The Serpentine Lido is undoubtedly one of London's most iconic 'open water' swimming locations. It is located in Hyde Park and open to the public through out the summer until mid September. It’s a rectangular patch roped off from the rest of the lake (to avoid any collisions with pedalos and/or wildfowl), and thanks to its great facilities - is one of London’s more comfortable wild swimming spots.
You’ll find changing rooms on-site, and sun loungers for hire along the lake’s banks. Alongside the Serpentine Lido is the Lido Cafe Bar which has waterside tables and is a great spot to enjoy a snack, meal or a glass of wine. The renowned brunch menu includes dishes like sweet potato cakes with smashed avo and poached eggs; lunch numbers like giant reuben sandwiches and burgers; and sundowners in the form of draught beers and pitchers of Pimms.
The Serpentine Swimming Club is the oldest swimming club in Britain. They swim every day in the Lido area between 5:30 am and 9:30 am and also during the famous race on Christmas day. Hardcore members of the Serpentine swim club famously come together on Christmas Day to swim the Peter Pan Race. An annual tradition since 1864, swimmers tackle 100 yards (through water that often freezes over entirely), to win a cup originally presented by J. M. Barrie, the author of Peter Pan.
The Lido opens at 10am and closes at 6pm, with the morning session until 1.30pm and the afternoon session kicking off at 2.30pm. Adults pay £7 for a full day session and £5.50 for a half day, whereas children up to 15 years of age can swim for £3.50 or £2.00 for a day session.
