Budapest - Geography

Geography

The 525 km2 area of Budapest lies in central Hungary surrounded by settlements of the agglomeration in Pest county. The capital extends 25 and 29 kilometers in the north-south, east-west direction respectively. The Danube enters the city from the north; later it encircles two islands, Óbuda Island and Margaret Island. The third island Csepel Island is the largest of the Budapest Danube islands, however only its northernmost tip is within city limits. The river that separates the two parts of the city is only 230 m (755 ft) wide at its narrowest point in Budapest. Pest lies on the flat terrain of the Great Plain while Buda is rather hilly. Pest's terrain rises with a slight eastward gradient, so the easternmost parts of the city lie at the same altitude as Buda's smallest hills, notably Gellért Hill and Castle Hill. The Buda hills consist mainly of limestone and dolomite, the water created speleothems, the most famous ones being the Pálvölgyi cave and the Szemlőhegyi cave. The hills were formed in the Triassic Era. The highest point of the hills and of Budapest is János hill, at 527 metres (1,729 ft) above sea level. The lowest point is the line of the Danube which is 96 metres (315 ft) above sea level. The forests of Buda hills are environmentally protected.
