ST303 Tordas - Nadap

The ST303 Tordas - Nadap is a roughly 16-km point-to-point walking stage in Fejér County, central Hungary, gaining about 250 m of elevation across a single day. Part of the 2,500-km Sultans Trail from Vienna to Istanbul, it is rated easy and links the Vál Valley farmland with the ancient granite Velence Hills above Lake Velence.

About the ST303 Tordas - Nadap

The ST303 Tordas - Nadap stage is one numbered segment of the Sultans Trail, a 2,500-kilometre cultural walking route that runs from St. Stephen's Cathedral in Vienna to the Süleymaniye Mosque in Istanbul, crossing nine countries: Austria, Slovakia, Hungary, Croatia, Serbia, Bulgaria, Greece and Turkey. The trail was developed by a Netherlands-based NGO, "Sultans Trail – A European Cultural Route," and carries an official Council of Europe cultural-route association. It traces, in reverse, the 141-day march that Sultan Süleyman the Magnificent led toward Vienna in 1529, reframing a historic line of conflict as what the foundation now calls "a path of peace and a meeting place for people of all faiths and cultures."

In Hungary the main route threads through Győr, Esztergom, Szentendre, Budapest, Székesfehérvár, Dunaföldvár, Szekszárd and Mohács. The ST303 segment sits on the south-western approach to Székesfehérvár, carrying walkers out of the gentle Vál Valley (Váli-völgy) at Tordas and up into the Velence Hills (Velencei-hegység), finishing in the small wine village of Nadap. Tordas is a village of about 1,500 residents roughly 35 km south-west of Budapest; Nadap, even smaller at around 500 inhabitants, sits on the northern flank of the Velence Hills above the 26-square-kilometre Lake Velence, Hungary's third-largest lake.

This is not a mountain stage. The Velence Hills top out at Meleg-hegy (352 m), one of the oldest exposed granite ranges in Hungary, so the day is a rolling walk through farmland, vineyards and dry oak woodland rather than a climb. That makes ST303 a realistic choice for newcomers to multi-day European walking and for anyone wanting a relaxed introduction to the Sultans Trail before tackling its harder Balkan sections.

Route Overview & Stages

The ST303 designation covers the Tordas-to-Nadap leg as a single day. Because the Sultans Trail is waymarked but quiet, the segment is best understood as three natural sub-sections, summarised below. Distances are approximate and based on the standard Sultans Trail Hungarian itinerary.

At an easy pace of 3.5–4 km/h on largely flat to gently rolling terrain, most walkers complete ST303 in four to five hours including breaks. There is no technical ground, no exposure and no river crossing — the main navigational task is staying on the waymarked field tracks between villages, where the trail can briefly merge with farm roads.

Highlights & Points of Interest

• Tordas Arboretum (Tordasi Arborétum) — a historic landscaped park beside the former Sajnovics manor, with mature specimen trees that make an easy detour at the start of the day.
• Vál Valley (Váli-völgy) — a broad, fertile agricultural corridor of wheat, sunflower and maize that defines the first half of the route and gives wide skies in every direction.
• Kajászó village church — a small Reformed church marking the midpoint hamlet, a typical low-key stop for water and shade.
• Pázmánd vineyards — south-facing slopes on the edge of the Velence Hills where local granite soils produce light white wines.
• Velence Hills (Velencei-hegység) — among the oldest granite massifs in Hungary, with weathered "tor" boulder formations such as the Pandúr-kő rocks rising from oak woodland.
• Nadap geodetic benchmark (Nadapi szintezési ősjegy) — the historic national height reference point established in 1875, from which all Hungarian elevations were once measured; a small monument marks it above the village.
• Lake Velence panorama — on the descent toward Nadap the 26-km² lake opens up to the south, a major bird habitat and one of the warmest bathing lakes in Europe.
• Pákozd–Sukoró memorial area — just south-west of Nadap, the site of the 1848 Battle of Pákozd, the first major engagement of the Hungarian Revolution, reachable as a short add-on.

Best Time to Hike the ST303 Tordas - Nadap

The Velence Hills sit in a notably warm, dry pocket of central Hungary, which shapes the hiking calendar. April and May bring fresh greenery, flowering orchards and comfortable walking temperatures of 14–22 °C, with the field tracks usually firm after the winter wet. September and October are equally rewarding: the grape harvest is underway in Pázmánd and the oak woods of the Velence Hills turn copper, with daytime highs around 15–20 °C.

Midsummer — July and August — regularly pushes past 30 °C here, and the exposed Vál Valley offers little shade, so an early start is essential if you walk in high summer. Winter is walkable on this low, well-drained ground, but short daylight and muddy farm tracks reduce the appeal.

The single best month is May: long daylight, stable spring weather, wildflowers across the valley and the lowest insect pressure before the summer heat. As of 2026, the Sultans Trail Hungarian sections remain open and waymarked year-round with no seasonal closures, so timing is purely a question of comfort rather than access.

Practical Information

Accommodation

This is a village-to-village stage, so there are no mountain huts. Most walkers base themselves in nearby Székesfehérvár (about 15 km west of Nadap), where hotels and guesthouses run roughly €45–90 per double room. Closer to the trail, guesthouses (panzió) and rural vendégház rooms in the Lake Velence villages of Pázmánd, Sukoró and Velence typically cost €40–70 per night, often with breakfast. Around the lake several campsites operate from spring to autumn, with pitches commonly €12–20 per night plus a small per-person fee. Booking ahead is wise on summer weekends, when the lake draws Budapest day-trippers.

Getting There & Back

The whole stage sits within easy reach of Budapest. The nearest international gateway is Budapest Ferenc Liszt International Airport (BUD), about 45–60 minutes by road from Tordas. Tordas lies near the Budapest–Székesfehérvár rail line; the nearest practical railway station is at Martonvásár (about 5 km from Tordas), reached from Budapest-Déli or Kelenföld in roughly 30–40 minutes. From Nadap, the closest stations are at Velence and Kápolnásnyék on the same line, a short taxi or local bus from the village, putting you back in Budapest in about 45 minutes. Regional Volánbusz services also link the surrounding villages, though frequencies are limited at weekends, so check timetables before relying on them.

Permits & Fees

No permit is required to walk ST303. The Sultans Trail is a free, openly accessible route, and the field and forest tracks it follows carry no entry charge. There are no national-park gate fees on this stage. Costs are limited to accommodation, food and transport; if you detour to swim in Lake Velence, the managed beach areas charge a modest daily entry, typically €3–6 in season.

Gear & Packing List

ST303 is a short, low-altitude day, so a light setup is more than enough. A 30–40 litre pack handles a day walk with room for water, layers and lunch — the Abisko Hike 35 is a comfortable, well-ventilated choice for warm Hungarian valley walking. If you are linking several Sultans Trail stages and carrying overnight kit, step up to the Aether 65 or a lighter ultralight option like the Arc Haul Ultra 50L. For broader pack comparisons, see our roundup of the best ultralight backpacks of 2026.

Beyond the pack, prioritise sun protection (hat, sunglasses, SPF) for the shadeless Vál Valley, at least 1.5–2 litres of water capacity, trail shoes rather than heavy boots, and a light waterproof for spring showers. Because villages along the route have limited shops, carry your own lunch and snacks.
