ST13 Bruck an der Leitha - Petronell Carnuntum

The ST13 Bruck an der Leitha – Petronell-Carnuntum is an approximately 16 km point-to-point walking stage in Lower Austria, part of the 2,500 km Sultans Trail from Vienna to Istanbul. It gains only about 120 m of elevation across gentle Danube-plain terrain, yet carries an expert grading for its length, navigation demands and exposure, ending at Europe’s great Roman city of Carnuntum.

About the ST13 Bruck an der Leitha - Petronell Carnuntum

The ST13 is the thirteenth numbered 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 crosses nine countries — Austria, Slovakia, Hungary, Croatia, Serbia, Bulgaria, North Macedonia, Greece and Turkey — and is maintained by the Sultans Trail Foundation, a Netherlands-based cultural-route organisation. The whole path is classed within the International Walking Network (IWN), one of the most significant waymarked hiking systems in the world.

This particular stage runs roughly 16 km from the market town of Bruck an der Leitha, on the Leitha river that historically divided Austria from Hungary, north-east across the open Pannonian lowlands to Petronell-Carnuntum, the modern village built over one of the largest Roman settlements north of the Alps. The route follows the historical line of Sultan Süleyman the Magnificent’s 1529 campaign toward Vienna, which the Sultans Trail commemorates as a “path of peace.”

Although the terrain is flat and the cumulative climb is small — around 120 m — the stage is rated expert. The grading reflects the distance walked in a single day, long exposed sections without shade or shelter, river-meadow paths that can flood, and the navigational care needed where the waymarking thins between villages. Walkers should be comfortable reading a route and managing their own water and pacing. If you are planning long, self-sufficient days, our guide on how many calories you need hiking a full day is worth reading before you set out.

Route Overview & Stages

The ST13 can be walked as one continuous day or split at the halfway hamlets near Höflein and Petronell. The table below breaks the stage into its three natural sections.

Total walking time runs about 4 to 5 hours at a steady pace, plus whatever time you give to the Roman sites at the finish — easily a half-day on their own.

Highlights & Points of Interest

• Bruck an der Leitha castle (Schloss Prügenhof) — a Baroque palace and landscaped park at the start, marking the former Austria-Hungary border on the Leitha.
• Leitha river crossing — the gentle waterway whose name historically separated Cisleithania from Transleithania in the Habsburg monarchy.
• Prellenkirchen vineyards — sun-facing slopes producing the dry whites typical of the Carnuntum wine region.
• Heidentor (Pagan Gate) — the surviving pillar of a 4th-century Roman triumphal monument, the symbol of Carnuntum, standing alone in a field outside Petronell.
• Carnuntum amphitheatre — one of two arenas at the site, once seating around 8,000 spectators; the military amphitheatre lies near the legionary fortress.
• Römerstadt Carnuntum open-air museum — fully reconstructed Roman townhouses, baths and a heated villa where you can walk through buildings rebuilt with original techniques.
• Danube floodplain (Donau-Auen) — the protected riverside wetlands bordering the route to the north, part of a national park.
• Petronell parish church — a Romanesque round chapel (Rundkapelle) dating from the 12th century in the village centre.

Best Time to Hike the ST13 Bruck an der Leitha - Petronell Carnuntum

The Pannonian basin around Carnuntum is one of the warmest and driest corners of Austria, which shapes the ideal walking window. The Sultans Trail Foundation notes the route is broadly walkable year-round outside the high Bulgarian mountains, and this lowland Austrian stage holds true to that — but comfort varies sharply by season.

Late April through early June is the prime window. Spring brings green farmland, manageable temperatures of 15–22°C, and long daylight, while the exposed fields are not yet baked. May is the single best month to walk the ST13: the Carnuntum vineyards are in leaf, wildflowers line the field tracks, rainfall is moderate, and the Roman park is open without peak-summer crowds.

July and August can exceed 33°C on this shadeless terrain, making the open middle section punishing — start at dawn if you walk in high summer and carry extra water. September and early October offer a fine second window, with the grape harvest and cooler, stable air. As of 2026, the Römerstadt Carnuntum archaeological park typically opens from mid-March to mid-November, so winter walkers will find the finish-line museums closed even though the path itself stays passable. Check current opening dates before you travel.

Practical Information

Accommodation

This is a populated lowland corridor, so beds are easy to find. In Bruck an der Leitha, guesthouses (Gasthof) and small hotels run roughly €60–100 per double room with breakfast. Petronell-Carnuntum and neighbouring Bad Deutsch-Altenburg offer pensions and wine-estate rooms from about €55–90. The Sultans Trail tradition favours simple private rooms and family guesthouses over huts; there are no mountain refuges on this stage. Campers will find a riverside site at Bad Deutsch-Altenburg charging around €10–15 per person per night. Hostel-style dormitory beds are limited locally, so booking ahead in May and September is wise.

Getting There & Back

Both endpoints sit on the Austrian rail network, which makes the ST13 unusually easy to reach. Bruck an der Leitha has its own station on the line toward Hungary, about 35–45 minutes from Vienna Hauptbahnhof. Petronell-Carnuntum station sits on the regional S-Bahn line along the Danube and returns you to Vienna in roughly 50–60 minutes. The nearest major airport is Vienna International Airport (VIE) at Schwechat, about 25 km west, from which both towns are reachable by train within an hour. You can plan the linear logistics — train out, walk, train back — inside our hike planner. For full Austrian timetables and fares, consult the national operator at ÖBB.

Permits & Fees

No permit is required to walk the ST13; the trail is free and open public right-of-way along field tracks, minor roads and riverside paths. The only fees are for the Roman attractions at the finish: a combined ticket to the Römerstadt Carnuntum sites (open-air city, Heidentor area and amphitheatres) costs around €13–15 for adults, with reductions for students and families. Opening hours and current ticket prices are published by the operator at Carnuntum Archaeological Park.

Gear & Packing List

Because the ST13 is flat but long and exposed, pack for sun and distance rather than altitude. A comfortable daypack of 20–35 litres is ideal — lightweight options like the Hyperlite Mountain Gear 2400 Windrider or the structured Fjällräven Abisko Hike 35 both carry a day’s water and layers easily. For fast-and-light walkers wanting minimal weight on a single long push, the Salomon ADV Skin 12 running vest holds soft flasks within reach for the shadeless central section. Beyond the pack, prioritise: at least 2 litres of water capacity, a sun hat and high-SPF cream, trail shoes (no boots needed on this flat ground), a light wind shell for open fields, and snacks for a 4–5 hour day.

Similar Trails You Might Like

If the cultural-history character of the ST13 appeals, you may enjoy other Austrian long-distance routes — though most contrast sharply with this lowland stage by climbing into the Alps. For high-mountain scenery, the Stubaier Höhenweg, the Berliner Höhenweg Zustieg Ahornbahn and the famous Adlerweg trade flat farmland for ridgelines and refuges. For more long-distance, multi-week endeavours in the same vein as the Sultans Trail, the cross-country routes JK01 and JK02 — each around 720 km — offer comparable sustained walking commitment.

Frequently Asked Questions

When is the best time to hike the ST13?
May is the best month. Spring temperatures of 15–22°C, green vineyards and moderate rainfall make for comfortable walking, and the Carnuntum Roman park is open without summer crowds. Late April to early June and September are both excellent. Avoid July and August midday heat, which regularly tops 33°C on this shadeless lowland terrain.

How difficult is the ST13 stage?
It is rated expert despite being almost flat, gaining only about 120 m. The grading reflects the roughly 16 km distance walked in one day, long exposed sections without shade, occasionally flooded river-meadow paths, and waymarking that thins between villages. Fitness demands are moderate, but self-sufficiency with water, pacing and navigation is essential.

How far is the ST13 per day?
The full stage covers about 16 km from Bruck an der Leitha to Petronell-Carnuntum, taking 4 to 5 hours of walking. Most people do it as a single day. It can be split near Höflein for a gentler two-half itinerary, leaving extra time to explore the Roman archaeological park at the Carnuntum finish.

What accommodation is available along the route?
Guesthouses and small hotels in Bruck an der Leitha cost roughly €60–100 per double with breakfast, while pensions and wine-estate rooms in Petronell-Carnuntum and Bad Deutsch-Altenburg run €55–90. A riverside campsite at Bad Deutsch-Altenburg charges around €10–15 per person. There are no mountain huts; book ahead in May and September.

Do I need a permit to walk the ST13?
No permit is required. The trail follows free public paths, field tracks and minor roads, open year-round. The only costs are optional admission to the Carnuntum Roman sites at the finish — a combined adult ticket is around €13–15, with student and family discounts — and any train fares to and from Vienna, about an hour away.
