Are you wondering where to swim in London? Perhaps you’re a keen swimmer planning a visit to the UK’s capital (like me) or maybe you are new to swimming and keen to find all the top spots in the city you call home. Whichever, this article will help you find great places to swim in London, both indoors and outdoors.
And whilst it’s hard to find genuine wild swimming, London does have some spots that can feel wild, even close to the city centre.
Who am I? My name is Seana Smith, I’m a Scot now living in Australia and, on visits back to the UK, I love to find new places to swim. This article starts with a list of the places I have been to already, and where I suggest you start, followed by a list of all the swimming spots I plan to explore on my next visits to London.
Outdoor Swimming In London

Hampstead Heath Swimming Ponds
There are three natural swimming ponds at Hampstead Heath: The Kenwood Ladies Pond, The Highgate Men’s Pond and the Hampstead Mixed Pond. All of these ponds are completely natural, with deep water, surrounded by trees and plants.
My daughter and I met a friend at the Ladies Pond when we visited London and spent a really relaxing few hours there, swimming, lying on the meadow under a shady tree and nattering joyfully.
The Kenwood Ladies Pond and The Highgate Men’s Pond are open all year round. Hampstead Mixed Pond is open only over the summer months, from mid-April to October. There is a fee to enter each pond and at some times of the day and season, tickets need to be pre-booked. Check the website for all the details.
The opening hours vary by the season, so do check on the website for current opening hours, click here.
On warm days in summer, these pools are very busy and you are best to book ahead, or face very long queues. In winter, the temperature of the water in the ponds is very low, this makes for very serious cold water swimming, so do be careful. Lifeguards are on duty.
Address: All three ponds are easily accessed from Millfield Lane, Hampstead Heath.



Parliament Hill Lido
This 60 metre long pool is open every day of the year and is not heated. It can be very busy – and full – in summer. Hardy winter swimmers enjoy it for its cold temperatures, and can then warm up in the on-site sauna.
I loved this pool for its unusual length and for its sparkling beauty. The pool is lined with dimpled stainless steel which gleams on a sunny day. Just gorgeous!
The cafe at the pool served up a warming bowl of de luxe porridge and a very good coffee. Just what I needed after a chilly April swim.
Parliament Hill Lido was opened in 1938, the most recent renovations added the stainless steel pool liner which is such a feature of this pool.
Address: Parliament Hill Lido, Gordon House Road, London, NW5 1LT




Serpentine Lido
The marked off swimming area in the Serpentine in Hyde Park is open to the public in spring and summer, from mid-May at weekends and then daily between June and mid-September from 10am to 6pm. You can book and pay online via the website. That is highly recommended for warm days. There are sessions from 10am – 1.30pm and from 2.30pm to 6pm. Lifeguards are on duty.
There is a members-only swimming club which can use the swimming area between 5.30am and 9.30am every day of the year, but it’s strictly members only. I found this out when I arrived at 7am one morning with my cossies and a towel. I nearly cried! Should have taken my own advice and checked all the details before setting off.
Address: Hyde Park, London W2 2UH

Tooting Bec Lido
Famous for being the largest freshwater outdoor pool in the UK, Tooting Bec Lido is an exhausting 91 metres long. This pool and the kids’ paddling pool are not heated and can be very chilly. There is a cafe but you can also bring in your own picnic.
The pool is open to the public over the spring and summer, but is only open to members in the winter.
Booking ahead is recommended.
