ST709 Septemvri - Pazardzhik

The ST709 Septemvri - Pazardzhik is an approximately 18 km point-to-point trail in the Maritsa Valley of southern Bulgaria, gaining only about 60 m of elevation across a single flat valley day. Rated expert because it forms one link in the 2,500 km Sultans Trail from Vienna to Istanbul, it rewards walkers with Thracian plain, riverside villages and a deep cultural backstory.

About the ST709 Septemvri - Pazardzhik

The ST709 Septemvri - Pazardzhik is a waymarked stage of the Sultans Trail, the 2,500 km cultural walking route that runs from St. Stephen's Cathedral in Vienna to the Süleymaniye Mosque in Istanbul, crossing nine countries along the way. This particular segment sits in Bulgaria's Upper Thracian Plain, linking the railway town of Septemvri with the provincial capital of Pazardzhik, roughly 18 km to the east. Both towns lie on the banks of the Maritsa, the longest river running solely through the interior of the Balkans, and the trail traces the gentle agricultural corridor between them.

The Sultans Trail commemorates the 1529 campaign of Sultan Süleyman the Magnificent, who left Istanbul on 10 May 1529 and reached Vienna 141 days later on 23 September. Developed by volunteers of a Netherlands-based NGO, the modern route is presented as a path of peace and a meeting place for people of all faiths and cultures. The ST709 belongs to the Maritsa Valley variant of the Bulgarian section, an alternative to the main mountain route through the Rila and Rhodope ranges, and it follows portions of the E8 European long-distance path. The International Walking Network (IWN) classification places it among the world's most significant signed hiking corridors.

Physically the day is undemanding — flat farmland, dirt tracks and quiet asphalt — but the "expert" rating reflects its role inside a continental thru-hike where navigation, self-sufficiency and stamina across many consecutive days matter far more than any single climb. Walked on its own, it is an easy half-day; walked as part of the Sultans Trail, it is one careful step in a months-long undertaking.

Route Overview & Stages

The ST709 is itself a single Sultans Trail stage, but most walkers fold it into the wider Maritsa Valley sequence. The table below shows the ST709 alongside the adjacent stages that frame it, so you can see how a multi-day plan fits together. Distances are approximate and based on the valley alignment.

For walkers tackling only the ST709, the 18 km can comfortably be completed in 4 to 5 hours of steady walking. Those continuing east usually split the longer Pazardzhik to Plovdiv leg over a night's rest, since 38 km of flat trail in summer heat is more tiring than the profile suggests.

Highlights & Points of Interest

• Septemvri railway terminus — the eastern end of the famous 760 mm narrow-gauge Septemvri–Dobrinishte line, the only surviving narrow-gauge railway in Bulgaria and a fitting place to begin the day.
• Varvara — a small Maritsa-side village a few kilometres east of Septemvri, with a parish church and shaded squares useful for a first water stop.
• The Maritsa river bank — the trail follows the broad, slow river for long stretches, with poplar windbreaks and birdlife typical of the Thracian lowlands.
• Irrigation canals and farmland — the Upper Thracian Plain is Bulgaria's market garden; expect tomato fields, vineyards and orchards lining the path through summer.
• Pazardzhik Holy Mother of God Cathedral — an 1837 Revival-era church famous for its carved walnut iconostasis, one of the finest examples of Bulgarian woodcarving.
• Pazardzhik old town and Stanislav Dospevski House — 19th-century National Revival architecture and the museum-home of the noted Bulgarian painter.
• Maritsa pedestrian bridges in Pazardzhik — riverside parkland marking the natural end of the stage, with cafes and benches for tired feet.
• Ottoman-era heritage — Pazardzhik was founded in the 15th century as an Ottoman market town (its name means "little market"), tying the day directly to the Sultans Trail theme.

Best Time to Hike the ST709 Septemvri - Pazardzhik

The Maritsa Valley has a warm continental climate, and the lowland setting makes timing about heat and daylight rather than snow. The single best month is May: average daytime highs sit around 22–25 C, the plain is green, the river runs full from snowmelt, and long evenings give plenty of margin for the 18 km. April and the first half of June are nearly as good.

Midsummer is the season to avoid. In July and August the Thracian Plain regularly exceeds 33–36 C with little shade across the open farmland, and the 2026 outlook continues the recent trend of hot, dry Balkan summers — start before 07:00 and carry extra water if you walk then. Autumn reopens the trail beautifully: September and October bring 18–26 C, grape harvest in the surrounding vineyards and stable, dry tracks. Winter walking is possible since the valley rarely holds deep snow, but short daylight, muddy field paths after rain and grey skies make November to February the least rewarding window. If you want one date to plan around in 2026, aim for mid-May.

Practical Information

Accommodation

Because the ST709 starts and finishes in towns, there is no need to camp. In Septemvri a handful of small guesthouses and family hotels charge roughly €20–35 for a double room. Pazardzhik, as a provincial capital of around 65,000 people, has more choice — town-centre hotels and guesthouses typically run €30–55 per night, with budget rooms occasionally below €25. Wild or informal tent camping is tolerated in parts of rural Bulgaria along the Sultans Trail, and a riverside pitch outside the villages is feasible, but facilities are minimal and you should ask landowners where possible. Plan your daily food load before setting out — our guide on how many calories you need hiking a full day helps you pack the right amount without overloading.

Getting There & Back

Both ends of the stage sit on the Sofia–Plovdiv main railway line, which makes the ST709 unusually easy to reach. Septemvri has a staffed station served by frequent regional and fast trains; the journey from Sofia takes about 1 hour 30 minutes, and from Plovdiv about 40 minutes. Pazardzhik station is one stop east, around 15 minutes by train from Septemvri, so you can walk the trail in one direction and ride straight back to your start — ideal for a day hike. The nearest major airport is Plovdiv (PDV), roughly 50 minutes east by road or rail, while Sofia Airport (SOF), about 2 hours away, offers far more international connections. Check current timetables with the national operator Bulgarian State Railways (BDZ) before travelling.

Permits & Fees

No permit, fee or registration is required to walk the ST709 or any other section of the Sultans Trail in Bulgaria. The route runs on public roads, field tracks and riverside paths, all freely accessible. The only costs are accommodation, food and transport. Museums in Pazardzhik charge modest entry fees of around €2–4. For route updates, GPX downloads and waymarking notes, consult the official Sultans Trail website, which the volunteer organisation maintains for the whole Vienna–Istanbul corridor as of 2026.

Gear & Packing List

For a lowland day stage like the ST709, your kit can be light. The terrain is flat and the surfaces forgiving, so trail runners or light hiking shoes beat heavy boots. Sun protection is the real priority on the exposed Thracian Plain — a brimmed hat, sunglasses and at least 2 litres of water capacity per person. Pack a light rain shell for spring and autumn showers, snacks, and a small first-aid kit.

A pack in the 20–40 litre range is ample. For a fast day-hike the Salomon ADV Skin 20 running vest carries water and layers close to the body. If you are linking several Sultans Trail stages and carrying camping kit, a frame pack such as the Osprey Aether 65 or the ultralight Hyperlite Mountain Gear 2400 Windrider handles multi-day loads while keeping weight down.

Frequently Asked Questions

When is the best time to hike the ST709 Septemvri - Pazardzhik?
Mid-May is the single best window. Daytime highs of 22–25 C, a full-flowing Maritsa and long daylight make the 18 km comfortable. April, early June, September and October are also excellent. Avoid July and August, when the open Thracian Plain regularly tops 33 C with almost no shade.

How difficult is the ST709 Septemvri - Pazardzhik?
On its own the stage is easy: about 18 km of flat farmland and riverside path with only ~60 m of climbing. The expert rating reflects its place inside the 2,500 km Sultans Trail, where self-sufficiency, navigation and stamina over many consecutive days matter far more than this single, gentle valley section.

How long is the ST709 and how many kilometres per day?
The ST709 covers roughly 18 km between Septemvri and Pazardzhik, walkable in 4 to 5 hours, so it is comfortably a single day. Thru-hikers continuing the Maritsa Valley route typically average 18–30 km per day, splitting the longer 38 km Pazardzhik–Plovdiv leg with an overnight stop.

Where can I stay along the ST709 Septemvri - Pazardzhik?
Both towns have accommodation, so camping is optional. Septemvri guesthouses cost about €20–35 a night, while Pazardzhik hotels and guesthouses run roughly €30–55. Informal riverside tent camping is tolerated in rural stretches, but facilities are minimal, so booking a town room is the simpler choice for most walkers.

Do I need a permit or fee to walk the ST709?
No. The Sultans Trail through Bulgaria, including the ST709, needs no permit, fee or registration. It follows public roads, field tracks and riverside paths that are freely accessible year-round. Your only costs are accommodation, food, transport and optional museum entries of around €2–4 in Pazardzhik.
