London may not have a coastline, but it does have swimming ponds, reservoirs, floating pools, lakes and lidos hidden between parks, skyscrapers and woodland. Some are ideal for a relaxed sunny-day dip, while others are better suited to longer open-water swims.
Before you grab your towel, here are the London and near-London swimming spots worth knowing about this summer, from Hampstead Heath’s legendary ponds to riverside swims worth leaving the city for.
Hampstead Heath ponds
Best for: London’s most iconic wild swimming experience.
Vibe: Leafy, cold, cult-status.
Hampstead Heath’s three natural swimming ponds and one lido are hardly a secret anymore, but that doesn’t make them any less special.
The Kenwood Ladies’ Pond, Highgate Men’s Pond and Hampstead Mixed Pond each have a different way to experience the Heath from the water.
The Ladies’ Pond and Men’s Pond are open year-round, while the Mixed Pond is seasonal, usually open from April to October. During summer, some sessions are bookable and sell out quickly, so this is one to plan ahead rather than leave to a spontaneous heatwave decision.
Why it makes the list: This is the classic London swim: cold water, trees overhead and the slightly surreal feeling that you’re taking a dip in the middle of the city.
Good to know: Book ahead in summer, especially for peak sessions. If you’re new to cold water, start slow and check the latest opening times before you go.
Sea Lanes Canary Wharf
Best for: A “wait, this is in London?” swim.
Vibe: Floating pool, dockside sauna, post-work swims.
Sea Lanes is a Canary Wharf oasis for open-water swimming. Open year-round in Eden Dock, this 50-metre six-lane natural outdoor floating pool is fully lifeguarded and designed to make open-water swimming more accessible.
For non-members, public bookings open one week before each session, while members can book up to two weeks ahead. Pay-per-swim tickets are available, with swim and sauna options also offered.
Why it makes the list: It has the rare combination of proper open-water atmosphere and city convenience. You can swim surrounded by Canary Wharf’s towering buildings, then head straight for a sauna or food by the water.
Good to know: This is one to book in advance, especially in warm weather, as walk-in availability is not guaranteed during busy periods.
West Reservoir, Hackney
Best for: Open-water training without leaving North London.
Vibe: Calm, practical, local favourite.
West Reservoir Centre in Woodberry Down has open-water swimming in a natural reservoir in Hackney, just a short walk from Manor House station. The reservoir is fully supervised, with course options ranging from a 100-metre warm-up course to a 300-metre loop.
Bookings are strongly advised, especially at peak times, and all swimmers must use a tow float and wear a bright red, orange or pink swim hat. Sessions are for confident swimmers, but newcomers are welcome to start under the reservoir staff’s supervision.
Why it makes the list: It feels more functional than whimsical, but that’s the appeal. If you want a proper swim in open water rather than just a quick dip, West Reservoir is a solid choice.
Good to know: Changing facilities are limited while improvements are ongoing, so arrive swim-ready where possible.
Beckenham Place Park Swimming Lake
Best for: A South London lake swim.
Vibe: Park day, open water, picnic after.
Beckenham Place Park has London’s first purpose-built swimming lake, which is 285 metres long and reaches depths of up to 3.5 metres. The lake is open for pre-booked swimming and paddleboarding sessions.
The wider park is Lewisham’s largest green space, with 96 hectares of parkland, nature trails, cafés, playgrounds and plenty of space to make a day of it.
Why it makes the list: It’s one of the easiest spots to turn into a full day out. Swim first, then stay for the park, coffee, a walk or a picnic.
Good to know: Sessions should be booked in advance, and the lake is a managed swimming environment rather than an unsupervised wild swim.
Hyde Park Serpentine Lido
Best for: A famous central London dip.
Vibe: Iconic, summery, tourist-meets-local.
The Serpentine Lido is one of London’s most famous open-air swimming locations, set in the heart of Hyde Park. Public swimming usually runs on weekends from mid-May and daily from June to mid-September, with opening times generally listed as 10:00 to 18:00.
Why it makes the list: When open, it’s hard to beat for central London novelty. You’re swimming in Hyde Park, with the city just beyond the trees.
Good to know: Public swimming is seasonal, so check opening dates and session times before you travel.
Luxborough Lake, Chigwell
Best for: A peaceful swim on the London and Essex edge.
Vibe: Low-key, scenic, good for regular open-water swimmers.
Luxborough Lake is an open-water swimming spot in Chigwell, Essex. It’s open year-round and sessions are offered for open-water beginners, recreational swimmers and more experienced athletes.
All swimmers need to complete an induction before regular swimming.
Why it makes the list: It’s not central London, but it’s a good spot for anyone who wants a calmer open-water venue without heading all the way to the coast.
Good to know: All swimmers need to follow the venue’s booking and induction process, so don’t treat this as a turn-up-and-jump-in lake.
Pangbourne Meadow, Berkshire
Best for: A wild swimming day trip from London.
Vibe: River Thames, meadows, worth the train.
Pangbourne Meadow sits on a stretch of the River Thames in Berkshire and is often highlighted as one of the better wild swimming spots within reach of London. Better still, it’s just a short walk from Pangbourne Station, making it a realistic day trip if you want to swap the city for open river, grassy banks and a post-swim pub plan.
Why it makes the list: While it’s not technically London, it’s close enough for a swim-and-pub day trip.
Good to know: It’s river swimming, so conditions can change. Check the latest local guidance, river flow and weather before entering, and avoid swimming alone.
