3 days in Budapest: itinerary

Budapest splits into Buda, the hilly west bank with Castle Hill and Gellért Hill, and Pest, the flat east bank with Parliament, the Basilica, Andrássy út and most hotels. Three days works because the two halves are 10–15 minutes apart by metro or tram across the river.

Build the plan around three anchors: one full day on Castle Hill and the Danube, one full day on the Pest side, and one slower day for a thermal bath plus whatever you skipped. Anything more ambitious, such as Esztergom or Lake Balaton, eats a whole day and belongs in a longer trip.

Budapest is cheaper than Vienna or Prague for the same standard of hotel and food. A mid-range double room in District V–VII runs a moderate nightly rate in 2026 terms, and a filling lunch of goulash or a market-hall plate costs a fraction of a Western European city. Public transport single tickets and 72-hour travel cards are the main fixed cost of the day.

Most museums open around mid-morning and close late afternoon, with one closing day a week, often Monday. Baths run longer, sometimes into the evening. Parliament tours sell out in summer, so book days ahead and bring the passport you used to book. On 15 March, 20 August, 23 October, 1 November and 24–26 December, shops close and some sights run holiday hours.

Budapest is the rail hub of Hungary, so every domestic route runs through it: Eger, Szeged, Pécs, Lake Balaton and the Danube Bend all connect from the main stations. If you are arriving from another European city, night and daytime trains from Vienna take roughly two and a half hours, and the airport sits about 30–40 minutes from the centre by the 100E bus or a taxi.

Within the city, the metro is fast and the trams along the Danube are the scenic option. Buy tickets from machines or apps before boarding; inspectors do check. From the airport, allow an hour door to door if you land at a busy time.
