Getting Around Sofia: A Complete Public Transport Guide

Sofia‘s public transport has a reputation among visitors for being confusing, cash-dependent, and occasionally unreliable. Some of that reputation was earned — but 2026 is a different story. The metro has expanded, contactless bank card payment now works across most of the network, and Schengen membership has simplified arrivals for EU travellers connecting through the airport. If you arrive expecting chaos, you’ll likely be pleasantly surprised. This guide cuts through the noise and tells you exactly how to get around Sofia without a car.

The Sofia Metro — Lines, Coverage, and What’s New in 2026

The Sofia Metro is the fastest and most straightforward way to move across the city. It runs on three lines, all operated by Metropolitan EAD, and covers the key zones most visitors care about — the airport, the city centre, key residential districts, and the Business Park in the south.

Line 1 (M1) runs east–west, connecting Tsarigradsko Shose in the east through the centre (including Serdika and Sofia University stations) and out toward Lyulin in the west. This is the line most travellers use daily for central Sofia movement.

Line 2 (M2) runs north–south and is the one connecting Sofia Airport (Terminal 2) directly to the city centre. The journey from the airport to Serdika — the main interchange hub in central Sofia — takes roughly 20 minutes. If you land in Sofia and want to reach your accommodation quickly, this is your first move.

Line 3 (M3), which opened progressively in phases, extended significantly in late 2025. By early 2026, it connects the Ovcha Kupel district in the southwest through the centre and out to the Student City area in the east. This line relieved enormous pressure on the bus network in neighbourhoods that had poor metro access for decades.

The metro runs from approximately 05:30 to 00:00 daily. Trains run every 3–5 minutes during peak hours and every 7–10 minutes late at night. Stations are clean, reasonably well-signposted in both Bulgarian and English, and platform screen doors have been installed on all M3 stations.

Trams, Trolleybuses, and City Buses — The Surface Network Explained

The metro doesn’t go everywhere, and that’s where Sofia’s dense surface network fills the gaps. The city operates a mix of trams, electric trolleybuses, and diesel buses across several hundred routes — all managed by Gradski Transport EAD.

Trams are the most useful for visitors after the metro. The tram network covers central and inner-city streets where the metro has no presence. Tram 1 and Tram 7 are workhorses for getting around the Oborishte and Lozenets neighbourhoods. Tram 10 connects the NDK (National Palace of Culture) area with Orlov Most and beyond. Trams run on fixed tracks, so they can slow down in traffic, but they’re reliable and you always know the route.

Trolleybuses run on overhead electric wires and cover many of the city’s main boulevards. They’re quiet, non-polluting, and generally on time. Trolleybus 2 is particularly useful for moving along Dondukov Boulevard between the centre and the Nadezhda district.

City buses cover the outer neighbourhoods, suburban zones, and areas between metro stations. They can be crowded and slower than other options, but they’re often the only direct connection to places like Boyana (useful if you’re visiting the Boyana Church or the National History Museum) or Dragalevtsi.

All surface vehicles display their route number and key stops on the front. At busier stops, digital display boards now show real-time arrival information in Bulgarian and English — this was rolled out across the main corridors in 2025. For routes outside the centre, the Moovit app and Google Maps both have solid real-time data for Sofia in 2026 and are genuinely reliable tools.

One sensory reality worth knowing: trams in Sofia make a distinctive metallic screech as they round tight corners — perfectly audible from a side street two blocks away. Use that sound as a homing signal when you’re trying to locate a tram line on foot.

How to Buy Tickets and Use the Contactless Payment System

This is where Sofia’s transport system changed most significantly in recent years, and where many older travel guides are now completely wrong.

Single paper tickets still exist and are sold at metro station ticket windows, vending machines, and from some kiosk shops near major stops. A single ride costs 1.60 BGN (approximately €0.82 / $0.88). You validate paper tickets at the yellow machines before boarding trams and buses, or at the turnstiles for the metro.

The Sofia Card / Urban Card (Градска карта) is a reloadable contactless smart card. You buy the card itself for a small deposit (2 BGN / ~€1), then top it up with credit. Single rides deducted from the card cost the same as paper tickets, but day passes and multi-ride bundles are much cheaper. A 10-ride bundle loaded onto the card costs 13 BGN (~€6.65).

Contactless bank card and mobile payment was introduced on the metro in 2023 and expanded to trams and most major bus routes by late 2025. In 2026, you can tap your Visa, Mastercard, or Apple/Google Pay at metro turnstiles across all three lines and at validators on most trams and trolleybuses. The system charges 1.60 BGN per tap, or recognises a daily cap of 8 BGN (~€4.09) — after that, further taps on the same card that day are free. This daily cap system makes contactless bank cards genuinely competitive with the Urban Card for short visits.

Who still needs to buy paper tickets? Only travellers paying with cash or those whose bank cards don’t support contactless. If you’re arriving for more than three or four days, picking up an Urban Card saves minor friction. If you’re here for a weekend, your contactless bank card is all you need.

Ticket inspection does happen — plain-clothes inspectors work both the metro and surface network. Fines for travelling without a valid ticket are 40 BGN (~€20.45). It’s not a gamble worth taking.

Navigating Sofia Airport by Public Transport

Sofia Airport (SOF) received significant terminal upgrades ahead of Schengen land border integration in 2025, and the public transport connections have become genuinely straightforward.

Metro Line 2 (M2) is the default choice. The metro station sits directly beneath Terminal 2 — follow the clearly marked underground signs from the arrivals hall. The journey to Serdika (city centre) costs 1.60 BGN and takes about 20 minutes. Trains run every 5–8 minutes during daytime hours. Terminal 1 users need to take the free inter-terminal shuttle bus first, which takes about 5 minutes.

Bus 84 connects Terminal 2 with the Mladost metro stations (on M2), running parallel to the metro. It’s slower and less convenient than the metro for most destinations, but useful if you’re heading to the Business Park or Mladost area specifically.

Night transport: The metro stops just after midnight. If you land after that, Bus N5 runs a night route between the airport and the city centre (Orlov Most). It runs hourly. Alternatively, a metered taxi from the airport to the city centre at night costs 15–25 BGN (~€7.67–€12.78) depending on your destination — more on taxis below.

One practical note: the airport has an official taxi rank outside Terminal 2 arrivals. Only use taxis from this rank or ordered via app. Unofficial drivers who approach you inside the terminal quote prices that are consistently three to four times higher.

2026 Budget Reality — What Public Transport Actually Costs

Sofia remains one of the most affordable capitals in Europe for getting around. Here’s an honest breakdown of what transport costs in 2026.

• Single metro/tram/bus ride: 1.60 BGN (~€0.82 / $0.88)
• 10-ride bundle (Urban Card): 13 BGN (~€6.65 / $7.15)
• 1-day pass (Urban Card): 4 BGN (~€2.05 / $2.20)
• 3-day pass (Urban Card): 10 BGN (~€5.11 / $5.50)
• 7-day pass (Urban Card): 18 BGN (~€9.20 / $9.90)
• Monthly pass (residents): 55 BGN (~€28.12 / $30.25)
• Contactless daily cap (bank card): 8 BGN (~€4.09 / $4.40)
• Airport to centre by metro: 1.60 BGN (~€0.82)

Budget tier (1–3 days): Use contactless bank card payment. You’ll hit the daily cap most days, meaning your transport for the entire day costs 8 BGN. For a three-day visit, budget around 24–30 BGN (~€12–15) total for all transport including the airport connection.

Mid-range tier (4–7 days): Buy an Urban Card on arrival (available at metro station ticket windows) and load a 7-day pass. At 18 BGN for unlimited rides across metro, tram, trolleybus, and city bus, this is exceptional value. You’ll carry the card and forget about fares entirely.

Comfortable tier (longer stays or convenience-focused): Combine an Urban Card for public transport with occasional ride-hailing for late nights or trips with heavy luggage. Budget roughly 18 BGN per week for public transport plus 30–50 BGN per week for 3–4 Bolt or Yandex trips.

Practical Tips for Getting Around Without Getting Lost

Sofia’s street grid looks logical on a map and feels slightly less logical when you’re standing on a boulevard trying to find the right stop. These are the things experienced users of the system know that first-timers typically don’t.

Stop names and numbering: Each stop in Sofia has an official code number — four digits displayed on the stop pole. These codes feed directly into the official Sofia Urban Mobility Centre app (СУMC / SUMC), which shows real-time departures for that exact stop. Download it before you arrive. Google Maps is also well-synced with Sofia’s GTFS data in 2026 and works reliably.

Direction matters more than you think: Tram and bus stops for opposite directions are often on different streets or significantly displaced from each other. At major intersections, check you’re on the correct side of the road before waiting.

The centre is walkable: The distance between NDK, Vitosha Boulevard, the Largo (the three-building communist-era ensemble around Serdika), the Banya Bashi Mosque, and the Women’s Market is small enough to walk comfortably. The metro and trams earn their value for reaching neighbourhoods beyond the centre — Lozenets, Studentski Grad, Lyulin, Mladost.

Night routes: Sofia has nine designated night bus routes (prefixed with N) that cover the main corridors between midnight and 05:30. They run roughly every 30–60 minutes. Fares are the same as daytime. The routes radiate from the city centre, and stops are marked on the Gradski Transport website.

Accessibility: All metro stations on M3 are fully accessible with lifts. M1 and M2 have mixed coverage — around half of stations have working lifts as of early 2026, with ongoing retrofit work scheduled through 2027. Most low-floor trams on the central routes were replaced with newer Škoda models in 2024–2025, making boarding easier at marked accessible stops.

When Public Transport Doesn’t Cut It — Taxis and Ride-Hailing

There are times when a private vehicle makes more sense: late-night arrivals, trips with bulky luggage, reaching places like Vitosha Nature Park’s upper trails, or simply when you’re tired and the next tram is 12 minutes away.

Ride-hailing apps are the safest and most transparent option. Bolt is the dominant platform in Sofia in 2026, with widespread driver availability and consistent pricing. Yandex Go also operates and is sometimes cheaper at off-peak times. Both show the fare upfront, accept in-app card payment, and give you a name and plate number before the car arrives. A typical cross-city trip (say, Mladost to Lozenets) costs 8–14 BGN (~€4–7).

Street taxis are legal and generally fine if you use metered companies. Look for taxis displaying the company name, phone number, and per-kilometre rate on the door. The standard metered rate in 2026 is 0.99–1.19 BGN per kilometre during the day and 1.29–1.49 BGN at night. OK Supertrans (tel: 02 973 2121) and Yellow Taxi (tel: 02 9119 119) are the most established companies. Always confirm the meter is running before you move.

Avoid: unmarked vehicles, drivers who approach you at tourist sites or the airport departures zone, and any driver who quotes a flat rate without showing you a published tariff card. These situations almost invariably end in a dispute over an inflated fare.

For trips to places like Boyana, Dragalevtsi, or the Vitosha foothills where buses are infrequent, a Bolt ride is often the cleanest solution — expect to pay 12–18 BGN (~€6–9) from the centre, and the app gives you the number before you commit.

One more sensory detail worth filing away: in winter, the hiss of tram doors opening at a central stop and the rush of warm air from inside the carriage is one of Sofia’s more welcoming small pleasures when the temperature drops below zero. The trams are heated. The platforms are not.

Frequently Asked Questions

Can I use my contactless bank card on all Sofia public transport in 2026?

Yes, across all three metro lines and most trams and trolleybuses. Some outer-district bus routes still require a paper ticket or Urban Card. The contactless daily cap of 8 BGN means unlimited city travel for the price of five standard single tickets — making a bank card the easiest option for short visits.

How do I get from Sofia Airport to the city centre cheaply?

Take Metro Line 2 (M2) from the station beneath Terminal 2. It costs 1.60 BGN (~€0.82), runs every 5–8 minutes during the day, and reaches central Serdika station in about 20 minutes. After midnight, use Night Bus N5 or a metered taxi or ride-hailing app instead.

Is Sofia’s public transport safe to use at night?

Generally yes. The metro is safe until it closes just after midnight. Night bus routes operate after that but are less frequent. The main risk on night buses is petty theft in crowded conditions — keep bags in front of you. For late-night travel, Bolt is a practical and well-priced alternative to public transport.

Do Sofia buses and trams announce stops in English?

Newer vehicles on major routes have electronic displays and audio announcements in Bulgarian, with some English-language signage. Older vehicles show nothing. The Moovit app and Google Maps both track your position in real time and alert you when your stop is approaching — use either app as your stop-tracking tool regardless of vehicle age.

Is a weekly transport pass worth buying for a 5–7 day visit to Sofia?

Yes, clearly. A 7-day Urban Card pass costs 18 BGN (~€9.20) and covers unlimited rides on metro, trams, trolleybuses, and city buses. If you’re making three or more journeys per day — which is easy in an active city visit — you’ll recover the cost within the first two days. Buy the card and load the pass at any metro station ticket window.
