London’s best outdoor pools and lidos

Hampstead Heath Swimming Ponds

Hampstead Heath’s swimming ponds were originally dammed-off clay pits. Three pools are open, to ladies, men and mixed groups (including accompanied children aged 8+ at the lifeguards’ discretion). The Men’s and Ladies’ Ponds are open all year round but to use the Mixed Pond in the winter season you must join the Hampstead Heath Winter Swimming Club. Even in the summer, the water is chilly. You have been warned.

Oasis Sports Centre

A 27.5m expanse of blue, the outdoor pool at the Oasis in Camden is a revelation to the uninitiated. Once you’ve discovered the open-air heated pool, sun terrace and adjacent indoor pool you’ll be hooked, just like everyone else who’s in on the secret. The Oasis is so popular at hot summer weekends and at peak times that getting any serious swimming done is difficult – best go with the modest aim of splashing about to cool down.

Tooting Bec Lido

Tooting’s vast pool, with its iconic, coloured changing huts, has been treasured by fortunate locals since it opened as a bathing lake in 1906. At just over 90m, it’s the largest outdoor freshwater pool in the country, and inspires devoted swimming all through the year. To swim in winter you must be a member of the well established South London Swimming Club, which has been based at the lido almost as long as it has existed. Facilities include a paddling pool for kids, a café, and lockers for small valuables.

London Fields Lido

A dogged 18-year campaign by the London Fields User Group saved this 50-metre lido from demolition, and it reopened in 2006. After a nine-month refurb in 2017, it's looking super swanky once again. Open year-round, it’s heated and well used: during busy holiday periods it closes at lunchtime between sessions to make sure as many people as possible can enjoy it. Picnicking is off-limits but there are two cafés.

Serpentine Lido

Early mornings and the winter months are the preserve of the Serpentine Swimming Club, but from May to September there’s a warm welcome for everyone in this section of the Serpentine lake – although the water is not heated or chlorinated, and you may find yourself sharing a dip with the local ducks and swans. There’s a gated family area with paddling pool and playarea, plus sun loungers for hire if you want to make a day of it.

Charlton Lido

After an extensive, £2 million refurbishment, this 50-metre, Olympic-sized pool in the heart of Greenwich reopened to the public in early 2013. The facility is fully heated and has two sun terraces, with a café, gym and fitness studio also on the site.

Brockwell Lido

Brockwell’s 50-metre pool is surrounded by art deco Grade II-listed buildings which house the Lido Café and exercise studios, offering year-round dance and pilates classes and activities for pre-school children.

Finchley Lido Leisure Centre

Finchley's lido is housed in a complex which includes an indoor pool, cinema and bowling alley. The lido is petite (and unheated) with a grassy terrace for lazy days in the sun. Opening is weather dependent – you won't get an al fresco swim if it’s less than 20C outside. Indoors, swimmers can plough up and down the main pool or enjoy the leisure pool’s wave machine.

Hillingdon Outdoor Pool

Formerly known as Uxbridge Lido, the Grade II-listed, 50m, open-air swimming pool has been recently restored to its 1930s glory, complete with cascades (fountains) at either end and a new, heated shallow splash pool for children. The outdoor pool is now part of a new leisure centre that includes an indoor pool of the same size. Out in the open, there’s space to chill by the pool and café for post-swimming snacks.

Parliament Hill Lido

Built in 1938, the Grade II-listed Parliament Hill Lido measures a generous 60 by 28 metres. It has a stainless steel pool liner (the only one in an outdoor pool in the UK) which gives the water a metallic shimmer – not that you'll be able to tell when it's packed full of people on a sunny day. The lido is unheated and there's also paddling pool for under-fives and a cafe on site.

Hampton Pool

This south-facing, 36-metre open-air pool, with grassy areas for sunbathing, is open and heated to a balmy 28C all year round. Built in 1922, it was saved from closure in the 1980s by a group of local residents, who continue to take part in fundraising activities. The group has rebranded itself as the Poolside Swim & BBQ Club and holds swimming and social sessions outside of normal pool hours – anyone is welcome to join.

Is there any other pool/lido option in West London?

Thank you.

Good to be reminded that chlorine-free swimming is possible in the Serpentine, also Hampstead ponds, I assume.  Are there any chlorine-free lidos?

The pebble beach at Brighton has a very steep drop from paddling to out of your depth- not suitable for unskilled swimmers of any age.   Which seaside resorts have swimming pools filled by the tide?


nearest salt water outdoor swimming for London residents is Brighton, about an hour from Victoria by train and a 10 minute walk from Brighton station to the beach. The beach is almost all pebbles but at low tide there is a small stretch of sand. This year, 2013, the sea temperature is fairly good in August and September. On windy days the sea can be quite rough and then small children should NOT go in the sea. Never dive into the sea from the pier or breakwaters.Every year young men do this and end up with serious injuries when they collide with underwater obstructions. Along the Sussex coast there are sandy beaches at Camber Sands and at West Wittering.
