Orientation is not a big problem in Budapest. The river Danube splits the city into two areas: Buda and Pest. Aside from the very center, the city's structure is quite logical. Landmarks in Buda as the Royal Castle or Citadella Castle also help you to find your way. Besides the Danube itself, the best reference points for orienting yourself are the bridges crossing the river. From North to South, they are:

• Árpád Bridge (Árpád híd), A modern bridge linking to Northern Margaret Island. The longest bridge in Budapest at 973 meters.
• Margaret Bridge (Margit híd), Easily identified thanks to its distinctive shape: it makes an approximately 35 degree turn half way across, at the southern tip of Margaret Island. Trams 4 and 6 cross the Danube here.
• Chain Bridge (Széchenyi lánchíd), Completed in 1849, the oldest, arguably most beautiful and certainly the most photographed of Budapest's bridges, floodlit at night.
• Elisabeth Bridge (Erzsébet híd), Completed in 1903. Its original chain structure was destroyed in World War II, and was eventually substituted by a modern cable bridge opened in 1964.
• Liberty Bridge (Szabadság híd), Elegant but simple, opened in 1896; it connects the Gellért Baths (Gellért fürdő) in Buda with the Great Market Hall (Nagyvásárcsarnok) in Pest. Recently renovated.
• Petőfi Bridge (Petőfi híd), For a long time the southernmost bridge, it links the inner ring road (Nagykörút) of Pest with Buda.
• Lágymányosi Bridge (Lágymányosi híd), The newest bridge in Budapest, with modern architecture and a spectacular lighting system where mirrors reflect the beam of the upward facing floodlights. Built very next to a railway bridge on its southern side.
