Budapest is the capital and largest city of Hungary, home to about 1.7 million people on both banks of the Danube. It was formed in 1873 when Buda and Óbuda, on the hilly western bank, were united with Pest on the flat eastern side, and its river panorama, from Buda Castle to the Hungarian Parliament, has been a UNESCO World Heritage Site since 1987, extended in 2002 to include Andrássy Avenue.
Visitors come for the thermal baths fed by more than 100 geothermal springs, the grand 19th-century avenues, the old Jewish quarter and its ruin bars, and the views from Gellért Hill and the Fisherman's Bastion. Public transport is excellent and includes the M1 Millennium Underground of 1896, the first underground line on the European continent. Apartments in Pest's central districts suit city breaks and nightlife, while Buda's quieter streets suit families and longer stays, although local rules on short-term rentals now differ by district. The Danube Bend towns of Szentendre, Visegrád and Esztergom make easy day trips.
District V, Belváros-Lipótváros, the inner city on the Pest bank, holds the Parliament, St Stephen's Basilica and the Danube promenade and is the most central choice for a first visit. District VII, Erzsébetváros, covers the historic Jewish quarter of Pest, with the Dohány Street Synagogue and many ruin bars; it is the most densely populated district and lively late into the night, better for nightlife than for light sleepers. District VI, Terézváros, along Andrássy Avenue with the State Opera House and the Liszt Academy of Music, has banned short-term letting of flats since 1 January 2026, so check a listing's status carefully there.
Across the river, District I, the Castle District on Castle Hill, is quiet and historic, with Matthias Church and the Fisherman's Bastion, though its streets are steep and shops fewer. Other Buda neighbourhoods, below Gellért Hill and along the river, are residential and calm, good for families and long stays. Margaret Island, a park island largely closed to cars, is easy to reach from both banks.
The river panorama is the heart of Budapest. On the Buda side, Castle Hill carries Buda Castle, the historic palace of the Hungarian kings, now home to museums and the National Széchényi Library, along with the Matthias Church and the Fisherman's Bastion, built between 1895 and 1902, whose terraces look out over the whole city. To the south, Gellért Hill, 235 metres high, is topped by the Citadella, which the Habsburgs built after the revolution of 1848 and 1849.
On the Pest bank, the neo-Gothic Hungarian Parliament faces the river, and St Stephen's Basilica and the State Opera House are a short walk inland. The Széchenyi Chain Bridge, opened in 1849 as the first permanent bridge between Buda and Pest, links the two halves, and several other bridges cross within the city. Andrássy Avenue, with the Millennium Underground beneath it, leads to Heroes' Square and its Millenary Monument, flanked by the Museum of Fine Arts and the Kunsthalle, with City Park behind.
Budapest has been a spa destination since Roman times and has more than 100 medicinal geothermal springs. The Romans built baths in their military town, and the Ottoman Turks, who held Buda for about 150 years from 1541, constructed many prominent bathing houses. The best-known bath today is the Széchenyi Medicinal Bath in City Park, a vast neo-Baroque complex designed by Győző Czigler and opened in June 1913, supplied by two thermal springs at 74°C and 77°C.
Margaret Island, about 2.5 kilometres long and 500 metres wide in the middle of the Danube, is mostly covered by landscaped parks and is a favourite place to walk, run and relax. Since the 1980s car entry has been limited to a single bus line, taxis and service traffic. The island has the Palatinus open-air swimming complex and the 13th-century ruins of a Franciscan church and a Dominican convent. An apartment with a kitchen makes it easy to balance spa days with the city's markets and food.
The Romans turned an early Celtic settlement into Aquincum, which became the main city of the province of Pannonia Inferior in 106 AD; its remains lie in Óbuda, District III. In the Middle Ages Buda became a royal seat and its castle grew into a great Gothic palace, and after King Matthias Corvinus married Beatrice of Naples in 1476, Italian humanists, artists and craftsmen came to his court. The Ottomans took Buda in 1541 and ruled it for nearly 150 years, until its reconquest in 1686.
In 1849 the Chain Bridge opened as the first permanent link between Buda and Pest, and in 1873 Buda, Óbuda and Pest were united as Budapest. The new metropolis flourished in the following decades, adding its avenues, the Parliament and the underground railway of 1896. The city suffered heavily in the battle of 1945 and was the focus of the Hungarian Revolution of 1956, which began with a peaceful demonstration on 23 October demanding democratic reform.
North of the city, the Danube swings through a tight U-shaped curve near Visegrád known as the Danube Bend. Szentendre, a riverside town known for its museums, galleries and artists and for the Hungarian Open-air Museum, is linked to Batthyány tér in Budapest by a frequent suburban railway. Visegrád keeps the extensive ruins of a royal palace and a medieval citadel on a hill above the river, while Esztergom, about 46 kilometres north-west of Budapest on the river that forms the border with Slovakia, is crowned by its basilica, the largest church in Hungary, built between 1822 and 1869.
To the south-west, Lake Balaton, a freshwater lake in the Transdanubian region, is one of the country's leading holiday areas. Resorts such as Balatonfüred and the spa town of Hévíz developed early as retreats for the wealthy, and in the late 19th century landowners began building summer houses to rent to the middle class, the start of a holiday-home tradition that continues today.
Budapest Ferenc Liszt International Airport (BUD), renamed after the composer in 2011, lies about 16 kilometres south-east of the centre. Buses link it with the city, and from Terminal 2 the 200E bus runs to Ferihegy railway station, from which trains reach Nyugati station. Budapest has three main railway stations, Keleti, Nyugati and Déli, with domestic and international services.
The transport authority BKK operates four metro lines, including the historic M1 under Andrássy Avenue, suburban railway lines, dozens of tram lines, trolleybuses, hundreds of bus routes including night services, boat services and BuBi, a bicycle-sharing network. The metro and tram lines form the backbone of the system. The central districts are walkable, and the bridges make it easy to cross between Buda and Pest on foot. A car is not needed for a city stay; keep it for trips into the countryside.
Budapest has a climate on the border between humid temperate and humid continental, with warm to hot summers and chilly winters. The long summer, from May to mid-September, is warm or very warm, with sudden heavy showers, especially in May and June. Autumn, from mid-September to late October, brings little rain, long sunny days and moderate temperatures, and is often the most pleasant time to visit before temperatures drop abruptly in late October or early November.
Winter, from November to early March, can be cold, with little sunshine, fairly frequent snow and night-time lows of minus 10°C that are not uncommon between mid-December and mid-February, a good season for the baths, museums and concerts. Spring is changeable in March and April, though days are often agreeable and nights fresh. The city averages around 2,000 hours of sunshine and about 84 days with precipitation a year.
District V on the Pest bank is the most central, near the Parliament and the river. District VII suits nightlife lovers, and the Castle District and other Buda neighbourhoods are quieter. District VI has banned short-term letting of flats since 1 January 2026, so check a listing's status before booking there.
Mid-September to late October offers little rain, sunny days and moderate temperatures. May to mid-September is warm or very warm, with occasional heavy showers. Winter is cold and grey, with night frosts down to minus 10°C, but it is a good time for the thermal baths and museums.
Budapest Ferenc Liszt International Airport (BUD) is about 16 kilometres south-east of the centre. Buses run into the city, and the 200E bus connects Terminal 2 with Ferihegy railway station, from which trains go to Nyugati station. Taxis are also available.
Three days cover Castle Hill, the Parliament, St Stephen's Basilica, Andrássy Avenue, the Jewish quarter and a thermal bath. With four or five days you can add Margaret Island, Gellért Hill and a day trip to Szentendre, Visegrád or Esztergom on the Danube Bend.
Hungary uses the forint (HUF), not the euro. Prices in Budapest are normally given in forints, so it is worth carrying some local cash and checking which currency you are being charged in before you pay.
No. Four metro lines, dozens of tram lines, buses, trolleybuses, boats and BuBi bicycles cover the city, and the centre is walkable. Suburban trains reach Szentendre, and a car is only useful for touring Lake Balaton or the countryside.
Rules are tight and changing. Under a national moratorium, no new private accommodation can be registered in Budapest until 31 December 2026, though places already registered may keep operating. District VI has banned short-term letting of flats since 1 January 2026, and other districts may set their own limits. Check the current rules for each district.
Yes. Margaret Island's parks and the Palatinus open-air pools, City Park, the Budapest Zoo, boat services on the Danube and the walk up Castle Hill appeal to children. A flat in a calmer Buda neighbourhood or District V gives space away from the nightlife streets.
