Serbia's geography splits into motorway corridors linking major towns and winding mountain roads that climb through national parks. A hire car lets you thread both into a single itinerary, stopping where buses don't go.
Novi Sad and Petrovaradin Fortress
Drive 85 km north of Belgrade on motorway E-75, roughly one hour in light traffic. Novi Sad sits on the Danube; across the river Petrovaradin Fortress towers over the old town. Park along Dunavska street or in the lot beneath the fortress walls. Any economy car handles the flat motorway run, but an automatic sedan like the Toyota Corolla makes the frequent stop-start in pedestrian zones more comfortable. Combine the trip with a detour to Sremski Karlovci wine cellars, 10 km south, for a half-day loop that returns to Belgrade by evening.
Zlatibor Mountain and Sargan Eight Railway
Head 230 km southwest from Belgrade via Cacak on two-lane route 23, allowing four hours with photo stops. Zlatibor's pine-forested plateau sits above 1,000 metres; the narrow-gauge Sargan Eight heritage railway loops through tunnels near Mokra Gora. Roads are paved but twist through valleys, so choose an automatic estate like the Skoda Octavia Combi for luggage space and relaxed hill climbs. Winter months demand tyres with the snowflake symbol; summer and autumn bring clear skies and golden larches. Fuel up in Uzice before the final climb.
Tara National Park and Drina River House
Tara National Park spreads 180 km west of Belgrade along the Drina River canyon. Take route 21 through Valjevo and Bajina Basta; the road narrows past Perucac lake, where the famous Drina River house perches on a mid-stream rock. Park at the Banjska Stena viewpoint, 1,200 metres above sea level, for a panorama across forested ridges into Bosnia. An intermediate sedan or compact SUV suits the paved but uneven surface; SUVs and pickups for mountain roads offer extra ground clearance if you plan gravel forest tracks to remote monasteries. Pack snacks - village shops are sparse after Bajina Basta.
Djerdap National Park and Iron Gate Gorge
Drive 200 km east from Belgrade along the Danube on route 34, a three-hour scenic ribbon between river cliffs and wooded slopes. Djerdap gorge, known internationally as Iron Gate, narrows to just 150 metres at Gospodjin Vir. Stop at Lepenski Vir archaeological site, Golubac fortress, and the Tabula Traiana Roman plaque carved into canyon walls. The road is two-lane asphalt, mostly flat; a manual economy car like the Renault Clio keeps fuel costs low. Afternoon light slants across the water, so start early and return by dusk. Fill the tank in Pozarevac - stations thin out past Veliko Gradiste.
Nis and Niska Banja Spa
Nis lies 240 km south of Belgrade on motorway E-75, a straight three-hour drive through rolling farmland. Serbia's third city offers Roman ruins at Mediana, Ottoman Skull Tower, and the birthplace of Constantine the Great. Niska Banja spa sits 10 km east in the foothills, where thermal springs feed open-air pools. Park near Nis fortress or in the spa's main lot. Any intermediate automatic, such as the Toyota Corolla, covers the motorway distance smoothly and leaves reserve power for side trips to Sicevo gorge or Jelasnica monastery. E-vignette is mandatory for E-75; purchase online before departure or at the first border crossing if arriving from abroad.
Subotica Art Nouveau Architecture
Subotica sits 185 km north of Belgrade near the Hungarian border, reachable in under three hours via E-75 and route 24. The town hall, synagogue, and Raichle Palace showcase Secession-era facades painted in turquoise, ochre, and gold. Park in the central square and walk the pedestrian core. A compact manual like the Skoda Fabia or Opel Corsa is ideal for narrow street parking and economical motorway cruising. Cross into Hungary with a written permission letter from your rental supplier, arranged during booking. Combine the visit with Palic lake, 8 km east, for paddleboats and lakeside fish restaurants before the return leg to Belgrade.
Kopaonik Ski Resort
Kopaonik mountain rises 280 km south of Belgrade; take E-75 to Raska, then follow route 23 uphill to the resort at 1,770 metres. Winter brings ski lifts and snowboarding; summer opens hiking trails to Pancic peak at 2,017 metres. The final 20 km twist through pine forest on a paved but steep road - winter tyres are compulsory from November to March. An automatic SUV like the BMW X5 offers confidence on icy switchbacks and space for ski gear. Book accommodation in the resort village; day trips from Belgrade are possible but tiring. Fuel and groceries are available in Raska; prices climb once you enter the resort zone.
Fruska Gora Monasteries
Fruska Gora National Park stretches 80 km west of Belgrade along a low forested ridge between the Danube and the Sava. Sixteen Orthodox monasteries - Krusedol, Novo Hopovo, Grgeteg - dot the hillsides, linked by narrow paved lanes through oak and linden woods. Start from Sremski Karlovci, 12 km south of Novi Sad, and loop clockwise through the park in half a day. Any economy manual car handles the gentle gradients; the Fiat 500 squeezes into monastery parking bays. Bring a map - mobile signal drops in the valleys - and respect monastery visiting hours, typically 08:00-18:00. Combine the route with a wine tasting in Sremski Karlovci cellars before returning to Belgrade by evening.
