ST705 Paunovo - Ihtiman

The ST705 Paunovo – Ihtiman is an easy ~15 km point-to-point stage on the Sultans Trail in western Bulgaria, gaining roughly 250 m of elevation across a single half-day of walking. Following gentle valley tracks and rural lanes through the Ihtiman basin, it is one of the most relaxed links on the historic 2,500 km cultural route from Vienna to Istanbul.

About the ST705 Paunovo – Ihtiman

The ST705 Paunovo – Ihtiman is a single waymarked stage on the Sultans Trail, a 2,500 km (1,600 mile) long-distance cultural route that runs from St. Stephen’s Cathedral in Vienna, Austria, to the Süleymaniye Mosque in Istanbul, Turkey. The trail is part of the International Walking Network (IWN) and is managed by the Sultans Trail Foundation, a Netherlands-based NGO that develops the path as “a path of peace and a meeting place for people of all faiths and cultures.”

This particular stage sits in Sofia Province, in the Ihtiman basin southeast of the Bulgarian capital. It connects the small village of Paunovo with the market town of Ihtiman, a settlement of roughly 11,000 people that has sat on the historic Vienna–Istanbul corridor for centuries. The route follows the line of the old imperial road — the same diagonal that Ottoman armies, traders and pilgrims have used for more than 500 years.

The Sultans Trail is named after Sultan Süleyman Kanuni (Suleiman the Magnificent), who marched Ottoman forces westward in 1529. He departed Istanbul on 10 May and reached Vienna on 23 September — a journey of 141 days. Modern walkers retrace that line in reverse, and stages such as ST705 break the Bulgarian section into manageable, low-difficulty days. Rated easy, the Paunovo – Ihtiman leg involves no technical terrain, no exposure and only modest climbing, making it suitable for hikers of almost any fitness level.

For context, the Bulgarian portion of the Sultans Trail threads through Sofia, Samokov, the Rila Monastery, Velingrad, Smolyan and Kardzhali, with an alternative branch running through the Maritsa Valley via Plovdiv and Svilengrad. ST705 belongs to the lower-lying basin section between Sofia and the Sredna Gora hills, away from the higher Rila routes that demand more planning.

What makes this stage worth walking is not dramatic scenery but a sense of continuity with a 500-year-old corridor of movement. The same broad valley that carried 16th-century Ottoman columns, Byzantine couriers and Roman legionaries before them is still farmed today, and the Sultans Trail deliberately follows that historic line rather than chasing summits. The Sultans Trail was also featured in the BBC’s 2020 television series Pilgrimage: The Road to Istanbul, which raised the profile of the wider route and brought a steady trickle of international walkers to towns like Ihtiman. For anyone section-hiking the Bulgarian leg, ST705 is a natural rest-day-style stage: short, navigable, and ending in a town with a railway station, shops and a hot meal.

Route Overview & Stages

ST705 is one stage within the wider Bulgarian sequence. The table below places it in context with the surrounding legs so you can see how it fits into a multi-day itinerary. Distances are approximate and based on the published Sultans Trail staging.

The Paunovo – Ihtiman day itself follows a mix of gravel farm tracks, quiet asphalt lanes and short field paths. There is no scrambling and no significant exposure; the only real route-finding is at field junctions where the Sultans Trail’s waymarking can be sparse, so a downloaded GPX track is strongly recommended. Total ascent is modest at roughly 250 m, spread gently over the 15 km, and the descent into Ihtiman is similarly gradual. Most reasonably fit walkers complete the stage in 4–5 hours including breaks, and the terrain stays firm and dry through the late-summer and early-autumn months when basin tracks are at their best.

Highlights & Points of Interest

• Paunovo village — A tiny rural settlement at the start of the stage, with a small village church and a working agricultural landscape that has changed little in decades.
• The old imperial road — Sections of ST705 trace the historic diagonal route (the Via Militaris / Diagonal Road) that linked Belgrade to Constantinople and carried Suleiman’s armies in 1529.
• Ihtiman basin farmland — A broad, gently sloping plain ringed by the Sredna Gora and Ihtimanska Sredna Gora hills, offering long open views and easy walking.
• Ihtiman town centre — The market town that gives the stage its name, with cafes, shops, a railway station and Ottoman-era heritage along the old trade route.
• Ihtiman clock tower and old quarter — Modest but atmospheric reminders of the town’s role as a waystation on the Vienna–Istanbul corridor.
• Trayanovi Vrata (Trajan’s Gate) approach — Just beyond Ihtiman lies the historic mountain pass where a famous 986 battle was fought; a worthwhile detour for history-minded walkers.
• Local Orthodox chapels — Several small roadside chapels punctuate the route, reflecting the trail’s theme as a meeting place for people of all faiths.
• Sredna Gora foothill panoramas — On clear days the southern horizon opens toward the higher Rila massif, a reminder of the bigger mountains the Sultans Trail also crosses.

Best Time to Hike the ST705 Paunovo – Ihtiman

The Sultans Trail Foundation notes that the route is walkable year-round except in the Bulgarian mountains — and because ST705 stays in the low Ihtiman basin (around 630–700 m), it has one of the longest viable seasons of any Bulgarian stage. That said, the experience varies sharply by month.

Spring (April–May) brings green farmland, wildflowers and mild daytime temperatures of 12–20 °C, though field tracks can be muddy after rain. Summer (June–August) is hot and exposed, with basin temperatures regularly hitting 30–35 °C and little shade across the open farmland; carry extra water and start early. Autumn (September–October) offers stable, dry, comfortable weather, firm tracks and golden light over the harvested fields.

The single best month to walk ST705 is September. As of 2026, late summer into early autumn delivers the most reliable combination of dry trails, warm-but-not-scorching daytime temperatures around 22–26 °C, and long usable daylight before the November rains arrive. Winter (December–February) is technically passable but cold, often frosty, and far less pleasant on the exposed basin sections. If you are linking ST705 with the higher Rila stages further south, note that those mountain sections close earlier and reopen later than this lowland leg, so plan your wider itinerary around the alpine portions rather than around the basin. For a single-stage outing focused only on Paunovo to Ihtiman, the window from mid-April through late October is comfortable, with September the clear standout for settled weather.

Practical Information

Accommodation

Ihtiman is the obvious overnight base at the end of the stage. The town has a handful of small guesthouses and family-run hotels, typically priced at €25–€45 per night for a double room, often including breakfast. Budget rooms and private rentals can be found from around €18–€30. Paunovo itself has essentially no formal accommodation, so most walkers arrive from a previous stage or are dropped off.

Wild and informal camping is widely practised along rural Bulgarian routes; there are no formal campsites on this specific stage, but discreet camping in the basin’s field margins is generally tolerated. For a proper base with more choice, Sofia (about 50 km northwest) offers hostels from €12–€20 per dorm bed and is an easy train ride away.

Getting There & Back

Ihtiman sits directly on the Sofia–Plovdiv railway line, which makes this stage unusually easy to reach by public transport. Ihtiman railway station has regular daily trains to and from Sofia (journey time roughly 50–70 minutes) operated by Bulgarian State Railways. Check current timetables with the national operator BDZ (Bulgarian State Railways) before travelling.

Paunovo, the start point, is a small village reached by local road; the simplest approach is to take a regional bus or taxi from Ihtiman or Sofia, or to walk in on the preceding Sultans Trail stage. The nearest major airport is Sofia Airport (SOF), around 60 km away, with a city-centre transfer of roughly 30–40 minutes by metro and then onward train to Ihtiman. Plan logistics around the official staging published by the Sultans Trail Foundation.

Permits & Fees

No permits or entry fees are required to walk ST705 Paunovo – Ihtiman. The Sultans Trail crosses public roads, farm tracks and open countryside that are freely accessible. There are no national-park gates or paid checkpoints on this stage. The only costs you should budget for are accommodation, food, local transport and any optional GPX or guidebook materials from the trail foundation.

Gear & Packing List

This is an easy, low-altitude day, so heavy mountaineering kit is unnecessary — the priority is sun protection, water and comfortable footwear for mixed gravel and asphalt. A lightweight 35–55 litre pack is plenty for a single stage or a short multi-day section. For ultralight section-hikers, the 2400 Windrider handles a minimalist load comfortably, while those carrying camping gear or food for several Bulgarian stages may prefer the larger 3400 Windrider. If you want a more structured pack with a supportive hipbelt for warm-weather basin walking, the Abisko Hike 35 is a solid mid-size option. If you are still deciding, our roundup of the best ultralight backpacks of 2026 compares seven packs tested and ranked.

Beyond the pack, bring at least 2–3 litres of water capacity (resupply points between Paunovo and Ihtiman are limited), a sun hat and high-SPF sunscreen for the exposed farmland, sturdy trail shoes rather than heavy boots, and a phone or GPS with a downloaded track. Because the open basin offers little shade, snacks and electrolytes matter more than usual — see our guide on how many calories you need hiking a full day to plan your food.
