ST711 Stambolijski - Plovdiv

The ST711 Stamboliyski–Plovdiv is a roughly 25-km point-to-point trail in the Maritsa Valley of south-central Bulgaria, gaining only about 60 m of elevation across one easy walking day. Despite its flat profile, it carries an expert rating for navigation, as it forms one waymarked stage of the 2,500-km Sultans Trail running from Vienna to Istanbul.

About the ST711 Stamboliyski - Plovdiv

The ST711 is a single stage on the alternative Maritsa Valley route of the Sultans Trail, a 2,500-kilometre cultural long-distance path that links St. Stephen's Cathedral in Vienna with the Süleymaniye Mosque complex in Istanbul. The full trail passes through eight countries — Austria, Slovakia, Hungary, Croatia, Serbia, Bulgaria, the Greek region of East Macedonia and Thrace, and Turkey — and commemorates the 1529 campaign of Sultan Süleyman the Magnificent, who marched from Istanbul to Vienna in 141 days. Today the route is promoted as a path of peace and a meeting place for people of all faiths and cultures.

This particular stage runs eastward from the small industrial town of Stamboliyski to Plovdiv, Bulgaria's second-largest city and one of the oldest continuously inhabited settlements in Europe. The walking is almost entirely flat, following the broad floodplain of the Maritsa River, the longest river running solely through the interior of the Balkans. While the gradient is gentle, the "expert" classification reflects the practical realities of the corridor: waymarking on the Maritsa Valley variant is sparse, the route threads through farmland, irrigation channels, village lanes and the urban fringe of Plovdiv, and hikers must be comfortable with self-navigation using a GPX track. The Sultans Trail Foundation, the Netherlands-based volunteer NGO that develops and maintains the route, marks the path with hiking stickers rather than continuous painted blazes.

For most walkers the ST711 is best understood as a connector stage — a low, cultural, river-valley day rather than a mountain challenge. It rewards those interested in Ottoman and Roman heritage, Thracian history and the everyday rhythm of the Bulgarian plain, finishing in a city packed with antiquities. The Sultans Trail here also overlaps in spirit with the European long distance path E8 - part Bulgaria, of which the wider Sultans Trail follows sections.

Plovdiv itself anchors the stage's appeal. Built across six syenite hills and inhabited for some 8,000 years, the city was the Thracian Eumolpias, the Roman Philippopolis and an important Ottoman centre in turn — layers of history that mirror the Sultans Trail's own cross-cultural mission. Reaching it on foot from the quiet plain, rather than arriving by car or train, gives the ST711 a sense of pilgrimage that suits a route founded as a path of peace between faiths and cultures.

Route Overview & Stages

The ST711 is a one-day stage, but it sits between neighbouring Sultans Trail segments on the Maritsa Valley alternative. The table below shows the ST711 in context, with approximate figures for the adjoining sections so you can plan a multi-day itinerary along the river corridor.

Distances on the Maritsa Valley variant are approximate, as the Sultans Trail Foundation refines the route over time and walkers often improvise around closed farm tracks. Treat the ~25 km for the ST711 as a realistic planning figure for a flat, full walking day of roughly six to seven hours including breaks.

Highlights & Points of Interest

• Stamboliyski town centre — the starting point, a paper-industry town named after agrarian statesman Aleksandar Stamboliyski; a practical place to stock up before the river walk.
• Maritsa River floodplain — the trail's defining feature, a wide braided river valley with poplar galleries, willow thickets and abundant birdlife including herons and storks.
• Tsaratsovo and plain villages — small agricultural settlements west of Plovdiv where you pass orchards, vineyards and Orthodox village churches typical of the Thracian plain.
• Komatevo / western Plovdiv outskirts — the gradual transition from farmland to suburb that signals the approach to the city.
• Dzhumaya Mosque, Plovdiv — a 15th-century Ottoman mosque on the central square, a fitting Sultans Trail landmark tied to the route's Ottoman heritage theme.
• Roman Theatre of Philippopolis — a remarkably preserved 2nd-century amphitheatre seating around 5,000 spectators, perched above the Old Town.
• Plovdiv Old Town (Stariyat grad) — cobbled streets lined with colourful 19th-century National Revival houses, museums and the Nebet Tepe Thracian fortress ruins.
• Kapana creative district — a regenerated grid of artisan workshops, cafés and galleries, the best place to refuel at journey's end.

Best Time to Hike the ST711 Stamboliyski - Plovdiv

Unlike the mountainous Rila and Rhodope sections of the Sultans Trail, the Maritsa Valley is walkable for most of the year because it sits low on the plain at around 160–170 m above sea level. That said, the season makes a real difference to comfort. As of 2026, the recommended windows are April to early June and mid-September to October, when daytime temperatures sit in a pleasant 18–25 °C range and the riverside vegetation is green rather than parched.

The single best month is May: wildflowers cover the plain, the Maritsa runs full from snowmelt, daylight is long, and the summer heat has not yet arrived. July and August are the months to avoid — the Thracian plain regularly exceeds 35 °C, there is little continuous shade across the open farmland, and the river level drops. Winter walking is possible thanks to the low elevation, but the valley can be foggy, muddy and cold, and fields turn to heavy mud after rain. If you are tackling the wider Sultans Trail end-to-end, schedule the Bulgarian lowland stages like the ST711 in spring or autumn and save the mountain stages for the brief alpine window.

Practical Information

Accommodation

Because the ST711 begins and ends in towns, you are never far from a bed. In Stamboliyski, simple guesthouses and small hotels run roughly €25–40 per night for a double room. Plovdiv offers the full range: hostel dorm beds from around €12–18, mid-range guesthouses and boutique hotels in the Old Town at €40–80, and budget rooms near the bus and train stations from about €25. Wild camping is technically restricted in Bulgaria but tolerated discreetly outside settlements, and the Sultans Trail Foundation notes that tenting is recommended for parts of the Bulgarian route where formal lodging is thin. There are no mountain huts on this lowland stage, so plan to sleep in town at either end.

Getting There & Back

The stage is unusually easy to reach for a long-distance trail. Plovdiv International Airport (PDV) lies about 12 km southeast of the city, while Sofia Airport (SOF) — 150 km away and roughly 1.5–2 hours by road or rail — offers far more international connections. Both Stamboliyski and Plovdiv sit on the Sofia–Plovdiv railway line; the train between them takes only about 20–30 minutes, so you can stay in Plovdiv and ride out to Stamboliyski to start walking. Frequent intercity buses also link Plovdiv with Sofia in around two hours. This rail link makes the ST711 ideal as a self-contained day hike with a simple train return.

Permits & Fees

No permit or fee is required to walk the ST711 or any part of the Sultans Trail in Bulgaria — the route follows public roads, tracks and rights of way. The trail is free to hike year-round. Entry charges apply only to specific attractions in Plovdiv, such as the Roman Theatre and Old Town museum houses, which typically cost a few euros each. Check the official Sultans Trail website for the latest GPX tracks and route updates before you set out, and consult the Bulgarian National Radio English service for regional news and seasonal travel advisories.

Gear & Packing List

The ST711 is a low, warm, single-day walk, so your kit can be light. The priorities are sun protection, plenty of water capacity for the shadeless plain, and footwear suited to flat tracks and tarmac rather than alpine boots. A compact daypack is more than enough for this stage; a 35-litre pack such as the Abisko Hike 35 comfortably carries a day's food, water and a layer. If you are walking the ST711 as one leg of a multi-day Sultans Trail traverse and carrying camping gear, step up to a larger ultralight pack like the 2400 Windrider or, for heavier loads, the Arc Haul Ultra 60L. For choosing between models, our roundup of the best ultralight backpacks of 2026 compares seven packs tested side by side.

Pack a wide-brimmed hat, sunscreen, at least two litres of water capacity, and trail snacks — the open farmland gives you few resupply points until you reach the Plovdiv suburbs. Because this is a flat valley day, calorie needs are lower than on mountain stages; our guide to how many calories you need hiking a full day helps you size your food. Lightweight trail shoes outperform stiff boots on the tarmac and gravel of the Maritsa corridor. A simple rain shell is worth carrying in spring and autumn, when valley showers move through quickly, and trekking poles are optional given the negligible elevation change. Because resupply is limited until the Plovdiv suburbs, pack enough water and snacks to be self-sufficient for the full ~25 km, and download the official GPX track to your phone with offline maps before leaving Stamboliyski, since the sticker waymarking cannot be relied on at every junction.

Frequently Asked Questions

When is the best time to hike the ST711 Stamboliyski–Plovdiv?
May is the single best month. Spring (April to early June) and autumn (mid-September to October) both offer comfortable 18–25 °C temperatures and green riverside scenery. Avoid July and August, when the open Thracian plain regularly tops 35 °C with little shade. The low elevation keeps the stage walkable in winter, though fog and mud are common.

How difficult is the ST711, and why is it rated expert?
Physically the stage is easy — about 25 km of flat walking with only ~60 m of elevation gain. The expert rating reflects navigation rather than terrain: the Maritsa Valley variant of the Sultans Trail is sparsely waymarked with stickers, crosses farmland and urban edges, and requires confident self-navigation using a downloaded GPX track and offline maps.

How far is the walk and can I do it in one day?
The ST711 is roughly 25 km from Stamboliyski to central Plovdiv. Because it is almost entirely flat, most walkers complete it in six to seven hours including breaks, making it a comfortable single day. A short 20–30 minute train ride links the two towns, so you can base yourself in Plovdiv and ride out to the start.

Where can I sleep along this stage?
You sleep in town at either end rather than in huts. Stamboliyski has guesthouses around €25–40 per night, while Plovdiv offers everything from €12–18 hostel dorms to €40–80 Old Town hotels. There are no mountain refuges on this lowland section; the Sultans Trail Foundation recommends carrying a tent only for thinner-served stretches of the wider Bulgarian route.

Do I need a permit or pay a fee to hike the ST711?
No. The Sultans Trail follows public roads, tracks and rights of way through Bulgaria, so walking the ST711 is free and requires no permit or registration at any time of year. The only charges you may encounter are small entry fees for Plovdiv attractions such as the Roman Theatre and the National Revival museum houses in the Old Town.
