Getting Around Bulgaria: Buses, Trains, Cars and Flights

The verdict: buses first, trains for scenery, cars for mountains

Choose buses for point-to-point travel between cities, because they are frequent and generally the fastest surface option on the main routes. Choose trains when the fare matters more than an hour or two of your day and you want the slower, older-school experience of Bulgarian State Railways. Choose a car only when your list includes places that buses reach awkwardly or not at all, such as trailheads in the Rila Mountains and remote monasteries.

The trade-off is real on the busiest routes. Public transport across the country is inexpensive, but buses are usually quicker between major towns while trains stay punctual and cheap on the same corridors, so the choice comes down to time versus money.

Bulgaria's transport map in brief

Sofia is the hub for almost everything: the main bus station and central railway station sit close together, and the airport connects to the center by metro. From there, the corridors that matter for visitors run east to Plovdiv and on to Burgas and the Black Sea coast, north to Veliko Tarnovo, and northeast to Varna. Mountain access fans out from Sofia toward the Rila Mountains and from towns like Apriltsi into the Central Balkan range.

That shape means you rarely need a car for a city-and-coast itinerary, and you almost always want one for a mountains-and-monasteries itinerary. Plan the order of your stops around Sofia rather than zigzagging, and the transport problem mostly solves itself.

Intercity buses: the default choice

Coaches connect nearly every city and town, with multiple operators running out of Sofia Central Bus Station. On the most-traveled corridor, a Sofia–Plovdiv ticket runs about 20–25 BGN for a journey of roughly 1.5–2 hours, while Sofia to Varna or Burgas takes 4–6 hours and costs around 35–50 BGN depending on company and departure time.

Elsewhere the pattern holds: a Sofia–Varna bus costs around 20 EUR and takes about seven hours, and Varna–Plovdiv is in the 16–25 EUR range for a similar seven-hour ride. Sofia to Veliko Tarnovo should not cost more than 13–20 EUR and takes about three hours by bus, which is the fastest way to reach the old capital.

Practical friction is modest but worth knowing. Buy intercity tickets at the bus station at least an hour ahead on popular routes, or from the driver on rural services, and expect air conditioning and Wi-Fi as standard on many long-distance coaches.

Trains with Bulgarian State Railways: cheaper, slower, scenic

Bulgarian State Railways, known as BDZ, reaches most towns, keeps low fares and runs on time, and express and rapid services are the ones to book on main lines rather than the slow stopping trains. Long-distance and overnight trains have reasonably priced couchettes and sleepers, and expresses and many rapid trains require a seat reservation on top of your ticket.

The price advantage is clearest where the bus is fastest. Sofia to Veliko Tarnovo costs just 8–15 EUR by train but takes a little over four and a half hours against roughly three by bus, and Sofia–Plovdiv by second-class rail runs about 15–20 BGN over 2.5–3 hours. If you value the journey itself, the train is the better deal; if you value the afternoon, take the coach.

Booking has a quirk that catches people out. Station ticket offices sell tickets for the day of travel only, so on weekends and in summer buy in advance from a railway booking office if you want a seat, and specify a non-smoking carriage when you book.

Sofia public transport: metro, trams and trolleybuses

Sofia's metro is the backbone of the city system, with four lines linking neighborhoods, business districts and the airport. A single ride costs about 1.60 BGN, and tickets come from machines and kiosks or increasingly straight from a contactless bank card at the gates, which is the easiest option if you have just landed.

Trams and trolleybuses fill the gaps the metro leaves, priced similarly, and day or multi-day passes cut the cost if you plan several rides. Fares across the system are typically under 2 BGN, making city transport a rounding error in a Bulgarian budget.

Plovdiv, Varna and Burgas without a car

In Plovdiv, Varna and Burgas, city buses form the main network, with typical urban fares around 1.50–2.00 BGN per ride. Historic centers and seaside promenades are walkable, so you can usually treat public transport as a backup for the edge of town rather than a daily necessity.

Varna and Burgas both work as bases for the coast without a car, since intercity coaches connect them to Sofia and to each other. If your plan is largely beach time with a couple of city days, the bus network plus walking covers it and a rental adds cost without adding much. For the southern end of that stretch, read our Burgas trip guide before you commit to beach days there.

Airport transfers in Sofia, Varna, Burgas and Plovdiv

Sofia Airport is the main gateway, and Terminal 2 connects directly to the M4 metro line, reaching Serdika in central Sofia in about 20–25 minutes for 1.60 BGN per ticket. Local buses 84 and 184 also run to the center roughly every 15–30 minutes during the day for around 1.60–2.00 BGN.

At Varna and Burgas, public buses link the airport with the city center and main bus stations for roughly 2–3 BGN, while taxis to central hotels typically run 20–35 BGN. Plovdiv Airport has limited public transport, so a pre-booked transfer or taxi at 25–40 BGN into town is the practical choice.

Taxis and ride-hailing: meters, tariffs and the airport trap

Metered taxis are easy to find in Sofia, Plovdiv, Varna and Burgas, with tariffs starting around 1.00–1.50 BGN plus 1.00–1.50 BGN per kilometer in the daytime; a 5 km ride in central Sofia might cost 8–12 BGN depending on traffic. Ride-hailing apps including Bolt operate in the bigger cities, often at slightly lower prices with an upfront fare.

The airport is where people get caught. Official taxis display company names and prices on the windows, and you should avoid unmarked cars or drivers approaching you inside the terminal and confirm the meter is running before you set off.

Domestic flights: when flying beats the bus

Domestic routes are limited, which makes flying inconvenient for most itineraries, but it is affordable where it exists. A one-way Sofia–Varna ticket costs about 90–110 EUR and Sofia–Burgas about 100 EUR, so unless you are pressed for time the bus or train is the better use of money.

The calculus is simple: a flight saves most of a day relative to the seven-hour coach from Sofia to Varna, and costs several times as much. On a short trip with a fixed Black Sea booking, that trade can be worth it; on a two-week loop, it usually is not.

Driving in Bulgaria: rentals, vignettes and road rules

Driving is very doable for visitors comfortable with European roads and opens up mountains, monasteries and wine regions, but road conditions vary and a cautious style pays off. Compact rentals typically start around 60–90 BGN per day depending on season and insurance, you drive on the right, and seat belts are mandatory for everyone in the car.

Most highways and major roads require an electronic vignette for vehicles under 3.5 tonnes. Rental contracts often include it, but confirm with the agency and check the validity period, because fines for driving without one can be substantial. Posted limits are generally 50 km/h in cities, 90 km/h on open roads and 140 km/h on motorways, and the blood alcohol limit is 0.05%.

An International Driving Permit is worth carrying if your license is not in Latin script, since some rental companies ask for one regardless. Keep digital copies of your documents and expect potholes, narrow village roads and the occasional animal on rural routes.

Buses versus trains versus cars: a verdict by traveler type

City-hoppers doing Sofia, Plovdiv, Veliko Tarnovo and the coast should go bus-first and skip the car entirely; the coach network is fast and cheap and parking in the cities is a distraction. Budget travelers with time to spare should take the train on the Sofia–Plovdiv and Sofia–Veliko Tarnovo corridors, where the savings are clear and the scenery is the point.

Hikers, photographers and anyone with Rila Monastery or the Central Balkan range high on the list should rent a car for those days and use buses for the rest. Families with beach plans are usually best served by flying into Varna or Burgas and staying put, since the coast itself is compact.

Mountains and monasteries without a car

Rila Monastery is the classic case: it takes about two hours by car from Sofia, and without a vehicle the practical option is a guided day tour from the capital rather than stringing together rural buses. The same logic applies to trailheads in the Rila Mountains and the Central Balkan range, where services thin out away from the main roads.

If you would rather not drive, build your trip around towns that sit on bus and rail lines and book organized excursions for the dispersed sights. That keeps costs predictable and avoids the paperwork that comes with a rental.

Common mistakes that slow Bulgaria trips down

The most common error is assuming the train will be faster because it is cheaper, then losing an afternoon on a route the bus covers in three hours. The second is buying a rail ticket on the day at a station counter during summer weekends, when advance booking from a city booking office is the only reliable way to get a seat.

The third is renting a car for a city itinerary and then discovering that parking and the vignette add friction without adding freedom. Match the mode to the shape of the trip, and Bulgaria moves easily.

Plan Your Trip

Build your Bulgarian itinerary around the bus network first, add trains where the fare matters more than the hour, and reserve a car for the mountain days. That combination keeps costs low and still gets you to the places that make the country worth the trip.
