ST304 Nadap - Székesfehérvár

The ST304 Nadap–Székesfehérvár is an approximately 22-km point-to-point trail in Fejér County, Hungary, crossing the Velence Hills and gaining around 250 m of elevation in a single walking day. It forms one stage of the 2,500-km Sultans Trail from Vienna to Istanbul. Rated expert as part of that long-distance network, the leg itself is a gentle, vineyard-lined day through wine country.

About the ST304 Nadap - Székesfehérvár

The ST304 Nadap–Székesfehérvár is a Hungarian stage of the Sultans Trail, a 2,500-kilometre cultural long-distance route that links St. Stephen's Cathedral in Vienna with the Süleymaniye Mosque in Istanbul. The full trail retraces the 1529 campaign of Sultan Süleyman the Magnificent, who marched 141 days from Istanbul to the gates of Vienna. Today the path is run by the Netherlands-based Sultans Trail Foundation as a "path of peace" connecting people of all faiths and cultures across eight countries — Austria, Slovakia, Hungary, Croatia, Serbia, Bulgaria, Greece and Turkey.

This particular leg sits in the heart of the Hungarian section. It begins in the village of Nadap, tucked into the Velence Hills (Velencei-hegység) just north of Lake Velence, and finishes in Székesfehérvár, one of the oldest and most historically significant cities in Hungary. Nadap is best known among surveyors for its geodetic benchmark, the Nadap stone, the historical zero-point of Hungarian elevation measurement. From there the route works southwest through low granite hills, vineyards and oak woodland before descending onto the Pannonian plain toward Székesfehérvár.

As a registered part of the International Walking Network (IWN), the route is signed and documented as a connected international corridor rather than a stand-alone day hike. The "expert" rating reflects the demands of the entire Vienna–Istanbul journey; this single stage is far more forgiving and suits any reasonably fit walker who can manage roughly 22 km in a day. The reward is a quiet, under-touristed slice of Hungarian wine country bracketed by two genuinely interesting endpoints.

Most international hikers reach this stage as part of a longer Hungarian section that strings together Győr, Esztergom, Budapest, Székesfehérvár and Szekszárd before the trail continues south toward Mohács and Szigetvár, where the aging Süleyman died during the 1566 siege. Walking ST304 therefore connects you to a thread of history that runs the length of the country. Even as a single outing, though, it stands on its own: the contrast between the wild granite hills above Nadap and the royal coronation city at journey's end gives the day a satisfying narrative arc, from prehistoric rock to medieval kings.

Route Overview & Stages

The Nadap–Székesfehérvár leg is most naturally walked as one day, but it splits cleanly into three sections for planning, rest and resupply. Distances below are approximate and based on the on-the-ground waymarked corridor.

Cumulative figures across the day come to roughly 22 km with about 250 m of total ascent. There is no sustained climbing — the only real gradient is the early pull up out of Nadap into the Velence Hills, after which the route trends gently downhill toward the city. Underfoot you will find a mix of forest tracks, vineyard service roads and quiet rural lanes, with a few short rocky passages through the granite outcrops. Navigation is straightforward where the Sultans Trail waymarks are intact, but in the Velence Hills the route overlaps with several local Hungarian colour-blazed trails, so carrying a GPS track downloaded from the foundation's site is strongly recommended to avoid taking a wrong branch.

Highlights & Points of Interest

• Nadap benchmark stone — The historical zero-point of Hungary's national elevation network, set into the rock near the village; a quietly significant spot for anyone interested in geography.
• Meleg-hegy — At 352 m, the highest summit of the Velence Hills, offering open views north toward the Vértes mountains and south across Lake Velence.
• Velence Hills granite — Some of the oldest exposed granite in Hungary, weathered into rounded boulders and "rocking stones" scattered through the oak woods.
• Pákozd–Sukoró region — Close to the route, the site of the 1848 Battle of Pákozd, the first major battle of the Hungarian Revolution, now marked by a military memorial park.
• Pátka reservoir — A calm lake on the River Gaja, a popular angling and birdwatching spot passed on the descent toward the plain.
• Székesfehérvár Old Town — The medieval coronation city of Hungarian kings, with the Garden of Ruins (Romkert) marking the former royal basilica where 15 monarchs were crowned.
• Bory Castle — An eccentric early-20th-century castle on the edge of Székesfehérvár, hand-built over four decades by sculptor Jenő Bory.
• Lake Velence — One of Europe's warmest lakes, a short detour from Nadap, ringed with reed beds that draw migratory birds.
• Nadap village wine cellars — Small family presshouses set into the hillside, where local Velence-region whites can be tasted at the start of the walk.

Best Time to Hike the ST304 Nadap - Székesfehérvár

The Velence Hills sit in a warm, relatively dry pocket of central Hungary, which gives this stage a long comfortable season. The single best month is May: daytime highs sit around 20–24°C, the oak woodland is in fresh leaf, wildflowers cover the granite slopes, and the vineyards around Nadap are greening up. Crucially, May avoids both the muddy paths of late winter and the fierce heat that settles over the Pannonian plain in midsummer.

April and late September into October are the strong runners-up. Autumn brings grape harvest, golden oak colour and stable, cool walking weather — many regulars rate early October just behind May. July and August are walkable but uncomfortable; the open final stretch across the plain into Székesfehérvár offers little shade and temperatures regularly exceed 30°C. Start at dawn and carry extra water if you hike then.

Winter (December–February) is generally snow-free at these low elevations but can be grey, damp and muddy. As of 2026, Hungarian spring weather has trended warmer and slightly wetter, so a light rain layer is sensible even in the prime May window. Unlike the Bulgarian mountain sections of the wider Sultans Trail, this Hungarian leg is realistically hikeable year-round in dry spells.

Weekdays are noticeably quieter than weekends, when locals from Budapest descend on Lake Velence and the Velence Hills trails. If solitude matters to you, aim for a Tuesday-to-Thursday departure in the shoulder seasons. Daylight is also worth planning around: in May you have well over 15 hours of light, but by late October that drops below 11 hours, so an early start matters more in autumn to comfortably finish the 22 km before dusk.

Practical Information

Accommodation

Nadap and the surrounding Lake Velence villages (Sukoró, Velence, Pákozd) have a good spread of guesthouses (panzió) and private rooms, typically €35–60 per night for a double, reflecting the area's popularity as a domestic lakeside getaway. There is no formal mountain hut on this stage — the terrain is too low and settled for them. Wild camping is not permitted in Hungary outside designated sites, but campsites around Lake Velence charge roughly €10–18 per pitch in season.

Székesfehérvár, as a city of around 95,000 people, offers the full range: hostels from about €18–25 per dorm bed, mid-range hotels at €50–80, and several budget guesthouses. Booking ahead is wise during summer festivals and the grape harvest period.

Getting There & Back

Székesfehérvár is a major rail junction roughly 65 km southwest of Budapest, with frequent direct trains from Budapest-Déli and Kelenföld stations taking about 50–70 minutes. The nearest international airport is Budapest Ferenc Liszt (BUD), around 75 km away and reachable in about 1.5 hours by train via Budapest. To reach the Nadap start, take a regional train or bus toward the Lake Velence line and alight at Velence or Kápolnásnyék, then a short local connection or 30–40-minute walk up to Nadap. Check current schedules with the Hungarian State Railways before travelling: MÁV (Hungarian State Railways).

Permits & Fees

No permit or fee is required to walk the ST304 stage; the Sultans Trail and the Velence Hills paths are freely accessible public routes. There are no entry gates and no booking system. Some specific attractions charge admission — Bory Castle and certain museums in Székesfehérvár ask a few euros — but the trail itself is free. The Sultans Trail Foundation publishes route notes, GPS tracks and stamp-passport ("credential") information for the full Vienna–Istanbul journey at the official Sultans Trail website.

Gear & Packing List

This is a single long day on mostly good tracks and quiet lanes, so you can pack light. A 35–40 litre pack is plenty; the comfortable, lightweight Abisko Hike 35 or the technical Ascensionist 35L both suit a day with spare layers and food. If you are linking several Sultans Trail stages and carrying overnight kit, step up to a roomier ultralight option such as the 2400 Windrider — and if you are deciding what to carry it all in, our roundup of the best ultralight backpacks of 2026 compares seven tested packs.

Bring sturdy trail shoes (the granite sections can be loose), 2 litres of water minimum because reliable taps are sparse between villages, sun protection for the exposed plain, and a light rain shell. Trekking poles help on the early Velence Hills climb. Carry enough snacks for the day — the gap between Nadap and the Székesfehérvár outskirts has few shops. If you are planning energy for a full hiking day, see how many calories you need hiking a full day to size your food right.

Frequently Asked Questions

When is the best time to hike the ST304 Nadap–Székesfehérvár?
May is the single best month, with mild 20–24°C days, fresh oak woodland and wildflowers across the Velence Hills. April and early October are close behind, offering cool, stable conditions and autumn colour. Avoid midsummer if you can, as the shadeless final stretch across the plain regularly tops 30°C.

How difficult is this stage really?
The expert rating applies to the full 2,500-km Sultans Trail from Vienna to Istanbul, not this leg. On its own, the ~22 km Nadap–Székesfehérvár stage is moderate: roughly 250 m of gentle ascent on good tracks and lanes, with one short climb out of Nadap. Any reasonably fit walker comfortable with a long day can complete it.

How far is it and can it be done in one day?
The stage runs about 22 km point-to-point and is comfortably walked in a single day, taking most hikers 5–7 hours including breaks. It splits neatly into three sections of roughly 7–8 km each, so you can pace it around the Velence Hills ridge, the Pátka woodland edge, and the final approach into Székesfehérvár.

Where can I stay along the route?
Nadap and nearby Lake Velence villages have guesthouses at around €35–60 per double and campsites at €10–18 per pitch. Székesfehérvár, the destination, offers hostels from roughly €18–25 per dorm bed and hotels at €50–80. There are no mountain huts on this low-lying stage, so plan around village and city accommodation.

Do I need a permit or pay any fees?
No. The ST304 stage follows freely accessible public paths through the Velence Hills and into Székesfehérvár, with no permit, booking or trail fee required. Wild camping is restricted in Hungary, so use designated sites. Individual attractions such as Bory Castle charge small admission fees, but walking the trail itself costs nothing.
