The Metró has three lines, including the yellow (M1), red (M2) and blue (M3) lines. It operates from 4.30 in the morning to 23.30, with trains every few minutes. A single ticket costs 320 Ft and a 10 ticket discount book costs 2800 Ft – these are also valid on the bus or tram on the whole length of the line for one uninterrupted trip. Get your tickets from underground stations, tobacconists, newsagents or vending machines, since you can’t buy them onboard. Alternatively, you can opt to buy the Budapest card, which gives you unlimited travel on the city’s public transport services. The card also entitles you to discount admission to a wide range of attractions in Budapest, including museums and monuments. If you’re staying for more than a weekend it offers good value for money.
