Hyde Park Area Guide
The park is divided in two by the Serpentine. The park is contiguous with Kensington Gardens; although often still assumed to be part of Hyde Park, Kensington Gardens has been technically separate since 1728, when Queen Caroline made a division between the two. Hyde Park covers 142 hectares (350 acres) and Kensington Gardens covers 111 hectares (275 acres), giving an overall area of 253 hectares (625 acres), making the combined area larger than the Principality of Monaco (196 ha/484 acres), though smaller than New York City's Central Park (341 ha/843 acres). To the southeast, outside the park, is Hyde Park Corner. Although, during daylight, the two parks merge seamlessly into each other, Kensington Gardens closes at dusk but Hyde Park remains open throughout the year from 5 am until midnight.
Hyde Park is the largest of four parks which form a chain from the entrance of Kensington Palace through Kensington Gardens and Hyde Park, via Hyde Park Corner and Green Park (19 hectares), past the main entrance to Buckingham Palace and then on through through Saint James's Park (23 hectares) to Horse Guards Parade in Whitehall.
