Wormwood Scrubs Park
Time Out says
A 200 acre park – the largest open space in the Hammersmith and Fulham borough – with myriad facilities. Not only does this park have sports pitches for football (nine large, seven small), rugby, Gaelic football and baseball, but there's a pony centre and a model aircraft runway. Plus the Linford Christie Outdoor Sports Centre, which contains astroturf and grass pitches, an athletics track, netball court and archery area. Impressive to say the least.
