How to get to Bulgaria: airports, flights and border crossings

Sofia is the default. It takes the widest range of direct flights from Western Europe and the Gulf, and the metro reaches the terminal, so you can be at a hotel near the centre for the price of a ticket rather than a taxi. If your trip is Sofia, Plovdiv, Rila and Veliko Tarnovo, fly in and out of Sofia and move by bus or car.

Varna and Burgas are the coast airports. Varna suits the northern coast and the Sea Garden; Burgas is closer to Nesebar, Sozopol and Primorsko. Both are busy from June to September with charter and low-cost routes, and thin out sharply outside the season. Flying into one and out of the other is a good way to cross the country without backtracking.

Plovdiv has a small airport with mostly low-cost and seasonal services. It is useful if a cheap fare lines up, but do not build a trip around it. If you are arriving from Greece or Turkey by land, you may not need an airport at all.

From the UK and Ireland, direct flights to Sofia run from London, and seasonal routes serve the coast. Expect roughly 3 to 3.5 hours. From Western Europe, direct flights are common and take 2 to 3 hours. From the US and Canada there are no nonstop flights to Bulgaria, so you connect through a European hub — London, Frankfurt, Munich, Vienna, Amsterdam, Istanbul or Warsaw — and the total is usually 12 to 16 hours including the stop.

From Australia and New Zealand, expect one or two stops through the Gulf, Istanbul or a European hub, with total travel of 22 to 30 hours. Fares swing a lot by season: July and August on the coast and the Christmas and New Year weeks are the most expensive, while late spring and early autumn are usually cheaper and quieter.

Book the connection as one ticket where you can. A self-transfer through a hub means a delay on the first leg can cost you the second.

Bulgaria borders Greece, Turkey, Serbia, North Macedonia and Romania. Buses connect Sofia with Thessaloniki, Istanbul, Skopje, Belgrade and Bucharest, and the Danube bridges at Ruse and Vidin link to Romania. Crossing by bus is usually the cheapest option and the easiest if you do not want to drive. Carry your passport, since checks at these borders are normal.

Trains are slower and less frequent than buses, but the route from Romania over the Danube and the line toward Istanbul are the classic ones. If you are coming from Greece, the bus from Thessaloniki to Sofia is the practical choice.

By sea, ferries have linked Turkish Black Sea ports with Burgas and Varna in some seasons, but services change and can stop entirely. Check current schedules before you plan a sea arrival; do not assume a ferry is running.

Bulgaria uses the euro from 1 January 2026, so you can arrive with euros and skip a currency exchange. Cards work in hotels, larger restaurants and supermarkets; keep some cash for small cafés, markets and rural buses. Buy a local SIM or eSIM if you want data from the moment you land — EU roaming rules apply to EU SIMs, but not to most non-EU ones.

Sofia airport is small and quick to clear outside peak charter times. The metro runs to the centre and is the cheapest way in; taxis are metered, and you should use an official rank rather than a driver who approaches you inside the terminal. Varna and Burgas airports are close to their city centres and to the coast resorts.

Check your entry documents before booking. Bulgaria applies Schengen rules, and passport validity and visa requirements depend on your nationality, so confirm the current rules for your passport rather than relying on older advice.

Book summer coast flights and Christmas travel early — those are the peak windows and fares climb. For Sofia, spring and autumn are cheaper and the city is at its best, so you have more flexibility. If your dates are fixed around a holiday, check the Bulgarian public holidays, since some services thin out and prices rise.

For land arrivals, buses rarely need booking far ahead except on holiday weekends and the Thessaloniki and Istanbul routes in summer. If you are crossing by car, allow extra time at the Turkish border in August, when queues are longest.

The most common one is booking a coast airport for a Sofia-centred trip, or the reverse, and losing a day to a long transfer. Match the airport to the part of the country you are actually visiting. The second is assuming a ferry from Turkey will run; services are seasonal and change, so confirm before you commit.

The third is treating Bulgaria as a euro-free Balkan country. It adopted the euro on 1 January 2026, so old advice about changing lev is out of date. Finally, do not leave passport checks to chance at land borders — carry your document and expect a stop.
