The Queen Elizabeth Olympic Park in Stratford, east London, has opened to the public for the first time since it hosted the London 2012 Olympics and Paralympics.
Alongside venues for sport and the arts, London's newest park features interactive water fountains and an adventure playground.
Visitors can go up the 375ft-high (114.5m) ArcelorMittal Orbit tower.
It is the biggest park to be opened in London for a century and is almost the size of Hyde Park and Kensington Gardens combined, around 560 acres.
It is hoped the attraction will revitalise the neighbourhood and bring tourists to the area.
Visiting the park is free, although there will be charges for some of the attractions.
More than 10,000 new households are planned for the site by 2030.
Current attractions also include the Aquatics Centre and VeloPark, and future ventures are planned with the Victoria and Albert Museum (V&A) and University College London (UCL).
The 80,000-capacity Olympic Stadium will become the new home of West Ham United FC in 2016.
Queen Elizabeth Olympic Park - which acquired its name only after the Games to commemmorate the Diamond Jubilee - boasts 40 miles of waterways and 15 acres of woods, hedgerows and wildlife habitats.
Last week Prince Harry visited the park.
The prince said the site had been "brought to life" by the creativity people had shown.
Prince Harry and London Mayor Boris Johnson toured the site meeting schoolchildren and people behind its development.
The pair made their way across a rope bridge alongside local schoolchildren and took part in a mobility scheme bike ride with disabled people.
During the tour, Harry climbed on to a basket swing and had to hold on as a group of children pushed him as high as possible.
The park straddles four east London boroughs: Newham, Tower Hamlets, Hackney and Waltham Forest.
