ST720 Lyubimets-Svilengrad

The ST720 Lyubimets-Svilengrad is a roughly 20 km point-to-point trail in the Maritsa Valley of southeastern Bulgaria, gaining around 250 m of cumulative elevation across a single day of walking. Rated expert for its long exposed stretches, navigation demands and lack of services, it forms one of the final Bulgarian stages of the 2,500 km Sultans Trail running from Vienna to Istanbul.

About the ST720 Lyubimets-Svilengrad

The ST720 Lyubimets-Svilengrad is a stage on the Sultans Trail, a 2,500-kilometre cultural long-distance route that connects St. Stephen's Cathedral in Vienna with the Süleymaniye Mosque in Istanbul. The trail commemorates the 1529 campaign of Sultan Süleyman the Magnificent, who left Istanbul on 10 May 1529 and reached the gates of Vienna 141 days later. Today the path is promoted as a route of peace crossing eight countries — Austria, Slovakia, Hungary, Croatia, Serbia, Bulgaria, Greece and Turkey — and it overlaps with the European long-distance path E8 for much of its course.

This particular stage belongs to the Maritsa Valley variant, an alternative southern line that runs through Plovdiv, Haskovo, Harmanli, Lyubimets and Svilengrad before crossing into Turkey. Where the main route climbs through the Rila and Rhodope mountains, the Maritsa option follows the broad, fertile river corridor that has carried armies, traders and pilgrims between Europe and Asia Minor for more than two thousand years. Lyubimets and Svilengrad sit close to the point where Bulgaria, Greece and Turkey meet, making this one of the most geopolitically storied corners of the whole walk.

As a part of the International Walking Network (IWN), the Sultans Trail is registered among the world's most significant signed hiking routes, and the Lyubimets-Svilengrad leg is way-marked along its length. Despite the gentle terrain on paper, the stage earns its expert rating: summer heat in Thrace is fierce, shade is scarce, water sources between settlements are unreliable, and several connecting tracks cross open farmland where the waymarking thins out and a GPX file becomes essential. Hikers comfortable on mountain paths can still find this lowland stage surprisingly testing.

What makes the ST720 worth the effort is the depth of history packed into a short corridor. The Maritsa Valley — known to the ancient Greeks as the Hebrus — has been a continental crossroads since Thracian times, and successive Roman, Byzantine and Ottoman powers all built roads, bridges and fortresses along it. Walking from Lyubimets to Svilengrad, you trace the same line that Süleyman's army followed in reverse, finishing at a bridge his own builders raised in 1529. Few day stages anywhere on the Sultans Trail compress so many layers of European and Ottoman heritage into a single afternoon of walking, and that cultural payoff is exactly what draws long-distance pilgrims to choose the Maritsa variant over the mountain main line.

Route Overview & Stages

The ST720 is a self-contained day stage, but most walkers tackle it as part of a sequence of Maritsa Valley legs. The table below breaks the immediate corridor into its working sections so you can plan water stops and timing.

Distances are approximate; the Sultans Trail Foundation publishes the definitive GPX tracks, and you should treat the figures above as planning estimates rather than surveyed measurements. The stage is comfortably walkable in five to seven hours at a steady pace, but the absence of a midway village means you carry everything you need from Lyubimets.

Highlights & Points of Interest

• Mustafa Pasha Bridge, Svilengrad — A 295-metre Ottoman stone bridge built in 1529 over the Maritsa River, with around 20 arches; it is the architectural centrepiece of Svilengrad and a fitting end point for a stage that shadows Süleyman's campaign.
• Lyubimets town centre — The starting hub, with cafés, a market and an Orthodox church; the last reliable place to load up on water, food and cash before the open valley.
• Maritsa River corridor — The broad Thracian river that the stage parallels; its banks are rich in herons, storks and migratory birds, especially in spring.
• Thracian vineyards — The valley around Lyubimets sits in a recognised Bulgarian wine region; rolling vine rows flank much of the route and several small cellars welcome visitors.
• Border tripoint country — Within a short drive lies the meeting point of Bulgaria, Greece and Turkey, a landscape layered with frontier history from Ottoman times to the Cold War.
• Svilengrad old quarter — Narrow lanes, a 20th-century synagogue and traditional Thracian houses cluster near the river crossing.
• Roadside Thracian tumuli — Low burial mounds dot the farmland between the two towns, silent reminders of the ancient Thracians who farmed this valley.
• Lyubimets monastery surrounds — Quiet wooded slopes north of town offer a contrasting shaded prelude to the exposed valley walking.

Best Time to Hike the ST720 Lyubimets-Svilengrad

Southeastern Bulgaria has a transitional Mediterranean-continental climate, and the Maritsa Valley is one of the hottest, driest corners of the country. That single fact shapes the whole calendar. Summer days from late June through August regularly exceed 35°C, and with almost no shade across the farmland sections the heat turns an easy 20 km into a genuine endurance test — this is a large part of why the stage carries an expert rating.

The single best month to walk the ST720 is May. As of 2026, spring brings daytime highs around 20–24°C, green vineyards, full rivers, and the peak of the bird migration along the Maritsa. April is a strong second choice, though earlier in the month rain can leave the field tracks muddy. At the other end of the year, late September and October are excellent too: the heat has broken, the grape harvest scents the air, and temperatures sit in a comfortable 18–25°C band. Winter walking is possible — the Sultans Trail is promoted as a year-round route outside the Bulgarian mountains — but short daylight, occasional frost and grey skies make the valley feel bleak between December and February.

Whatever month you choose, start early. Even in the shoulder seasons the back half of the day grows warm in the open valley, and reaching Svilengrad by mid-afternoon leaves a margin for navigation errors where the waymarking fades.

Practical Information

Accommodation

Both ends of the stage have beds, so you do not need to camp. In Lyubimets, small guesthouses and family-run hotels charge roughly €25–40 for a double room, often including breakfast. Svilengrad is the larger town and a regional crossing hub, with a wider choice of hotels and guesthouses in the €30–55 range; book ahead in summer, when border traffic and casino visitors fill rooms. Wild camping is legally grey in Bulgaria but generally tolerated if you are discreet, leave no trace and avoid private vineyards; a riverside pitch along the Maritsa is feasible for self-sufficient walkers carrying water. There are no staffed mountain huts on this lowland stage, so plan around the two towns rather than expecting refuges en route.

Getting There & Back

Both Lyubimets and Svilengrad sit on the main Sofia–Plovdiv–Istanbul rail line, which makes logistics straightforward. Direct trains run from Plovdiv (around 1.5–2 hours to Svilengrad) and from Sofia (roughly 4–5 hours). Svilengrad station is well placed for the end of the walk, and you can ride one stop back to Lyubimets to recover a car. The nearest major airport is Plovdiv, with Sofia Airport the larger international gateway about 240 km northwest; from Istanbul, Svilengrad is reachable by cross-border bus in around 4 hours. Bulgarian rail timetables and tickets are published by the national operator BDŽ (Bulgarian State Railways).

Permits & Fees

No permit or entry fee is required to walk the ST720 Lyubimets-Svilengrad — the route follows public roads, tracks and rights of way through farmland and riverside, none of it inside a protected national park requiring tickets. Because you are walking very close to the Turkish and Greek borders, carry your passport or EU ID card at all times; border police patrol the area and may ask for identification. The route and official GPX downloads are maintained by the Sultans Trail Foundation, the volunteer NGO that developed and signs the trail.

Gear & Packing List

The defining packing challenge here is water and sun, not altitude. Because there is no reliable resupply between Lyubimets and Svilengrad, carry at least 2.5–3 litres per person in warm weather, plus electrolyte tablets. A wide-brim hat, high-SPF sunscreen and lightweight long sleeves do more for comfort on this exposed stage than any technical mountain layer. Trail-running shoes or light hiking shoes suit the firm tracks and tarmac better than heavy boots.

For a single-day stage you want a small, well-ventilated pack. A vest-style pack such as the ADV Skin 12 or the slightly larger ADV Skin 20 carries water bottles up front where you can reach them, ideal for a hot, fast valley day. If you are walking several connected Sultans Trail stages and carrying camp gear, a roomier ultralight pack like the 2400 Windrider keeps weight down on long road miles. For choosing the right pack, our roundup of the best ultralight backpacks of 2026 compares the leading options. Because the exposed walking burns more energy than the modest elevation suggests, plan your snacks deliberately — our guide to how many calories you need hiking a full day helps you pack enough fuel without overloading.

Similar Trails You Might Like

If the cultural-corridor character of the Sultans Trail appeals, Bulgaria offers two outstanding long-distance options that pass through richer mountain terrain. The first is the Bulgarian section of the pan-European E4, which crosses the Rila and Pirin ranges with high passes and alpine lakes; the second is the E8 through Bulgaria, which the Sultans Trail itself partly follows on its way east. Both reward stronger navigation and fitness with far wilder scenery than the Maritsa Valley.

Frequently Asked Questions

When is the best time to hike the ST720 Lyubimets-Svilengrad?
May is the single best month, with daytime highs around 20–24°C, green vineyards and peak bird migration along the Maritsa River. April and the late September–October window are also very good. Avoid July and August, when valley temperatures regularly top 35°C and the long exposed sections with little shade make the stage genuinely dangerous in heat.

How difficult is the ST720 stage?
It is rated expert, but not because of climbing — the total gain is only around 250 m. The difficulty comes from roughly 20 km of exposed, shadeless walking, unreliable water between towns, fierce summer heat, and patchy waymarking across open farmland where a GPX track is essential. Fit hikers comfortable with self-navigation will find it manageable in cooler months.

How long does the walk take in a day?
The full ST720 covers about 20 km and most walkers complete it in five to seven hours at a steady pace, including breaks. There is no village midway, so it is designed as one continuous day stage from Lyubimets to Svilengrad. Starting early lets you finish by mid-afternoon and leaves a safety margin for any navigation errors.

Where can I stay along the route?
Both endpoints have accommodation. Lyubimets offers guesthouses and small hotels for roughly €25–40 a night, while Svilengrad, the larger town, has a wider choice in the €30–55 range. There are no mountain huts on this lowland stage. Discreet wild camping along the Maritsa is tolerated for self-sufficient walkers, but most people simply book a room at each end.

Do I need a permit to walk the ST720?
No permit or fee is required; the route uses public roads, tracks and riverside paths outside any ticketed national park. However, the stage runs very close to the Turkish and Greek borders, so always carry your passport or EU ID card. Border police patrol the area and may ask for identification, especially near the river and the frontier tripoint.
