ST3 Sultans Trail section 3: Budapest - Belgrade
This section passes through two countries, Hungary and Serbia. In Hungary, the trail passes by Ërd-Ofalu, Százhalombatta, Martonvásár, Szekesfehérvár, Dunaföldvár, Kalocsa, Gemenc National Forest, Báta, Dunaszekcsö, Moh'scs and Hercegszanto. In Serbia is passes by Sombor, Apatin, Bač, Bačka Palanka, Ilok (Croatia), Fruška Gora, Novi Sad, Petrovardin, Sremski Karlovci and Stari Slankamen befor entering Belgrade.
Leaving Budapest, the route follows the Danube southward through Nagytétény, an area known for its baroque mansion and long history as a riverside settlement on the edge of the capital. At Érd‑Ófalu, the trail climbs the ancient river terrace, a high bank shaped by Ice Age waters, before crossing the plateau toward Százhalombatta, famous for its Bronze Age tumuli and open‑air archaeological park, which preserves one of Central Europe’s most important prehistoric landscapes. From here, the path turns inland across the rolling countryside toward Martonvásár, where the Brunszvik estate recalls Beethoven’s visits, and continues through the gentle hills around Pázmánd and Nadap, the latter known for its geodetic benchmark marking Hungary’s elevation reference point. Approaching Székesfehérvár, the trail enters one of Hungary’s oldest royal cities, once the coronation and burial place of medieval kings, where the remains of the early Christian cathedral and the old town’s baroque streets reveal centuries of political and religious significance.
South of Székesfehérvár, the route crosses the wide agricultural plains toward Tác, home to the Roman city of Gorsium, one of the most extensive archaeological sites in Hungary and a major centre of the province of Pannonia. Continuing through the open fields toward Sárbogárd and Mezőfalva, the landscape reflects the vast 18th‑century reorganisation of the region under the Habsburgs, when planned settlements and large estates reshaped the countryside. The trail returns to the Danube at Dunaföldvár, marked by its medieval fortress overlooking the river, and follows the left bank southward through Harta, a village with strong Swabian heritage, and on to Kalocsa, one of Hungary’s oldest archbishoprics, renowned for its cathedral, paprika traditions, and centuries of ecclesiastical influence. From here, the path continues to Bónifok and enters the Gemenc forest, the largest floodplain woodland in Europe, where wildlife, backwaters, and dense forests create a unique natural corridor. Emerging near Pörböly and Báta, the trail crosses fields to Dunaszekcső, a site of strategic importance in Roman and medieval times, before following the riverbank to Mohács, forever marked by the 1526 battle that reshaped Hungarian history and opened the way to Ottoman rule.
Serbia.
Crossing into Serbia at Hercegszántó / Bački Breg, the route enters Vojvodina, a region shaped by centuries of shifting borders, diverse communities, and the legacy of the Habsburg Military Frontier. The trail passes through Bezdan, near the historic Franz Joseph Canal, and continues to Bački Monoštor and Sombor, the latter known for its elegant Austro‑Hungarian architecture and long role as a regional administrative centre. Following the Danube southward, the path reaches Apatin, once a major Danube Swabian town, and continues through Bač, home to one of Serbia’s most important medieval fortresses, before arriving in Bačka Palanka. Crossing briefly into Croatia at Ilok, the trail touches a town famed for its medieval castle and wine traditions, then re‑enters Serbia to climb into the Fruška Gora, a mountain rich in Orthodox monasteries and cultural heritage. Descending toward the Danube, the route passes Sremska Kamenica and Petrovaradin, whose vast fortress dominates the river, before entering Novi Sad, the vibrant cultural capital of Vojvodina. The final stretch follows the riverbank through historic Danube villages such as Stari Slankamen and Belegiš, before reaching Zemun and ultimately Belgrade, where the confluence of the Sava and Danube has shaped one of the Balkans’ most storied cities.

Roadbook
This landscape also reflects quieter continuities. Trade along the Danube endured political change: Hungarian cattle still moved west toward Austrian markets, and riverside communities adapted to life between empires. Floating mills once lined the river in great numbers, turning its current into livelihood.
Between Budapest and Belgrade, the trail connects fortresses, river crossings, and historic towns that reveal how geography shaped frontier, empire, and everyday life along the Danube.
