Getting around Bulgaria: trains, buses, driving and domestic flights

Bulgaria's network is bus-first. Trains reach fewer places, run slower and sell tickets mainly at the station, while buses connect almost every town several times a day. The table below gives the working numbers for the routes most travellers actually use.

Start with the route, not the mode. If both ends are on the Sofia–Plovdiv–Burgas or Sofia–Veliko Tarnovo corridors, the bus is almost always the answer: more departures, similar or shorter journey times, and no need to reach a station early. Buy at the counter or from the driver (check); seats on popular afternoon services can fill in summer.

For the train, treat it as an experience rather than transport. BDZ fares are low and the mountain sections are the reason to ride: the narrow-gauge line through the Rhodopes and the overnight service to Varna are the two that travellers plan around. Expect older carriages, delays and limited English signage, and buy at the station rather than relying on an app.

A car changes what you can see. Rila Monastery, the Rhodope villages and Pirin are awkward or impossible by public transport in a day. Rent in Sofia or Plovdiv, add a vignette for motorway driving, and budget more time than the map suggests: mountain roads are slow and overtaking is aggressive.

Flying makes sense in one situation: Sofia to the Black Sea in summer, when 55 minutes replaces a 6–8 hour bus or train. Frequencies are low, so book ahead and check the season.

Inside cities, use the metro in Sofia (contactless card at the gate or a ticket), metered taxis or ride apps elsewhere. Posted rates on taxi windows vary, and unmarked cars overcharge; book through an app or a marked rank.

The main trap is assuming the train will be quicker because it looks direct. On the Sofia–Plovdiv and Sofia–Varna corridors it is not, and stations are often further from the centre than bus stops. The second trap is Sofia's two adjacent bus terminals: Central and Serdika are next to each other but handle different companies, so confirm which one before you set off with luggage.

Driving brings its own rules. A vignette is required for motorways and many main roads, and mountain routes take far longer than the distance suggests. Coastal resort businesses shut from October to May (check), which can affect services along the Black Sea.

Museums commonly close on Monday, and village churches open irregularly, so a car day built around one small site can fail. Have a second stop in mind. Tap water is safe in most cities and mountain spring taps are common, so refilling is easy on road trips.
