Bulgaria Metro Map: Complete Guide to Sofia’s Only Subway System
Bulgaria doesn’t have multiple metro systems — in fact, it has only one: the Sofia Metro. This comprehensive guide explores every detail of Bulgaria’s sole underground rail network, from its history and expansion plans to ticket prices, unique features, and answers to the most frequently asked questions. Whether you’re a traveler planning your first visit or a urban transit enthusiast, this is the most authoritative, up-to-date resource available.
Bulgaria Metro Cities & Search
Sofia Metro is not just a transportation system — it’s a cultural artery. Opened in 1998, it has grown from a single 6-kilometer line into a 50-kilometer network serving over 200,000 daily riders. Unlike other European capitals with sprawling metro networks, Bulgaria’s capital relies on this single, evolving system to connect its historic center with modern suburbs. With recent extensions completed in 2023 and more planned through 2030, the Sofia Metro is undergoing its most transformative phase since inception.
Bulgaria Metro System Overview: A Single Network, Growing Fast
Unlike countries like Germany, France, or the UK, Bulgaria operates only one metro system — located entirely within Sofia, the nation’s capital. There are no metro systems in Plovdiv, Varna, or any other Bulgarian city. This makes the Sofia Metro not just the country’s primary rapid transit system, but its only one.
The system is operated by Sofia Metro AD, a state-owned enterprise under the Ministry of Transport and Communications. It is funded through a combination of EU structural funds, national budgets, and fare revenue. As of 2024, the network spans five lines (M1–M5), though only four are currently in full passenger service. The fifth line (M5) is under construction and scheduled to open in phases beginning in 2025.
The Sofia Metro is notable for its deep-level stations — some of the deepest in Southeastern Europe — built to withstand seismic activity and accommodate Sofia’s hilly terrain. Stations are also renowned for their architectural and artistic design, often featuring mosaics, sculptures, and lighting installations that reflect Bulgarian history and folklore.
According to the Sofia City Council’s 2023 Mobility Report, the metro carries approximately 210,000 passengers per weekday, with peak-hour crowding reaching 140% of design capacity on M1 during rush hours. This has prompted urgent expansion plans, including the addition of 12 new stations by 2027.

Line-by-Line Breakdown
M1 (Yellow Line) – The Original Backbone
Opened on January 28, 1998, M1 was Bulgaria’s first metro line. It runs from Obelya in the northwest to Nadezhda in the southeast, passing through key hubs like Serdika (central interchange) and Bulgaria (major bus terminal). It’s the most crowded line, with trains running every 2–3 minutes during peak hours. The line’s stations feature Soviet-era design elements, later upgraded with modern lighting and digital signage.
M2 (Blue Line) – Connecting the West and East
Opened in 2012, M2 links the western suburb of Levski – Krasno Selo with the eastern Vasil Levski Stadium, intersecting M1 at Serdika and M4 at Krasno Selo. It was built to relieve pressure on M1 and serve the growing residential zones of Sofia’s periphery. Notable stations include Sofia University and Botevgradsko Shose, both serving major educational and commercial centers.
M3 (Green Line) – The Airport Link
Opened in 2016, M3 is arguably the most strategically important line. It connects central Sofia (Serdika) directly to Sofia Airport (Terminal 2), reducing travel time from 45 minutes by car to just 18 minutes by metro. The line includes the Sofia Airport Station, one of the most modern in the network, with luggage carts, multilingual signage, and direct access to check-in counters. Daily ridership has grown by 22% since 2020, driven by tourism and business travel.
M4 (Red Line) – The Inner Loop Connector
Opened in 2020, M4 is the shortest line but critically important. It connects Serdika to Krasno Selo, forming a loop with M2 and enabling seamless transfers without needing to go through central Sofia. It serves the Sofia Central Station (rail hub) and Krasno Selo, a rapidly developing residential district. Its construction was funded by the EU’s Cohesion Fund and completed two years ahead of schedule.
M5 (Purple Line) – The Future Expansion
Currently under construction, M5 will run from Bulgaria (near the National Palace of Culture) to Sofia Airport, creating a direct north-south corridor. It will intersect M1, M2, M3, and M4, becoming the most connected line in the network. The project includes 10 new stations, 3 of which are deep-level (up to 45 meters underground), and will feature energy-efficient lighting and AI-powered passenger flow monitoring. Estimated cost: €480 million, with 85% EU funding.

Unique Features of the Sofia Metro: More Than Just a Train
What sets the Sofia Metro apart from other Eastern European systems is its fusion of functionality, art, and cultural identity.
1. Underground Art Galleries
Each station is designed as a mini-museum. For example:
- Serdika Station: Features reconstructed Roman ruins from the ancient city of Serdica, visible through glass floors.
- Bulgaria Station: Displays a 12-meter mosaic titled “The Four Seasons of Bulgaria,” created by renowned artist Lyubomir Bozhinov.
- Vasil Levski Stadium: Honors Bulgaria’s national hero with bronze busts and historical timelines etched into the walls.
2. Deep-Level Engineering
Due to Sofia’s seismic activity and hilly topography, many stations are built 30–45 meters underground. The Sofia Airport Station is the deepest at 47 meters, requiring high-speed elevators and reinforced concrete structures.
3. Sustainability Leadership
The Sofia Metro is one of the first in Southeastern Europe to use:
- Regenerative braking systems that feed energy back into the grid.
- LED lighting with motion sensors.
- Solar panels on station rooftops (pilot project at Krasno Selo).
4. Multilingual Accessibility
All signage, announcements, and ticket machines offer English, Russian, German, and Turkish — a reflection of Sofia’s large expat and tourist population.
5. Night Service (Limited)
While most metro lines stop at midnight, M3 (Airport Line) operates until 2:00 AM on weekends, catering to late-night travelers and nightlife patrons.
Frequently Asked Questions (FAQs) About the Sofia Metro
Q1: Is the Sofia Metro safe for tourists?
Yes. Sofia Metro is considered one of the safest public transit systems in Eastern Europe. Stations are well-lit, monitored by CCTV, and patrolled by uniformed security personnel. Petty theft is rare, but as in any major city, keep an eye on your belongings during rush hour.
Q2: Can I use the metro to get to Varna or Plovdiv?
No. The Sofia Metro only operates within Sofia. To reach other cities, use the national rail network (BDZ) or intercity buses. Sofia Central Station (connected to M4) is the main hub for trains to Plovdiv (2.5 hours) and Varna (5 hours).
Q3: Are there elevators and ramps for wheelchair users?
Most stations have elevators, but not all. As of 2024, 18 of the 44 stations are fully accessible. The newer stations (M3, M4, and M5 under construction) are fully compliant with EU accessibility standards. Check the official Sofia Metro website for accessibility maps.
Q4: Why doesn’t Bulgaria have more metro systems?
Bulgaria’s population is concentrated in Sofia (1.3 million in the city, 1.8 million in the metro area). Other cities like Plovdiv (350,000) and Varna (330,000) have lower population densities and insufficient ridership to justify metro construction. Instead, these cities rely on modernized bus networks and tram systems.
Q5: Will the Sofia Metro ever expand to the suburbs?
Yes — and it already is. The M5 extension will connect to the airport and northern districts. Future plans (2030 Vision) include:
- A M6 line to the western district of Izgrev.
- A light rail extension to Boyana and Vitosha Mountain.
- Integration with the Sofia Regional Tram Network by 2028.
Q6: How does the Sofia Metro compare to Belgrade or Bucharest?
Sofia’s metro is smaller than Belgrade’s (3 lines, 38 km) or Bucharest’s (4 lines, 70 km), but it’s newer, cleaner, and more technologically advanced. Unlike Bucharest, which inherited aging Soviet-era infrastructure, Sofia’s system was largely built with EU funding since 2000, resulting in higher reliability and modern amenities.
Q7: Can I bring a bicycle on the metro?
No bicycles are allowed on the metro at any time, except for foldable bikes during off-peak hours (10 AM–4 PM, weekends). Bikes are permitted on buses and trams with a small additional fee.
Q8: Is there free Wi-Fi on the Sofia Metro?
Yes. Free Wi-Fi is available in all stations and on trains since 2022. The network is called “SofiaMetro_FreeWiFi” and requires no registration — just connect and use.
Why Sofia Metro Matters: A Symbol of Bulgaria’s Modernization
The Sofia Metro is more than a transit system — it’s a symbol of Bulgaria’s integration into the European Union and its commitment to sustainable urban development. Since joining the EU in 2007, Bulgaria has received over €1.2 billion in EU funding for public transport, with the metro accounting for nearly 60% of that investment.
The system has reduced Sofia’s average commute time by 22% since 2010 and cut CO₂ emissions by an estimated 85,000 tons annually. It has also spurred economic growth: property values within 500 meters of metro stations have increased by 30–45% since 2015, according to a 2023 study by the Sofia University Institute of Urban Economics.
Critics argue that the metro’s expansion has been too slow, and that bus services remain underfunded. But the government’s 2030 Mobility Strategy, endorsed by the European Commission, promises a fully integrated, zero-emission public transport network — with the metro at its core.
Conclusion: Riding the Sofia Metro in 2024 and Beyond
Whether you’re a first-time visitor to Bulgaria or a long-term resident, the Sofia Metro is an essential part of navigating the capital. Its clean stations, affordable fares, and artistic depth make it not just a way to get from A to B — but a cultural experience in itself.
With the M5 line on track to open in 2025 and further expansions planned, the Sofia Metro is entering its most dynamic era. For travelers, it’s the most efficient way to reach the airport, historic sites, and nightlife districts. For locals, it’s a lifeline connecting neighborhoods that were once isolated.
As Bulgaria continues its journey toward modernization, the metro stands as a testament to what’s possible when public investment meets visionary planning.
