Tourist Map of Budapest, Buda left, Danube middle, Pest right. Note bridge linked to an island (Margaret bridge/island) at top? The "great ring road" or körút leads from there all the way round to Petöfi bridge in the south. There is also a little ring road inside it that bounds the 5th district. Each administrational district of the city is has a different colour here. Budapest has 23 districts in all, with far more in Pest than Buda, so you can see this is really just the downtown area.
