Swimming at Hampstead Heath

Open-air swimming is internationally famous on Hampstead Heath with our Bathing Ponds and the Parliament Hill Lido. The Ladies' and Men's Ponds are the UK's only lifeguarded open water swimming facilities open to the public every day of the year. The Lido is a 60 x 27 metre uncovered, unheated swimming pool at Parliament Hill.

Please note that apart from life-guarded areas of swimming ponds, swimming in Hampstead Heath ponds is very dangerous and not permitted.


Paid car parking is available at the Lido and East Heath Road car park, and pay-and-display street parking is available on Millfield Lane. These collectively provide close parking for all our swimming facilities.

Cold water swimming guidelines

An independent safety audit of our swimming facilities has identified medical issues surrounding the acclimatisation associated with year-round swimming in water cooler than 12°C degrees.

Three main problems associated with immersion in cold water have been identified:

  • numb freezing cold injury
  • hypothermia
  • sudden immersion syndrome (SIS)

It's recommended that you seek a medical check-up before swimming in cold water, with the examining doctor having been told the purpose of the examination.

For acclimatisation to occur, swimmers should continue swimming from summer through autumn into winter, preferably three or four times a week. Only brief immersion is necessary for acclimatisation, for example: two or three minutes on each occasion.

For more information, please call us on 020 7485 5757.
