A spokeswoman said demand for the Park In Progress Tours was so strong, the London Legacy Development Corporation had announced more dates, extending the tours until 23 June. This is exactly one month before the first official opening.
The visit includes a site briefing and a trip to the 80m-high ArcelorMittal Orbit viewing platforms where there is a new interactive experience telling the story of the site. Hundreds of local residents saw the park for a free preview just before Easter.
"In the coming months whole sections of the Park will be transformed with new cafes, community centres and gardens," said a spokesman. "The ArcelorMittal Orbit offers unique 360 degree views of the London skyline including St Paul’s Cathedral and Canary Wharf.
"The Olympic site is changing so rapidly that no two visits will be the same; already the riverside hockey arena has been dismantled, the largest McDonald’s in the world has gone and the temporary seating stands on the aquatics centre are being taken down.
