ST706 Ihtiman - Momin Prohod

The ST706 Ihtiman – Momin Prohod is an easy point-to-point stage of the long-distance Sultans Trail in western Bulgaria, gaining roughly 150 m of elevation across gentle valley terrain over a single day. Rated easy, it links the market town of Ihtiman with the spa village of Momin Prohod, following a historic Vienna-to-Istanbul corridor through the foothills of the Sredna Gora.

About the ST706 Ihtiman - Momin Prohod

The ST706 Ihtiman – Momin Prohod is a designated stage on the Sultans Trail, a 2,500-kilometre cultural walking route that runs from St. Stephen's Cathedral in Vienna to the Süleymaniye Mosque in Istanbul. The full trail crosses nine countries — Austria, Slovakia, Hungary, Croatia, Serbia, Bulgaria, Greece and Turkey — and is catalogued in OpenStreetMap as part of the International Walking Network (IWN), one of the world's most significant hiking frameworks. This particular section sits in the Bulgarian heartland of the route, in Sofia Province, where the trail threads between Sofia and the Maritsa valley.

The route is named after Sultan Süleyman the Magnificent, whose 1529 military campaign toward Vienna the path traces in reverse. Süleyman departed Istanbul on 10 May 1529 and reached the walls of Vienna 141 days later, on 23 September 1529. Today the Sultans Trail Foundation, a Netherlands-based NGO, manages and promotes the corridor not as a martial monument but as "a path of peace and a meeting place for people of all faiths and cultures." Walking the ST706 places you on a thin slice of that 500-year-old story.

Ihtiman, the western endpoint, is a town of roughly 12,000 people sitting at about 630 m above sea level in a basin ringed by the Sredna Gora hills to the north and the Ihtiman Sredna Gora to the south. Momin Prohod, the eastern endpoint, is a small spa settlement attached to the town of Kostenets, long known for its warm mineral springs. The walk between them is short, low and forgiving — an ideal introduction to the Bulgarian portion of the trail for hikers who are not ready for the bigger Rila and Rhodope mountain stages further south.

Because the Sultans Trail follows old roads, field tracks and quiet asphalt through this section rather than alpine paths, the ST706 is best understood as a cultural and connective stage. It bridges two waypoints rather than chasing summits, and it rewards walkers who enjoy reading the landscape — Ottoman-era road alignments, Orthodox village churches, and the broad agricultural plains that fed armies and merchants for centuries.

Route Overview & Stages

The ST706 is itself one stage of the larger Bulgarian section, which the Sultans Trail Foundation divides into walking days between Sofia and the Greek border. The table below places the Ihtiman – Momin Prohod leg in context with its immediate neighbours. Distances are approximate, as the OSM relation does not publish an exact figure for every sub-stage.

For the ST706 itself, plan on roughly four to five hours of walking at an unhurried pace. The terrain is overwhelmingly flat to rolling, with the only sustained climb being the gentle rise out of the Ihtiman basin before the descent toward the Momin Prohod springs. Anyone comfortable with a long walk in the countryside can complete it in a single morning. Waymarking on the Bulgarian Sultans Trail uses the route's distinctive crescent-and-star logo on posts, trees and walls, supplemented by the GPS tracks the foundation publishes for each leg; on the ST706 the markings are reinforced where the trail crosses roads and farm tracks, but a downloaded track on your phone remains the most dependable navigation aid given that some rural signage has faded.

Highlights & Points of Interest

• Ihtiman town centre — A traditional Bulgarian market town at 630 m, with an Orthodox church, a small history museum and cafés clustered around the central square; a natural staging point for the walk.
• Momin Prohod mineral springs — The spa village's hot springs emerge at around 60–65 °C and have drawn visitors since the early 20th century; the balneological centre is the trail's eastern reward.
• Ihtiman Sredna Gora foothills — Low forested ridges that frame the valley, offering shaded field tracks and open views across the agricultural basin.
• Vakarel corridor — The historic route alignment west of Ihtiman that the Sultans Trail follows, tracing the old Sofia–Plovdiv road used by Ottoman caravans and armies.
• Kostenets vicinity — Just beyond Momin Prohod, the larger Kostenets municipality holds a well-known waterfall and the gateway to the Rila foreland.
• Sredna Gora viewpoints — Gentle rises along the route give panoramas toward the distant Rila massif to the south, the trail's next great chapter.
• Village churches and fountains — Small Orthodox chapels and the traditional stone cheshma (public fountains) punctuate the walk and offer welcome shade and water.
• Roadside Ottoman heritage — Faded bridges and road markers recall the 16th-century military and trade route that gives the Sultans Trail its name.

Best Time to Hike the ST706 Ihtiman - Momin Prohod

Because the ST706 stays low — between roughly 600 and 700 m — it has one of the longest hiking windows of any Sultans Trail section in Bulgaria. The corridor is walkable for most of the year, but conditions vary sharply by season.

Spring (April–June) is the standout window. By late April the basin greens up, wildflowers fill the field margins, and daytime temperatures sit comfortably between 15 and 22 °C. The single best month is May: rivers run full, the forested foothills are at their freshest, and the heat of the plain has not yet arrived. As of 2026, late-spring weather in Sofia Province has trended warm and settled, making May the most reliable choice for dry tracks and clear views toward Rila.

Summer (July–August) brings high heat to the valley floor, where afternoon temperatures regularly exceed 30 °C and shade is limited on the open farmland sections. Early starts are essential, and the warm mineral springs of Momin Prohod feel less inviting in the heat. Autumn (September–October) is the second-best window, with stable weather, cooler air and golden foliage across the Sredna Gora. Winter (November–March) is feasible on the low ground but can bring mud, fog and occasional snow; the trail is rarely impassable but loses much of its appeal. One practical advantage of the low elevation is that the ST706 can serve as a shoulder-season warm-up while the higher Rila and Pirin stages of the Sultans Trail are still snowbound, letting you build fitness in March or April before committing to the mountains in June.

Practical Information

Accommodation

Both endpoints offer beds, which makes the ST706 easy to slot into a multi-day itinerary. In Ihtiman, small guesthouses and family hotels charge roughly €25–45 per night for a double room, often including breakfast. Momin Prohod and neighbouring Kostenets cater to spa visitors, so expect a wider range: simple rooms from around €30, and balneological hotels with mineral baths from €50–80 per night. Camping is tolerated in rural Bulgaria with landowner permission, and the Sultans Trail Foundation advises that tenting may be necessary in parts of Bulgaria where formal lodging is sparse — though on this stage it is rarely needed given the two well-served towns.

Getting There & Back

Ihtiman sits directly on the Sofia–Plovdiv railway line. Frequent trains from Sofia Central Station reach Ihtiman in about 50–70 minutes, and the station is a short walk from the town centre. From Momin Prohod, return trains run from the nearby Kostenets station back to Sofia in around 75–90 minutes, or onward toward Plovdiv. The nearest major airport is Sofia Airport (SOF), roughly 60 km west of Ihtiman and connected to the rail network via Sofia's metro and central station. Buses along the Trakia motorway corridor also serve both towns. Schedules for Bulgarian State Railways can be checked through the national operator BDŽ.

Permits & Fees

No permit is required to walk the ST706. The Sultans Trail is a free, open cultural route on public roads and tracks, and there are no entry fees for this stage. There are no national-park gates on this low section, though hikers continuing south toward Rila should note that the Rila Monastery and Rila National Park have their own visitor rules. Route details, GPX downloads and the latest waymarking notes are published by the Sultans Trail Foundation.

Gear & Packing List

The ST706 is a low, short, easy day, so heavy mountaineering kit is overkill — but Bulgarian valley weather can swing from warm sun to sudden showers, so pack for variability. A lightweight 30–40 litre daypack is ample for this stage. The Abisko Hike 35 is a comfortable choice for a single-day walk with room for layers, lunch and water. If you are linking the ST706 into a longer multi-day push toward Rila, a larger ultralight pack such as the 2400 Windrider or the roomier 3400 Windrider carries several days of food and a tent without weighing you down.

Essentials for this stage: a sun hat and sunscreen for the exposed farmland, a packable rain shell, sturdy trail shoes (boots are unnecessary on this terrain), at least 1.5 litres of water, and a small first-aid kit. Trekking poles are optional given the gentle profile. For ideas on dialling in a lighter base weight before a longer Sultans Trail traverse, see our roundup of the best ultralight backpacks of 2026.
