Spending time outdoors is increasingly recognized as a powerful way to support mental well-being. Many people are turning to nature-based activities to help manage stress, anxiety, and depression. While demand for mental health services in London continues to grow, simple lifestyle habits—like getting outside and moving—can make a meaningful difference.
One activity gaining serious traction is open water swimming. More than seven million people across the UK are now diving into lakes, rivers, and ponds for both physical and mental benefits. And in London, outdoor swimming spots offer a rare opportunity to escape the urban rush and enjoy a refreshing reset.
If you’re traveling to London this summer, consider carving out time for an open water swim. It’s a memorable and revitalizing way to experience the city—and a great reminder of how nature can play a role in healing. While you’re planning, make sure you stay connected easily with Holafly’s esim in the UK so you can book swims, navigate the city, and share your adventures stress-free. Here are some of London’s best swimming spots to explore…
Hampstead Heath Ponds
Tucked away in one of London’s most beloved green spaces, Hampstead Heath boasts three swimming ponds: one for men, one for women, and a mixed pond. These spring-fed ponds offer a truly unique swimming experience in the heart of the city.
Surrounded by trees and wildlife, the ponds provide a peaceful, almost countryside-like atmosphere. Lifeguards are present, and the ponds are open year-round, although they are especially popular during the summer months. Be prepared, the water can be quite chilly, even on hot days, but that’s part of the charm. Early morning swims are particularly serene, offering a rare moment of calm before the city fully wakes.

West Reservoir, Stoke Newington
For a slightly more organized wild swimming experience, head to the West Reservoir in Stoke Newington. This former reservoir has been transformed into a dedicated open water swimming facility, offering clean, calm waters with stunning views of the surrounding architecture and nature.
Swimmers must book in advance and wear a brightly colored swim cap for safety. The West Reservoir caters to more serious swimmers, offering a variety of swimming distances, but it’s also accessible for confident beginners looking to try open water swimming in a controlled environment.
Beckenham Place Park Lake
Opened in 2019, Beckenham Place Park Lake is one of London’s newest open water swimming locations. Set within a beautifully restored Georgian park in Lewisham, the lake offers a tranquil spot to cool off during the summer heat.
The lake features a designated swimming area with lifeguards on duty, and wetsuits are available to hire if you’re not keen on the cooler temperatures. Surrounded by lush parkland, it’s a fantastic place to spend a summer afternoon, with café facilities and picnic spots nearby.
River Thames at Petersham or Shepperton
While much of the Thames isn’t suitable for swimming, certain stretches in west London are popular with experienced wild swimmers. Petersham Meadows, near Richmond, offers a picturesque setting for a river swim, with gentle currents and beautiful scenery.
Further out, Shepperton offers a quieter stretch of the Thames that’s popular with wild swimming enthusiasts. However, always check water quality reports before swimming in the Thames and be aware of tides, currents, and boat traffic. This option is best suited to strong swimmers familiar with open water safety.
The Serpentine, Hyde Park
The Serpentine is perhaps London’s most famous and possibly best, open water swimming spot. Located in Hyde Park, this large lake has been a favorite of Londoners since the Victorian era. The Serpentine Swimming Club operates year-round, but from June to September, anyone can swim in the Lido section.
The water here is regularly tested for safety, and the Lido includes sunbathing areas, changing facilities, and a café for post-swim refreshments. It’s an excellent option for those wanting a taste of wild swimming without leaving the comfort of central London.

Divers Cove, Godstone (just outside London)
Though technically outside London, Divers Cove in Godstone, Surrey, is easily accessible. It is well worth the trip for outdoor swimmers. This former sand quarry has been converted into a stunning open water swimming venue. It has clear turquoise water and a peaceful atmosphere.
Swimmers must pre-book their sessions, and wetsuits are recommended due to the cooler water temperatures. With lifeguards on duty and a friendly, welcoming vibe, Divers Cove is perfect for a summer day trip out of the city.
