ST702 Mladost3 - Red Cross

The ST702 Mladost3 – Red Cross is a short, easy point-to-point stage of the Sultans Trail in Bulgaria, running through the eastern districts of Sofia. With minimal elevation gain over largely flat urban and parkland terrain, it serves as a gentle connector on the 2,500 km cultural route from Vienna to Istanbul, ideal for a half-day walk close to the capital.

About the ST702 Mladost3 – Red Cross

The ST702 Mladost3 – Red Cross is one of the numbered stages of the Sultans Trail, a 2,500-kilometre (1,600-mile) long-distance hiking and cultural route that links Vienna with Istanbul. This particular section sits in Bulgaria, threading through the eastern side of Sofia between the Mladost 3 residential quarter and the area around the Red Cross (Червен кръст) junction. It is rated easy and is best understood not as a wilderness trek but as a waypoint stage that keeps the long Sultans Trail continuous as it crosses Bulgaria's capital.

The wider trail is named after Sultan Süleyman the Magnificent, whose 1529 military campaign toward Vienna the route loosely retraces. Süleyman left Istanbul on 10 May 1529 and reached Vienna 141 days later, on 23 September. The trail begins symbolically at St. Stephen's Cathedral in Vienna — whose great bell was forged from captured Ottoman cannons — and ends at the Süleymaniye Mosque in Istanbul, which holds the mausoleums of Suleiman and his wife Hürrem Sultan. Today the path has been deliberately recast as, in the words of its founders, "a path of peace and a meeting place for people of all faiths and cultures" rather than a monument to its military origins.

The trail was created by volunteers from the Netherlands-based NGO Sultans Trail Foundation, and it is part of the International Walking Network (IWN), one of the world's most significant hiking networks. It passes through nine countries: Austria, Slovakia, Hungary, Croatia, Serbia, Bulgaria, Greece (East Macedonia and Thrace) and Turkey. Across much of its length the route offers year-round walking with hotels and pensions, though the Bulgarian mountains further south present real seasonal challenges. You can read the project's own account of the full route on the official Sultans Trail website.

Because the ST702 stage runs through built-up Sofia, it is fully walkable year-round and requires no technical skill. Walkers use it to move between the city's southeastern neighbourhoods and to connect with the longer mountain stages that lead south toward the Greek border. The OpenStreetMap description sums it up plainly: a "stage in the Sultans Trail, a historic and cultural long-distance hiking route from Vienna to Istanbul." The trail also gained wider recognition when the BBC featured it in the 2020 series Pilgrimage: The Road to Istanbul.

Route Overview & Stages

The ST702 Mladost3 – Red Cross is a single connector stage. The table below places it in the context of the Sultans Trail's wider Bulgarian section so you can see how it fits the route as a whole. Exact stage distances on the Bulgarian segment vary by waypoint; figures here describe the character of each leg rather than surveyed kilometre marks.

The whole Bulgarian section overlaps in places with the E8 European long-distance path, which is worth knowing if you plan to extend your walk into a longer itinerary. The ST702 stage itself is waymarked as part of the Sultans Trail's numbered Bulgarian sequence, and because it sits entirely within Sofia, route-finding is straightforward: follow the city's eastern boulevards and park connectors between the two named endpoints, using the metro line as a constant orientation aid.

Highlights & Points of Interest

• Mladost 3 quarter — a large planned residential district in southeastern Sofia, the western anchor of the stage, with metro access and easy resupply at supermarkets and cafés.
• Red Cross junction (Червен кръст) — the eastern endpoint, a recognised Sofia landmark and transport node that links onward bus and tram routes.
• South Park (Yuzhen Park) — within easy reach of the route, Sofia's most popular green space, with shaded paths, ponds and open lawns for a rest stop.
• Vitosha Mountain backdrop — the 2,290 m Cherni Vrah summit of Vitosha Nature Park dominates the southern skyline throughout the stage.
• Sofia metro line — the city's clean, frequent metro shadows much of the eastern districts, making bail-out or shortcut points unusually convenient for a long-distance trail.
• Boulevard tree avenues — Sofia's wide, linden-lined boulevards give the urban walking a surprisingly green, walkable character in spring and early summer.
• Local sweet shops and bakeries — the Mladost and Lozenets neighbourhoods are dotted with bakeries selling banitsa and fresh bread, perfect trail fuel.
• Onward link to the wider Sultans Trail — this stage connects to the longer cultural route that ultimately ends at the Süleymaniye Mosque in Istanbul.

Best Time to Hike the ST702 Mladost3 – Red Cross

Because this is an urban stage, it can be walked in any month of the year. That said, the experience differs sharply by season, and as of 2026 the most comfortable window for walking through Sofia is clearly the shoulder seasons.

May is the single best month. In May 2026 expect daytime highs around 20–23 °C, long daylight, the city's parks in full bloom, and dry, dust-free pavements. April and early June are close runners-up, with April occasionally bringing rain showers and June starting to warm. September and early October offer a second excellent window, with stable, mild weather around 18–24 °C and fewer crowds.

Summer (July–August) is walkable but hot: Sofia regularly sees 30–34 °C, and the open boulevards offer little shade at midday, so start early and carry plenty of water. Winter (December–February) brings cold (often below 0 °C), occasional snow and icy pavements; the walking itself stays easy but is less pleasant, and short daylight hours limit how much you can combine with neighbouring stages. If you intend to continue onto the mountain stages south of Sofia, note that those higher sections of the Bulgarian Sultans Trail present real seasonal challenges and are best left to late spring through early autumn, when snow has cleared from the Vitosha and Rila approaches.

Practical Information

Accommodation

As an in-city stage, the ST702 Mladost3 – Red Cross has the easiest accommodation of any part of the Sultans Trail. Sofia offers everything from hostels to four-star hotels. Expect hostel dorm beds from about €12–18 per night, private guesthouse rooms from around €30–45, and mid-range hotels from roughly €50–80. The Mladost and Lozenets districts near the route have numerous apartment rentals from about €40 per night. Unlike the remote mountain sections of the trail — where tent camping is sometimes recommended in both Hungary and Bulgaria — you will not need to camp here; booking ahead is only really necessary during major events or peak summer.

Getting There & Back

Sofia Airport (SOF) is the nearest international gateway, just 6–8 km from the eastern end of the stage and connected to the city by Metro Line 1 in about 20 minutes. Sofia Central Railway Station links the city to the rest of Bulgaria and to international services toward Serbia and Greece. Within the city, the Sofia Metro, trams and buses reach both Mladost 3 and the Red Cross junction directly; a single public-transport ticket costs roughly €0.80–1.00, and tickets and live timetables are published by the city's transport operator at the Sofia Urban Mobility Centre. From the airport you can be at the trailhead within 20–30 minutes, making this one of the most accessible trail stages in the country.

Permits & Fees

No permits are required to walk the ST702 Mladost3 – Red Cross or any part of the Sultans Trail in Bulgaria. The trail is free to use, runs on public streets, paths and parkland, and has no entry fee. If you extend south into Vitosha Nature Park, access there is also free, though some facilities and the chairlift charge separately. For the full multi-country route, carry a valid passport, as several stage transitions involve international border crossings between Bulgaria, Serbia, Greece and Turkey.

Gear & Packing List

For a short, easy urban stage you need very little: comfortable trail shoes, a light daypack, water, snacks and a phone with offline maps. If, however, you are using this stage as the start of a longer Sultans Trail itinerary across Bulgaria, your kit list grows considerably and a well-fitted pack becomes the foundation of everything else.

For a fast, light day on the ST702, a running-style vest such as the ADV Skin 12 carries water and a layer with no fuss. For multi-day continuation onto the mountain stages, a larger ultralight pack like the 2400 Windrider or the roomier 3400 Windrider handles camping gear comfortably. If you want guidance on choosing one, our roundup of the best ultralight backpacks of 2026 tests and ranks seven leading models. Because longer days burn far more energy than a casual city walk, it is worth reading how many calories you need hiking a full day before you plan your food and resupply.

May is the single best month, with comfortable highs of 20–23 °C, dry pavements and parks in full bloom. April, early June, September and early October are also excellent. As an urban stage it can be walked year-round, but summer can reach 30–34 °C and winter brings cold and occasional icy pavements, making the shoulder seasons most pleasant.

How difficult is this stage?
It is rated easy. The ST702 Mladost3 – Red Cross runs across flat urban Sofia with minimal elevation gain — under about 50 metres — on streets, paths and parkland. No technical skill, scrambling or navigation experience is needed. It suits walkers of all fitness levels, families and anyone wanting a gentle introduction to the wider Sultans Trail before tackling its harder mountain sections further south.

How far is it and how long does it take?
The stage is a short urban connector of roughly 4–6 kilometres, walkable in one to two hours at an easy pace including rest stops. As part of the 2,500 km Sultans Trail, it is designed as a single short leg rather than a full hiking day, so most walkers combine it with adjoining Sofia stages or use it to reach onward transport.

Where can I stay along the route?
Because the stage runs through central-eastern Sofia, accommodation is plentiful. Hostel dorm beds start around €12–18 per night, guesthouse rooms from €30–45, and mid-range hotels from €50–80. Apartment rentals in the Mladost and Lozenets districts begin near €40. Camping is unnecessary here, unlike the remote mountain stages of the trail where tents are sometimes recommended.

Do I need a permit or pay any fees?
No. The ST702 Mladost3 – Red Cross requires no permit and has no entry fee. It follows public streets, paths and parkland that are free to use. If you continue onto the broader multi-country Sultans Trail, carry a valid passport for international border crossings, and budget separately for any optional facilities such as the Vitosha chairlift south of the city.
