The Olympic Park is set to reopen in phases to the public from July 27 2013 - exactly a year after the opening of the London 2012 Olympics.
By then the newly-named Queen Elizabeth Olympic Park will have to start making its ambitions of becoming a new visitor destination and community park unlike any other in the UK a reality.
Transformation of the 560-acre Olympic site in Stratford, east London, is set to take 18 months from October 2012, the London Legacy Development Corporation (LLDC) said.
The North Park, a nature-themed community sector and playground also including the 7,500 multi-use sport, entertainment and community arena, will be the first area to reopen in July 2013.
The east London boroughs of Hackney, Tower Hamlets and Waltham Forest will all have entrances to the North Park and visitors could also walk there through Eton Manor.
The rest of the North Park, including the Lee Valley VeloPark and more visitor access points, is set to open at the end of 2013.
The South Plaza, sitting between the Olympic Stadium, Aquatics Centre and the ArcelorMittal Orbit, is set to open in Easter 2014.
At this point visitors will have access to the whole of the Park.
New entrances will open via Westfield shopping centre and Stratford High Street in Newham.
Planners see this area as tree-lined promenades which connect spaces that can be used in a variety of ways including for cultural programmes, pop up street food stalls and community events.
Structures used during the Games, such as temporary venues, bridges, walkways and roads, will be stripped out during the transformation.
The closure is also when the Park will be connected to the surrounding area with new roads, cycle and foot paths.
Permanent venues, bridges and parklands will also be completed ready for residents' and visitors' everyday use during this time.
LLDC chief executive Andrew Altman said: "London's Olympic Legacy was rooted in the creation of the Queen Elizabeth Olympic Park - a place that will become one of the most thriving parts of London. The creation of thousands of new homes and jobs will bring huge benefits to the area.
"The transformation will take the Park from an Olympic site, to a new piece of London that's owned and shaped by the community in and around it.
"Above all, the Park will create a place of practical benefit for the surrounding community - a place to take your children swimming at weekends, go to school, walk your dog or go to a festival in the summer."
