Best Outdoor Pools In London 2025
Hampstead Heath Swimming Ponds
Probably one of the most picturesque outdoor swimming spots in London, if not the UK. Set amongst 800 acres of Hampstead Heath parkland, there are three ponds – women’s, men’s and mixed – open everyday from 7am (closing times vary according to the seasons). Tickets for the following week are sold in slots and released at midday every Monday; they sell out quickly, so make sure your finger’s on the buzzer!
Address: Hampstead Heath, London NW5 1QR
Parliament Hill Fields Lido
Built in 1938, this Grade II-listed Parliament Hill Lido is one of the biggest and best lidos in London at 60 metres by 28 metres. Unheated, you might want to consider a wetsuit on cooler days. And like all public outdoor pools in London you’ll have to arrive early during a heatwave. This pool’s USP is its stainless steel pool liner (the only in the UK), but if this doesn’t impress the kids, the under-five’s paddling pool and onsite café should please them.

Beckenham Place Park Swimming Lake
If you’re slumped at your desk and after some time out, why not try a bracing start to the day to blow away the corporate cobwebs and meet the sunrise en plein air. Perfect for icy outdoor swimming fanatics and those just wanting to try something a little bit different. It’s a purpose-built lake for swimming that’s open generally from 7am to 3pm, but check the website for timing specifics.
Address: Beckenham Hill Rd, London BR3 1SY
Tooting Bec Lido
At 90 metres long, Tooting Bec Lido is the largest outdoor pool in London, the second-largest outdoor freshwater pool in Europe, and the UK’s biggest. It reopened recently last year following a big revamp, and with its iconic changing huts lining the sides, it’s a picturesque spot for an energetic morning swim, or a poolside bathe. Despite its 14-hour opening hours, you’ll struggle to find a quiet time on a hot summer’s day.
Address: Tooting Bec Rd, London SW16 1RU
Serpentine Lido
The UK’s oldest open water swimming location is Serpentine Lido on Hyde Park. There’s the Lido Cafe Bar for post swim refreshments by the water – ideal for a snack, a meal, or even a glass of wine. And, of course, Hyde Park is right there for a cool-down stroll.
Address: Hyde Park, London W2 2UH
Hampton Pool
Fancy a moonlight swim? A 28°C swim? A classic swimming lido built in the early 20th century? Hampton Pool has it all. Book ahead to avoid disappointment. If you really love it, you can even purchase a branded towel or tote bag – all proceeds go to keeping the pool open year round at a low cost.
Address: High St, Hampton TW12 2ST
London Fields Lido
Soak up some of the East London cool at London Fields Lido, and grab a bite from one of the many stalls, cafes and restaurants at the nearby Broadway Market after. There’s a sundeck, space for sunbathing and a cafe, and swimming is available all day, all year round – make sure you book ahead to secure your slot.
Address: London Fields West Side, London E8 3EU
Charlton Lido
If you’re not convinced by outdoor swimming in the UK, this heated, Olympic-sized pool in Greenwich might convert you. Soak up the sun on the terrace, sipping on a drink from the Coffee Corner, before taking a dip in the water without having to brace yourself for the cold. Lush.
Address: Hornfair Park, Shooters Hill Rd, London SE18 4LX
Brockwell Lido
Not only is this lush 50-metre pool surrounded by easy-on-the-eye Grade II-listed art deco buildings, giving you something nice to look at while you swim, said buildings house the excellent Lido Café, so you can grab a well-earned pizza after your lengths. It’s a real community affair, with a Brockwell Lido Users’ Group ensuring the buildings and site are used for a range of activities locals can enjoy. Oh, and over 60s swim free weekdays before 10am.
Address: Brockwell Park, Dulwich Rd, London SE24 0PA
Finchley Lido Leisure Centre
Officially open everyday until further notice (it’s usually temperature dependent…), Finchley Lido in Barnet is a petite pool with a grassy terrace to dry off on after a dip. Located in a leisure park, you could even go for a game of bowling afterwards if you fancied it. Make sure you book ahead!
Address: Great North Leisure Park, High Rd, London N12 0GL
