Public Transport Budapest
Urban transport is well developed in Hungary, with efficient bus and, in many cities and towns, trolleybus services. Budapest, Szeged, Miskolc and Debrecen also have trams, and there's an extensive metro system and suburban railway known as the HÉV in the capital.
You'll probably make extensive use of public transport in Budapest but little in provincial towns and cities: with very few exceptions, most places are quite manageable on foot, and bus services are not all that frequent except in the largest settlements. Generally, city buses meet incoming long-distance trains; hop onto anything standing outside when you arrive, and you'll get close to the city centre.
You must purchase transport tickets at newsstands or ticket windows beforehand and validate them once aboard. Traveling without ticket is an offence; you'll be put off and fined on the spot. Don't try to argue; the inspector has heard it all before.
