Budapest's best views divide into two distinct categories determined by which side of the Danube you're on. From Pest — the flat eastern bank where most of the hotels, restaurants, and civic life concentrate — the view looks west across the river to the Buda Castle District and Gellért Hill. The Parliament building on the Pest side, one of the largest legislative buildings in the world (finished 1904), dominates the northern river view and is best appreciated from the Buda bank — the composition of the neo-Gothic building reflected in the Danube, particularly at blue hour before dawn and again at dusk, is the definitive Budapest image.
From Buda — the hilly western bank of the castle, the Fisherman's Bastion, and the Gellért Hill — the view reverses to the Pest skyline, the Parliament dome, and the infinity of the Great Hungarian Plain stretching east. The Fisherman's Bastion (Halászbástya), a neo-Romanesque terrace on the castle plateau, provides the most photographed Budapest view of all: the Parliament building directly across the river, framed by the Bastion's turrets and colonnades, with the Chain Bridge and the Elizabeth Bridge visible downstream. This view is experienced by millions and still retains the ability to stop you in your tracks.
The Citadel on Gellért Hill, the highest point in Budapest proper at 235 meters, provides the most complete panoramic view — all of Pest spread east to the horizon, all of Buda's hills arrayed behind, the Danube's great bend visible both north and south, and on clear days the distant Pilis Mountains 30km away. Several luxury hotels are built into the Gellért Hill's lower slopes with terrace restaurants facing this view.
Chain Bridge (Széchenyi Lánchíd), Budapest's most beloved structure (opened 1849, the first permanent bridge between Buda and Pest), frames the Buda Castle perfectly when viewed from the Pest embankment. The Danube Promenade (Dunakorzó) between the Chain Bridge and Elizabeth Bridge is Budapest's most atmospheric walking route at any time of day — lined with hotels whose terrace restaurants face the Buda bank with unobstructed views.
The city's thermal bath culture adds a dimension to Budapest's views — Széchenyi baths in City Park and Gellért baths in the Art Nouveau complex at the Gellért Hotel's base offer architectural views from within the baths themselves. The Gellért Hotel's thermal pool, with its barrel-vaulted glass ceiling and the terraced garden above the Danube, is an extraordinary architectural experience that combines bathing with a riverside view.
