ST204a Győr - Gönyü

The ST204a Győr–Gönyü is a roughly 20 km point-to-point walking stage in northwest Hungary, forming part of the 2,500 km Sultans Trail International Walking Network. It runs almost entirely along the flat Danube floodplain, gaining only about 30 m of elevation. Rated expert because of its place in a long-distance through-hike, the stage itself is gentle, riverside and easy underfoot.

About the ST204a Győr–Gönyü

The ST204a Győr–Gönyü is a single waymarked stage on the Sultans Trail, the long-distance cultural route that links St. Stephen's Cathedral in Vienna with the Süleymaniye Mosque in Istanbul. The full trail covers 2,500 km across eight countries — Austria, Slovakia, Hungary, Croatia, Serbia, Bulgaria, Greece and Turkey — and follows the line of Sultan Suleiman the Magnificent's 1529 campaign toward Vienna. The "ST204a" code marks this as the fourth lettered sub-stage of the Hungarian sequence, picking up where the ST203a Lipót–Győr leaves off and handing over to the next section downstream.

This stage sits in Győr-Moson-Sopron County, in the Kisalföld (Little Hungarian Plain), the broad lowland where the Mosoni-Danube rejoins the main Danube. You start in Győr, a city of about 130,000 people at the confluence of three rivers, and finish in Gönyű, a Danube-side village of around 3,000 residents with a working river port. Between them the path threads the dike-top and floodplain trails on the right bank of the Danube, with the river itself forming Hungary's border with Slovakia for much of the way.

Because the Sultans Trail is registered as part of the International Walking Network (IWN) — one of the world's most significant long-distance hiking systems — this segment is rated expert, reflecting the commitment and self-sufficiency a full through-hike demands rather than any technical climbing. On its own, ST204a is a flat, beginner-friendly half-day. The Sultans Trail is operated by the Netherlands-based Sultans Trail Foundation, which built and maintains the route with volunteers as "a path of peace and a meeting place for people of all faiths and cultures."

Route Overview & Stages

The ST204a is best understood as one link in the Hungarian Danube chain. The table below shows this stage broken into its natural walking sections, plus its neighbours on either side for context. Distances are approximate, measured along the dike and riverside paths.

Total walking for ST204a comes to roughly 20 km with negligible cumulative ascent — under 30 m across the whole stage. Surfaces are a mix of paved riverfront promenade in Győr, compacted gravel dike-top and grassy floodplain track. There are no sustained climbs, no scrambling and no exposure.

Highlights & Points of Interest

• Győr Old Town (Belváros) — one of Hungary's best-preserved Baroque townscapes, with the 11th-century Bishop's Castle and the Cathedral on Káptalan Hill marking the trail's start.
• Rába–Danube confluence — where three rivers (the Danube, Rába and Rábca) meet at Győr, a long-standing strategic crossing the Sultans Trail deliberately follows.
• Mosoni-Danube embankment — leafy riverside promenade leading out of the city before the route joins the main Danube dike.
• Danube floodplain forest — protected gallery woodland of willow and poplar between Győr and Gönyű, rich in herons, cormorants and white-tailed eagles.
• Hungary–Slovakia river border — for most of the stage the far bank is Slovak territory, with the Danube itself as the frontier.
• Gönyű river port — an active inland harbour and one of the busier Danube freight quays in the region.
• Gönyű Danube ferry quay and lighthouse — the village waterfront marks the natural end of the stage, with a small ship's lighthouse and promenade.
• EuroVelo 6 crossover — the long-distance Atlantic-to-Black-Sea cycle route shares the dike here, so you will pass cyclists and benefit from the same maintained surface.

Best Time to Hike the ST204a Győr–Gönyü

This is a lowland Danube walk with a continental climate, so timing is about heat, flood risk and daylight rather than snow. May is the single best month to hike the ST204a Győr–Gönyü: spring high water has usually receded, daytime temperatures sit comfortably around 18–23 °C, the floodplain forest is in full leaf and migratory birds are active along the river.

April and early June are strong second choices, with mild conditions and long evenings. July and August can be hot and humid on the exposed dike, regularly topping 30 °C with little shade — start early if you walk then. September and October bring crisp, stable weather and quieter paths, making autumn an excellent alternative to spring. Avoid the late-winter and early-spring snowmelt window: as of 2026 the Danube in the Kisalföld still carries a real risk of high water and localised flooding of the floodplain trail between roughly March and mid-April, when sections may be closed or submerged. Always check the current river gauge before committing in that period.

Practical Information

Accommodation

Győr offers the widest choice, from hostels at around €18–25 per dorm bed to mid-range hotels and guesthouses at roughly €45–80 for a double room. Because this stage is short, most walkers base themselves in Győr the night before. In Gönyű, options are limited to a handful of guesthouses (panzió) and riverside pensions, typically €35–55 for a double. Wild and informal camping is restricted on the floodplain, but there are basic riverside campsites near the Danube in the wider Szigetköz area charging roughly €8–14 per pitch. The Sultans Trail Foundation notes that Hungarian sections may at times require tenting, so carrying a lightweight shelter adds flexibility on a longer through-hike.

Getting There & Back

Győr sits on the main Budapest–Vienna railway line and is one of the easiest trailheads in Hungary to reach. Direct trains run from Budapest Keleti in about 1 hour 10 minutes and from Vienna Hauptbahnhof in roughly 1 hour. The nearest major airport is Vienna International (VIE), about 110 km west, with Budapest Ferenc Liszt (BUD) around 130 km east; both connect to Győr by direct train in under two hours. To return from Gönyű, local trains on the Győr–Komárom line link Gönyű station back to Győr in about 15 minutes, so the stage works neatly as a one-way day walk with a short rail hop home. Regional bus services also run between Gönyű and Győr for added flexibility.

Permits & Fees

No permit is required to walk the ST204a Győr–Gönyü, and there is no fee to access the Danube dike or floodplain paths. The trail crosses protected floodplain habitat, so keep to marked routes and observe local signage. There are no border-control issues on the Hungarian bank, but note that the river itself is the Slovak frontier — do not attempt informal crossings. Standard EU and Schengen rules apply to travellers entering Hungary.

Gear & Packing List

This is a flat, well-surfaced riverside stage, so you do not need mountaineering kit — but the Danube's open dike offers little shade and weather can turn quickly. A comfortable day pack in the 30–40 L range covers a single stage; for a multi-day Sultans Trail push, a lightweight 50–60 L pack carries food and a shelter for the tent-only Hungarian sections. Good options include the Abisko Hike 35 for day use, the 2400 Windrider for fast-and-light multi-day walking, and the larger 3400 Windrider if you carry camping gear.

Pack sun protection, a wind layer, a light rain shell, at least two litres of water (refill points are spaced out between Győr and Gönyű), and sturdy trail shoes — boots are overkill on this terrain.
