Originally dammed-off clay pits, the ponds are run by the City of London Corporation. It is consulting with local residents about essential works to protect against flooding, which – though unlikely – could be catastrophic if a large quantity of rain fell over an extended period. In the meantime, the three pools remain open to ladies, men and mixed groups (including accompanied children aged eight-15, at the lifeguards’ discretion) respectively. The Men’s and Ladies’ Ponds are open all year round but to use the Mixed Pond in the winter season you must join the Hampstead Heath Winter Swimming Club. Even in the summer the water is chilly.
