FAQs about flying to Sofia

Sofia climate

Getting around Sofia

Sofia’s public transport network of buses, trolleys and trams reaches all corners of the city from early morning to late evening. Buy tickets from street kiosks. Fares are cheap, but one-day and multiple-day tickets will save you even more money. The metro doesn’t hit tourist attractions or hotels. Be prepared and travel with a map, and don’t be afraid to ask locals for help. Despite public transit system’s extensive coverage, stops aren’t well-marked and contain little if any information. For a bit more money, you can travel in a private minibus, which is faster than a regular bus. Don’t worry about buying tickets ahead of time, just pay the driver when you board. Calling for a taxi can get lost in translation. Most dispatches don’t speak English, but the fares are reasonable as long as you’re not overcharged. Make sure the meter is running and know where you’re going. Drivers expect you to know where you’re going and often need you to give directions. 

Don’t drive in Sofia. With public transport and taxis available, battling the horrible traffic isn’t worth it.
