ST405 Smederevo - Mihajlovac

The ST405 Smederevo - Mihajlovac is a roughly 15 km point-to-point trail in central Serbia, gaining around 150 m of elevation as it follows the right bank of the Danube. Rated expert, it forms one Serbian stage of the 2,500 km Sultans Trail and links Europe's largest lowland fortress with the quiet riverside village of Mihajlovac.

About the ST405 Smederevo - Mihajlovac

The ST405 Smederevo - Mihajlovac is a single stage of the Sultans Trail, a 2,500 km cultural walking route that runs from St. Stephen's Cathedral in Vienna to the Süleymaniye Mosque in Istanbul. Carried under the International Walking Network (IWN) banner, the Sultans Trail crosses eight countries — Austria, Slovakia, Hungary, Croatia, Serbia, Bulgaria, Greece and Turkey — tracing the 1529 campaign route of Sultan Süleyman the Magnificent, who marched the 141-day journey from Istanbul to Vienna. The modern path, built by volunteers from the Netherlands-based NGO Sultans Trail – A European Cultural Route, deliberately reframes that military line as "a path of peace and a meeting place for people of all faiths and cultures."

This particular section sits in the heart of the Serbian route, between the Danube port city of Smederevo and the village of Mihajlovac to the southeast. It is a point-to-point trail of roughly 15 km, walkable comfortably in 4 to 5 hours by a fit hiker. The terrain is lowland: river floodplain, agricultural tracks, vineyard slopes and short stretches of asphalt through settlements. Despite the gentle profile, the stage carries an expert rating — not for technical climbing, but for navigation. Waymarking on the Serbian Sultans Trail is sparse compared with western Europe, and walkers frequently route-find across farmland, levees and unsignposted junctions where a GPX file is essential.

What makes the ST405 worth a day is its anchor: the Smederevo Fortress, the largest plain-built fortified town in Europe, raised between 1428 and 1430 by the Serbian despot Đurađ Branković as his new capital after Belgrade was ceded to Hungary. You leave one of the great monuments of the medieval Balkans and walk out along the same river the Ottoman armies used as their supply artery, finishing in a working Danube village far from any tourist crowd.

Route Overview & Stages

The ST405 is itself one stage of the larger Serbian Sultans Trail, which threads through Smederevo on its way from Belgrade toward Smederevska Palanka and Niš. For planning purposes the stage breaks naturally into three walking segments, summarised below.

Distances are approximate; the Sultans Trail Foundation does not publish a precise surveyed length for this section, and local routing varies depending on whether the Danube levee is passable after high water. Budget the full ~15 km as a half-day outing rather than a multi-day stage.

Highlights & Points of Interest

• Smederevo Fortress — Built 1428–1430 on a triangular plain by the Danube, it covers around 11 hectares and remains the largest lowland fortress in Europe. Its 25 towers and water-filled moat once protected the last capital of medieval Serbia.
• Despot Đurađ Branković's Small Town — The inner citadel within the fortress, the residential and administrative core where the Serbian court lived from 1430 until the Ottoman conquest in 1459.
• Smederevo Danube Quay — The riverfront promenade where the trail meets the water, with views across one of the widest sections of the Serbian Danube and barge traffic heading toward the Iron Gates.
• St. George's Church (Crkva Svetog Đorđa) — Smederevo's neo-Byzantine cathedral, completed in 1855, a useful orientation landmark as you leave the old town.
• Danube floodplain wetlands — The levee section passes seasonal marshes that draw herons, cormorants and migratory waterfowl, part of the river's wider Ramsar-recognised corridor.
• Šumadija vineyard slopes — Above the floodplain the trail climbs into gentle terraced vineyards; Smederevo gives its name to the white Smederevka grape, one of Serbia's most planted varieties.
• Mihajlovac village centre — A working Danube settlement with a small Orthodox church and local kafanas, the quiet eastern terminus of the stage.
• Smederevo WWI memorial sites — Markers near the old town recall the 1941 explosion of the fortress munitions depot, a scar still visible in the walls.

Best Time to Hike the ST405 Smederevo - Mihajlovac

The continental climate of the Serbian Danube valley shapes everything about this stage. Summers are hot — July and August routinely push past 33°C on the open floodplain, where there is almost no shade, and the levee can be airless. Winters are cold and damp, with the Danube fog (locally magla) sitting over the river well into the morning and frequent frost from December through February.

The walking windows are spring and autumn. May is the single best month to hike the ST405: daytime highs sit around 22–24°C, the floodplain meadows are green, wildflowers line the levee, and the river has usually dropped from its April high-water peak so the levee path stays dry. September is a strong second choice, coinciding with the start of the Šumadija grape harvest and offering stable, clear weather.

As of 2026, regional forecasts continue to show warming spring temperatures across the Balkans, which means the comfortable shoulder season is starting earlier — late April is now often as pleasant as mid-May was a decade ago. Whatever month you choose, check Danube water levels before you go, as high water can submerge the levee segment and force a longer road detour through Smederevo's eastern suburbs.

Practical Information

Accommodation

Smederevo, as a city of roughly 65,000 people, is the natural base. Expect small hotels and guesthouses (pansion) at €30–€55 per double room per night, and private apartments via short-term rental at €25–€45. There is no mountain hut infrastructure on this lowland route. Mihajlovac itself has very limited beds — most walkers treat it as the day's endpoint and return to Smederevo for the night, or continue by local transport. Wild camping is not formally permitted on the Serbian floodplain; if you camp, ask permission at a farm or village, which is the customary practice along the Serbian Sultans Trail. Budget travellers can find hostel-style rooms in Belgrade, 45 km west, from €15–€20 per bed.

Getting There & Back

The nearest major gateway is Belgrade Nikola Tesla Airport (BEG), about 60 km west of Smederevo, roughly a 60–75 minute drive. From central Belgrade, frequent intercity buses reach Smederevo in around 50–60 minutes; the Smederevo bus station sits a 15-minute walk from the fortress. Rail service exists but is slower and less reliable than the bus. From Mihajlovac at the end of the walk, local buses run back to Smederevo several times a day (a short 20–25 minute ride); confirm the timetable locally, as rural Serbian services thin out in the evening and on weekends. A taxi from Mihajlovac to Smederevo is an inexpensive fallback at roughly €8–€12.

Permits & Fees

No permit is required to walk the ST405 — the Sultans Trail is a free, open cultural route across public land and roads. The only paid element is the Smederevo Fortress itself, which charges a modest entry fee of around €2–€3 to access the inner citadel and museum exhibits; the outer walls and riverside approach are free to view. Bring Serbian dinars in cash, as small sites and rural buses rarely take cards.

Gear & Packing List

This is a lowland, single-day stage, so a light load is more than enough — but the expert-level navigation and the exposed, shadeless floodplain mean you should pack deliberately. A 30–40 litre daypack handles a day's water, food and a weather layer comfortably; the Abisko Hike 35 is a good fit for a comfortable day kit, while ultralight walkers carrying minimal gear will be happy with the 2400 Windrider. If you are linking several Sultans Trail stages and carrying camping kit, step up to the Arc Haul Ultra 60L.

Beyond the pack, prioritise sun protection (hat, sunscreen, sunglasses) for the unshaded levee, at least 2 litres of water capacity, sturdy trail shoes that cope with muddy floodplain tracks, and a phone or GPS loaded with the GPX track — waymarks cannot be relied on here. Carry electrolytes and high-calorie snacks; planning your day's intake matters more than people expect, as our guide on how many calories you need hiking a full day explains.

Frequently Asked Questions

When is the best time to hike the ST405 Smederevo - Mihajlovac?
May is the best month, with daytime highs around 22–24°C, dry levee paths after the spring high water recedes, and green floodplain meadows. September is a strong alternative, coinciding with the Šumadija grape harvest and stable autumn weather. Avoid July and August, when the shadeless floodplain regularly exceeds 33°C.

How difficult is the ST405 Smederevo - Mihajlovac?
It is rated expert, but not because of climbing — the elevation gain is only about 150 m over flat river terrain. The difficulty is navigational: the Serbian Sultans Trail is sparsely waymarked, and walkers route-find across farmland, levees and unsigned junctions. A loaded GPX track and offline maps are essential to complete the stage confidently.

How long does the ST405 take and what is the daily distance?
The stage is roughly 15 km and is designed as a single half-day walk rather than a multi-day route. A reasonably fit hiker completes it in 4 to 5 hours, including time at the Smederevo Fortress. There is no need to split it across days; most walkers do it as a day trip from Smederevo.

Where can I stay along the route?
Smederevo is the practical base, with small hotels and guesthouses at €30–€55 per double and private apartments from €25–€45. Mihajlovac has very limited accommodation, so most hikers return to Smederevo by bus or taxi. There are no mountain huts on this lowland route, and formal floodplain camping is not permitted.

Do I need a permit or pay any fees?
No permit is required — the Sultans Trail is a free, open cultural route on public land and roads. The only fee is entry to the inner citadel of Smederevo Fortress, around €2–€3, payable in Serbian dinars. The outer walls, riverside path and the entire walking route to Mihajlovac are free to access.
