Sofia Airport to City Center: Your Complete Transport Guide

Bulgaria joined the Schengen Area’s land border zone in January 2025, which means the airport experience at Sofia (SOF) has shifted noticeably since 2024. Passport queues now move differently, new electronic systems register your biometrics on entry, and there is one more authorization — ETIAS — that many travelers have not yet heard of. Layer on top of that the practical chaos of figuring out how to reach the city center after a long flight, and it is easy to see why Sofia Airport confuses first-time arrivals. This guide walks you through everything in order: entry rules, airport procedures, and every transport option from the terminal door to your hotel.

Bulgaria Entry Requirements in 2026

Bulgaria has been a full Schengen member since January 1, 2025, with land, air, and sea borders all operating under standard Schengen rules. That single fact changes the entry experience for almost every nationality.

Who Does Not Need a Visa

EU, EEA (Iceland, Liechtenstein, Norway), and Swiss citizens enter with a valid national ID card or passport — no visa, no additional authorization required. Citizens of many non-EU countries are also visa-exempt for stays up to 90 days within any 180-day period. The list includes:

• North America: United States, Canada, Mexico
• Oceania: Australia, New Zealand, and most Pacific island nations
• Asia: Japan, South Korea, Singapore, Malaysia, Brunei, Israel, UAE, Qatar, Hong Kong SAR, Macao SAR, Taiwan (passport must contain identity card number)
• South America: Argentina, Brazil, Chile, Colombia, and most of the region
• Europe (non-EU): United Kingdom, Albania, Georgia, Montenegro, Serbia, Ukraine (biometric passports only), and others
• Other: Mauritius, Seychelles

ETIAS: The Step Most Travelers Miss

From mid-2025 onwards, most visa-exempt non-EU nationals must obtain ETIAS (European Travel Information and Authorisation System) authorization before traveling to any Schengen country, including Bulgaria. This is not a visa. Think of it like the US ESTA or Canadian eTA — an online pre-screening that takes minutes to complete. The cost is €7 (approximately 13.70 BGN), and approval is valid for three years or until your passport expires, whichever comes first. Apply at the official ETIAS website before you book flights. EU, EEA, and Swiss citizens are exempt from ETIAS entirely.

Who Still Needs a Schengen Visa

Citizens of countries not on the visa-exempt list must apply for a Schengen C visa at a Bulgarian embassy or consulate before traveling. The standard fee is €80 (approximately 156.46 BGN) for adults, with reduced rates for certain categories such as children. Check the Bulgarian Ministry of Foreign Affairs website at mfa.bg for the full country list and application requirements.

Navigating Sofia Airport: What Happens Before You Exit

Sofia Airport has two terminals. Most international and intercontinental flights arrive at Terminal 2, which has direct metro access. Low-cost carriers — including Wizz Air and Ryanair on many routes — often use Terminal 1. A free green shuttle bus connects Terminal 1 to Terminal 2, running every 15 to 20 minutes with a travel time of 5 to 8 minutes. Do not pay for this shuttle; it is complimentary.

Passport Control

After disembarking, follow signs to passport control. EU, EEA, and Swiss citizens use automated e-gates or dedicated fast-track lanes — the process is quick. Non-EU travelers queue at the standard lanes. Your passport must be valid for at least three months beyond your intended departure date, issued within the last ten years, and have at least two blank pages.

Since late 2024, the EU’s Entry/Exit System (EES) has been operational. On your first entry into the Schengen Area, border officers will collect your fingerprints and a facial image. This replaces the old manual passport stamp. It adds a minute or two to processing but is straightforward — simply follow the officer’s instructions.

Baggage and Customs

After passport control, collect your bags from the carousel indicated on the monitors. Then pass through customs. Use the green channel if you have nothing to declare. Use the red channel if you are carrying goods to declare — this includes cash or monetary instruments exceeding €10,000. Standard EU customs rules apply throughout.

Metro: The Fastest Way Into the City

Metro Line 4 (M4, the Orange Line) runs directly from Terminal 2 into the metro network. To reach the main city center, you will need one transfer:

1. Follow signs marked Метро / Metro from the arrivals hall at Terminal 2 — the station is on the ground floor.
2. Buy a ticket, load your Sofia City Card, or tap a contactless bank card at the gate.
3. Board the M4 (Orange Line) train toward the city.
4. Ride to Mladost 1 station.
5. Transfer to the M1 (Red Line) in the direction of Slivnitsa or Obelya.
6. Ride M1 to Serdika station — this is the heart of the city center, with exits near the main pedestrian zones.
7. If your hotel is further south on M2 (near NDK or Sofia University), change at Serdika to M2 (Blue Line).

Total travel time from Terminal 2 to Serdika is approximately 30 to 35 minutes including the transfer. The metro runs from roughly 05:00 to midnight. Peak-hour frequency is every 7 to 8 minutes; off-peak and weekends, every 10 to 15 minutes.

Fares and Tickets

• Single journey: 2.00 BGN (€1.02) — valid across the whole journey including transfers, as long as you do not exit the paid zone
• 24-hour day pass: 4.50 BGN (€2.30) — unlimited travel on all Sofia public transport for 24 hours
• 72-hour pass: 12.00 BGN (€6.14) — unlimited travel for three days
• Sofia City Card (reusable electronic card): 3.00 BGN (€1.53) for the physical card, then top up with credit or a pass

Since late 2024, most metro gates accept contactless bank cards (Visa, Mastercard) and mobile payments (Apple Pay, Google Pay) directly at the turnstile. Each tap deducts a single journey fare. If you are only making one trip and your card works abroad, this is the easiest approach — no machine queues, no coins needed.

Bus Lines 84 and 184: The Budget-Friendly Alternative

Two bus lines connect the airport to the city center, and both charge the same single-journey fare as the metro. The trade-off is time — buses are slower when traffic is heavy, particularly during morning and evening rush hours.

• Bus 84: Runs from Terminal 2 to Sofia University “St. Kliment Ohridski” station and continues to General Gurko Street in the center.
• Bus 184: Covers both Terminal 1 and Terminal 2, also heading to Sofia University station and General Gurko Street.

Both lines operate from approximately 05:00 to 23:30, with buses running every 15 to 30 minutes. Travel time to the city center ranges from 35 to 50 minutes depending on traffic. The fare is 2.00 BGN (€1.02) per journey — same pricing as the metro, and the same day/multi-day passes are valid.

To buy a ticket: use the machines at bus stops near both terminals (cash and card accepted), buy from kiosks in the terminal, or simply tap a contactless bank card on the validator inside the bus. Buying from the driver is possible but not recommended — drivers rarely carry change and it slows boarding. Validate paper tickets using the orange machine inside the bus immediately after boarding.

Bus 184 is particularly useful if you land at Terminal 1 and have heavy luggage — it saves the shuttle-to-metro route and drops you closer to some hotel clusters near the center.

Taxis and Ride-Sharing: When You Want a Direct Ride

After an overnight flight, carrying two bags and hunting for a metro transfer is nobody’s idea of fun. That is when a taxi or Bolt ride earns its premium.

Official Taxis

Use only licensed taxis from the designated stands outside the terminals. The two reputable companies at Sofia Airport are Yellow! Taxi (Йелоу! Такси) and Green Taxi (Грийн Такси). Both operate metered fares with price lists visible on the rear passenger window. The meter should start immediately when the car moves.

A typical daytime trip from the airport to the city center costs 25 to 35 BGN (€12.78 to €17.90). Night rates (after 22:00) are slightly higher. The approximate per-kilometre rates are 1.20 to 1.40 BGN/km during the day and 1.40 to 1.60 BGN/km at night, with an initial flag fee of around 0.90 to 1.00 BGN.

Never accept offers from people approaching you inside the terminal. These unlicensed operators routinely charge three to five times the legitimate rate. Walk past them, follow signs for the taxi stand, and use the dispatcher booth if you are unsure which car to approach.

Both Yellow! Taxi and Green Taxi have official apps — useful for getting a fare estimate before you get in, booking from inside the terminal, and paying by card.

Bolt

Bolt is the dominant ride-hailing app in Sofia in 2026. Uber has not re-entered the Bulgarian market. Bolt fares from the airport to the city center typically run 20 to 30 BGN (€10.23 to €15.35), though surge pricing applies during peak hours or late at night. Download the app and set up payment before landing — the airport pick-up zone is clearly marked outside the arrivals exit. Travel time is the same as taxis: roughly 20 to 30 minutes depending on traffic.

Private Transfers, Shuttles, and Car Rental

Pre-Booked Private Transfers

Private airport transfers can be booked in advance through your hotel or a transfer company. The driver meets you inside the terminal with a name board, handles your luggage, and takes you directly to your accommodation. Prices start from 40 to 60 BGN (€20.45 to €30.68) for a standard car. Shared shuttle services exist at lower price points but add extra stops and waiting time.

This option makes the most sense for groups of three or more, travelers with mobility needs, or anyone arriving very late at night when Bolt surge pricing can push costs up significantly.

Car Rental

Major international companies — Avis, Hertz, Europcar, Budget, Enterprise, Sixt — plus local operators like Top Rent A Car all have desks at Terminal 2. Book well in advance during summer (June to August) and ski season (December to February) as availability drops fast. Non-EU license holders should carry an International Driving Permit (IDP). Sofia city traffic during morning and evening rush hours is genuinely heavy, and parking in the center is limited and paid. Car rental is better suited to travelers who plan to explore outside Sofia rather than those staying in the capital.

2026 Budget Reality: Full Cost Comparison

Here is a clear breakdown of what each option costs in 2026, so you can choose based on your budget and priorities:

• Budget — Metro or Bus: 2.00 BGN (€1.02) per single journey. A 24-hour pass at 4.50 BGN (€2.30) covers your return trip and any city travel on your first day. Total airport-to-center cost: under 5.00 BGN (€2.56).
• Mid-range — Bolt: 20 to 30 BGN (€10.23 to €15.35) depending on time of day and demand. No haggling, door-to-door, air-conditioned.
• Comfortable — Licensed Taxi: 25 to 35 BGN (€12.78 to €17.90) for a metered ride with a reputable company. Slightly more predictable than Bolt for fare estimation.
• Premium — Private Transfer: From 40 to 60 BGN (€20.45 to €30.68) for a pre-booked, meet-and-greet service. Best value for groups or heavy luggage.

Note that Bulgaria uses the Bulgarian lev (BGN) for all everyday transactions. Despite the lev being pegged to the euro at a fixed rate of €1 = 1.95583 BGN, Bulgaria does not use the euro in shops, transport, or restaurants. Always pay in BGN and withdraw BGN from ATMs at the airport or in the city rather than exchanging at airport counters, which typically offer worse rates. A1, Yettel (formerly Telenor), and Vivacom all have SIM card kiosks in the arrivals area at Terminal 2 if you need local data immediately upon landing.

Common Mistakes to Avoid at Sofia Airport

• Not applying for ETIAS before departure. From mid-2025, visa-exempt non-EU travelers who skip this step can be denied boarding by the airline. Apply online before booking flights.
• Arriving at Terminal 1 and assuming there is direct metro access. There is not. Take the free green shuttle to Terminal 2 first.
• Accepting taxi offers inside the terminal. These are almost always unlicensed operators. The official taxi stand is outside, not inside the building.
• Trying to pay in euros on the bus or metro. Only BGN is accepted on public transport. Contactless cards work fine — but the transaction settles in BGN.
• Buying currency at airport exchange desks. Rates are poor. Use an ATM in the arrivals hall and withdraw BGN directly.

Frequently Asked Questions

Do I need a visa to enter Bulgaria in 2026?

It depends on your nationality. Citizens of EU and EEA countries need only a valid ID or passport. Many other nationalities — including the US, UK, Canada, and Australia — are visa-exempt for up to 90 days but must obtain ETIAS authorization online before travel. Citizens of countries not on the exempt list require a Schengen C visa obtained before departure. Check mfa.bg for your specific country.

What is the cheapest way to get from Sofia Airport to the city center?

The metro and bus are both priced at 2.00 BGN (€1.02) for a single journey — the cheapest options by far. The metro (M4 from Terminal 2, transfer at Mladost 1 to M1, exit at Serdika) takes around 30 to 35 minutes. Bus 84 or 184 takes 35 to 50 minutes depending on traffic but covers both terminals.

Is Uber available at Sofia Airport?

No. Uber is not currently operating in Bulgaria. The dominant ride-hailing app is Bolt, which is widely used and reliable. Download the Bolt app before your flight, set up your payment method, and request a ride after exiting arrivals. Fares from the airport to the city center typically run 20 to 30 BGN (€10.23 to €15.35).

What documents do I need when arriving at Sofia Airport?

All travelers need a valid passport (valid at least three months beyond departure, issued within 10 years, with two blank pages). Visa-required travelers must also present their Schengen C visa. Visa-exempt non-EU nationals need ETIAS authorization from mid-2025. Since late 2024, the EU’s Entry/Exit System also collects biometric data (fingerprints and facial image) from non-EU/EEA travelers on first Schengen entry.

How do I get from Sofia Airport to Sofia Central Railway Station?

There is no direct train between the airport and the railway station. Take Metro Line 4 (M4) from Terminal 2 to Mladost 1, transfer to Metro Line 1 (M1) toward Obelya, and ride two stops past Serdika to Central Railway Station (Централна ЖП гара). Total journey time is approximately 35 to 40 minutes. BDZ train schedules are at bdz.bg.
