museum; 4-day through 7-day work in Avala and a day trip to Oplenac. Book these before you go:

Three days is our 2-day plan plus a full day at Ada Ciganlija, Belgrade’s river-beach peninsula, so you are not trying to squeeze swimming into an already packed Zemun-and-cruise day. Everything prices in RSD, roughly 117 to the euro in 2026, and city transport is free, no ticket to buy anywhere on this route. Want a second nightlife night and the Belgrade Waterfront too? See our 4-day itinerary . Book these before you go:

Three days is two days of fortress-and-museum core plus one more for Tesla and Novi Beograd’s brutalism, still no splavovi or Zemun on this route. Dinars, not euros, city transit free since 2025.

Four days is the three-day fortress-and-museum core plus a slower second pass at Stari Grad, still no splavovi or Zemun here, that’s a different Belgrade trip.

Six days is our 5-day plan plus a second, more deliberate nightlife night, since one splav visit barely scratches the scene here. RSD prices throughout, roughly 117 to the euro in 2026, and every leg of this route runs on Belgrade’s free public transport. If you have a full week, our 7-day itinerary adds a slow flex day on top of this. Book these before you go: A hotel in Savamala, Dorćol or Zemun on Booking.

Seven days is our 6-day plan plus a genuinely slow flex day, because a week of splavovi, river cruises and day trips earns one morning with nowhere to be. RSD prices throughout, roughly 117 to the euro in 2026, free public transport for every leg inside the city. See the full guide for the complete rundown of what earns a spot on this route and what does not. Book these before you go:

Belgrade’s real draw is the water and what happens on it after dark: the splavovi moored along the Sava and Danube, Zemun’s calmer Austro-Hungarian quay, and Ada Ciganlija’s fake beach in summer. Pay in RSD, the dinar, not euros, roughly 117 to the euro and 103 to the dollar in 2026, both worth checking same-day. Public transport has been free for everyone since 1 January 2025, no card needed, confirmed on the Tourist Organization of Belgrade’s own site .

Belgrade runs on the Serbian dinar, not the euro, roughly 117 RSD to 1 EUR and about 103 to 1 USD in mid-2026, and Serbia is an EU candidate, not a member, so don’t budget in euros out of habit. Every regular bus, tram, trolleybus, and BG Voz commuter train has been free for every rider since 1 January 2025, no card, no ticket. Spring and autumn are the best months; indoor smoking is still legal in bars and kafanas, and sporadic anti-government demonstrations have run since late 2024, so check for planned protests before you go.
