ST710 Pazardzhik - Stambolijski

The ST710 Pazardzhik – Stambolijski is roughly an 18 km point-to-point stage of the Sultans Trail in Bulgaria's Maritsa Valley, near-flat with barely 30 m of elevation gain across a single day. It is rated expert only as part of the wider 2,500 km Vienna–Istanbul route, but this riverside section itself is a gentle lowland walk along the Maritsa.

About the ST710 Pazardzhik – Stambolijski

The ST710 is a numbered stage of the Sultans Trail, a 2,500 km long-distance hiking 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, Greece and Turkey — and traces the 1529 march of Sultan Süleyman the Magnificent, who left Istanbul on 10 May 1529 and reached the gates of Vienna 141 days later. Today the foundation behind the route promotes it as a path of peace and a meeting place for people of every faith and culture.

This particular segment belongs to the trail's alternative Bulgarian route, which runs through the Maritsa Valley via Plovdiv, Haskovo and Svilengrad rather than over the high Rila and Rhodope Mountains. Pazardzhik (population around 65,000) sits at roughly 205 m above sea level; Stambolijski, a small industrial town about 18 km east, sits near 190 m. Between them the trail follows agricultural lanes, river dikes and quiet roads alongside the Maritsa, Bulgaria's longest river. Because the elevation profile is almost flat, the ST710 is one of the most accessible stages on the entire Sultans Trail — a useful warm-up or wind-down day for thru-hikers tackling the larger network of the International Walking Network (IWN).

The Maritsa Valley has been a corridor of movement for millennia. The Romans built the Via Diagonalis (Via Militaris) through this basin to connect Belgrade with Constantinople, and Ottoman armies later used the same flat ground for their campaigns — the very history the Sultans Trail commemorates. Pazardzhik itself was founded in 1485 as an Ottoman market town, and its name derives from the Turkish for “little market.” Walking the ST710, you trace a route that has carried merchants, pilgrims and soldiers between Europe and Asia for more than two thousand years, which is part of what earned the wider trail its status as a Cultural Route of the Council of Europe.

The Sultans Trail is recognised as a Cultural Route of the Council of Europe and partly overlaps the European long-distance path E8. As a registered IWN route, it ranks among the world's most significant waymarked hiking corridors, which is why even a modest valley stage like the ST710 carries a formal stage number and waymarking.

Route Overview & Stages

The ST710 is most easily understood as three rolling sub-sections between the two towns. Distances below are approximate, as the foundation reroutes around seasonal farm tracks and flood works.

Total walking time is roughly 4 to 5 hours at a steady 4 km/h pace, with no technical sections. The trail is well within reach of anyone who has logged a few comfortable lowland day-hikes, despite the network-wide expert rating. Surfaces alternate between compacted gravel on the flood dike, asphalt through villages and dirt farm tracks, so trail-runners or light hiking shoes are more comfortable than heavy boots. The only navigational care points are the urban exit from Pazardzhik and the farmland approach to Stambolijski, where Sultans Trail waymarks — a stylised tulip-and-crescent symbol — thin out and a GPX track keeps you on line.

Highlights & Points of Interest

• Holy Mother of God Cathedral, Pazardzhik — an 1837 Orthodox church famous for its hand-carved walnut iconostasis, one of the finest examples of the Bulgarian National Revival woodcarving school.
• Pazardzhik central square — the trail leaves town past the Stoyan and Vesa Vaptsarov museum and a lively daily market, a good place to stock food before the riverside stretch.
• Maritsa River dike — the spine of the stage, a raised flood embankment that gives long, open views over the river and the distant Rhodope foothills to the south.
• Poplar and willow galleries — shaded riverine woodland that shelters herons, cormorants and, in spring, returning storks nesting on village poles.
• Ognyanovo turnoff — a small spa-village junction known regionally for thermal mineral springs, a worthwhile short detour for a soak.
• Maritsa Valley farmland — rice paddies, vineyards and vegetable fields that make this one of Bulgaria's most productive agricultural belts.
• Stambolijski paper mill — the landmark that gives the town its industrial skyline; the trail skirts its edge before reaching the centre.
• Stambolijski railway station — the practical end point of the stage, on the Plovdiv–Sofia main line with frequent regional trains.

Best Time to Hike the ST710 Pazardzhik – Stambolijski

The Maritsa Valley has a transitional climate that swings from hot summers to chilly, damp winters. May is the single best month to walk the ST710: daytime highs sit around 22–25 °C, the river runs full and clear after the snowmelt, fruit trees and wildflowers are in bloom, and the farm tracks are dry but not yet dusty. As of 2026 the foundation continues to recommend spring and autumn for the Bulgarian lowland stages over the high mountain alternatives.

April and June are strong runners-up — April can be showery, while late June starts to feel hot. September and early October bring a second window with grape and vegetable harvests, stable weather and highs near 24 °C. Avoid July and August, when valley temperatures regularly exceed 35 °C and the open dike offers little shade, and December to February, when fog, frost and occasional Maritsa flooding can make the riverbank muddy and bleak. Whatever the month, start early to bank the cooler morning hours and carry sun protection for the exposed embankment. Spring also coincides with the stork migration, when dozens of white storks nest on village poles along the route — a highlight that disappears by late summer. After heavy spring rain the Maritsa can rise quickly, so check local conditions if you plan to walk close to the water rather than on the raised dike.

Practical Information

Accommodation

Both ends of the stage have beds, so you do not need to camp. In Pazardzhik, family-run guesthouses and small hotels run roughly €25–45 per night for a double room, with a couple of mid-range business hotels nearer €50–65. Stambolijski is smaller; expect one or two modest guesthouses around €25–40, and many hikers simply continue 12 km by train to Plovdiv, where hostels start near €12–18 per dorm bed and well-reviewed boutique hotels run €45–80. Wild camping is tolerated discreetly along the river for thru-hikers, but the foundation only recommends tents for the high mountain sections, not this valley stage.

Getting There & Back

Pazardzhik sits on the main Sofia–Plovdiv–Burgas railway. From Sofia Central Station, regional and fast trains reach Pazardzhik in about 1 hour 30 minutes to 2 hours for roughly €5–8. From Plovdiv, the journey is about 25–35 minutes. The nearest major airport is Plovdiv Airport (PDV), around 40 km east, though it has limited seasonal service; Sofia Airport (SOF), about 120 km west and roughly 2 hours by train plus metro, is the reliable international gateway. At the finish, Stambolijski station sits on the same line, with frequent trains back to Pazardzhik (about 12 minutes) or onward to Plovdiv (about 20 minutes), making a logistics-free day trip easy. Check the Bulgarian State Railways (BDŽ) timetable before you travel, as regional frequencies change seasonally.

Permits & Fees

No permit or entry fee is required to walk the ST710. The Sultans Trail is a free, volunteer-maintained public route; the only costs are transport, food and lodging. The foundation appreciates donations and sells GPX tracks and guidebooks to fund waymarking — details are on the official Sultans Trail website. Bulgaria is in the EU and the Schengen area as of 2026, so most European visitors need no special documentation; non-EU hikers should check standard short-stay visa rules.

Gear & Packing List

This is a warm-weather lowland day-hike, so pack light. A 20–40 litre daypack is plenty — the Salomon ADV Skin 20 is ideal for a fast, fastpacking-style single day, while the Fjällräven Abisko Hike 35 suits hikers who prefer a structured back panel and room for layers. If you are linking the ST710 into a multi-day Sultans Trail push, a larger ultralight pack such as the Hyperlite Mountain Gear 2400 Windrider keeps the load comfortable over consecutive valley stages. For more options, see our roundup of the best ultralight backpacks of 2026.

Beyond the pack, prioritise: 2–3 litres of water (springs are unreliable on the dike), a sun hat and SPF for the shadeless embankment, sturdy trail shoes (no boots needed on flat ground), a light rain shell for spring showers, and a power bank for navigation. Waymarking on the Bulgarian alternative route can be sparse, so download an offline GPX track and carry a phone or GPS.

Similar Trails You Might Like

If the lowland, long-distance character of the ST710 appeals, Bulgaria offers two major European trails that cross similar terrain and connect to the same network. Both run through the country and share waymarking philosophy with the Sultans Trail, and both can be combined with valley stages for a longer itinerary.

• Европейски пешеходен маршрут Е4, България — the Bulgarian section of the long E4, climbing from the Rila and Pirin ranges down toward the Aegean.
• European long distance path E8 - part Bulgaria — the E8 corridor that the Sultans Trail itself partly follows across Bulgaria.

Frequently Asked Questions

When is the best time to hike the ST710 Pazardzhik – Stambolijski?
May is the best month, with daytime highs around 22–25 °C, a full clear Maritsa River and blooming valley vegetation. April, June, September and early October also work well. Avoid July and August, when valley temperatures top 35 °C with little shade, and the foggy, flood-prone winter months from December to February.

How hard is the ST710 stage?
Despite the expert rating that applies to the full 2,500 km Sultans Trail, this stage itself is easy. It covers about 18 km of near-flat ground with only around 30 m of total elevation gain and no technical terrain. Any reasonably fit walker can complete it in 4–5 hours; the main challenge is sun exposure on the open river dike.

How far is each day on this section?
The ST710 is designed as a single day of roughly 18 km between Pazardzhik and Stambolijski. Most hikers walk it in one go in about 4 to 5 hours at a steady 4 km/h pace. You can shorten it by starting from the Maritsa dike or extending it by linking adjacent Sultans Trail stages toward Plovdiv for a multi-day valley itinerary.

Where can I stay along the route?
Both towns have beds, so camping is not needed. Pazardzhik guesthouses and small hotels run about €25–65 per night, and Stambolijski has modest guesthouses near €25–40. Many hikers ride the train 12 km on to Plovdiv, where hostel dorms start near €12–18 and hotels range €45–80, giving more choice and dining options.

Do I need a permit or pay a fee?
No. The Sultans Trail is a free, volunteer-maintained public route, and the ST710 requires no permit or entry fee. Your only costs are transport, food and accommodation. The foundation funds waymarking through optional donations and sells GPX tracks and guidebooks. EU visitors need no special paperwork; non-EU hikers should check standard Schengen short-stay rules for 2026.
