The largest park in Bucharest borders the city to the north, and much of its area is taken up by the 74-hectare Herăstrău Lake.
On the Colentina River, this large body of water is partly man-made having been formed when riverside marshes were drained in the 1930s.
The lake has a six-kilometre perimeter path favoured by joggers in summer, and in this season you can rent a bike near the main entrance or take a boat trip from the jetty on the south shore.
