London Fields is one of Hackney's liveliest open spaces, with broad lawns, mature trees, a heated lido, and a steady weekend crowd from the surrounding streets. It feels more like a neighbourhood common than a formal London park.
Saturday is the best time to come, when Broadway Market and the nearby food stalls turn the area into a long, busy lunch stop. On a warm day, bring a picnic and expect half of east London to have had the same idea.
