There's little in life more tempting than a cool dip in an open-air swimming pool on a sticky summer's day. Looking to combine that with getting away from the heat of London? Read on for outdoor pools and lidos which you can visit on a day trip. (If you can't be bothered to travel far, we've covered lidos in the capital here.)
This guide covers manmade pools and lidos — some are purpose built lidos, others are local leisure centres with an outdoor pool. If you're feeling more adventurous, check out our guide to wild swimming in lakes and rivers near London. And if you want be near the water rather than in it, we've picked some of our favourite lakeside walks near London too.
Outdoor swimming pools and lidos in Kent
Faversham Pools (April-October)
Located in the centre of Faversham (a very pretty town, well worth exploring), this leisure centre has year-round indoor swimming, with the popular addition of three heated outdoor pools in the summer months. Keep an eye on the website for details of evening sunset swims during this time.
Serious swimmers can stretch their limbs in the 30m outdoor pool, which also has 1m and 3m high springboards, and a 5m diving board — a rare facility in public pools these days. Toddlers are kept entertained in their own smaller pool, complete with slides, and there's an outdoor rapids pool with splash zone for bigger kids. Both the main indoor and outdoor pools have their own hoist to help disabled swimmers into the water, and the Tides Cafe offers snacks, drinks and light meals for post-swim refuelling.

The Strand Pool, Gillingham (May-September)

Located on the banks of the River Medway, the 125-year-old Strand Pool uses filtered salt water from the river, making it the only surviving river water salt pool in the country. It all feels very modern though — there's a paddling area and elephant slide for smaller children, and a lazy river surrounds the main pool, with footbridges criss-crossing it.
Plenty of sunbathing space around the edge too — something of a cool paradise, completely hidden from passersby thanks to the high walls. Note that the separate toddler pool in nearby Strand Park won't open for summer 2025.

Outdoor pool at Tonbridge Swimming Pool (April-October)
Overlooked by Tonbridge Castle on one side, and flanked by the sprawling green of Tonbridge Park on the other, with a miniature railway chugging around out the front, Tonbridge Swimming Pool is ideally placed for a day out in the town. It's the town leisure centre, with a 25m fitness pool, plus kids' pool and toddler pool open indoors all year.
Between April and October*, the heated outdoor pool opens. At its widest point, it's 20m in length, though lane swimming isn't an option on busy days. One end has a slope into the water, ideal for toddlers, with splash buckets overhead. The indoor pool has a hoist to help disabled swimmers into the water, but unfortunately the outdoor one doesn't, and the swim-through channel between the pools has remained closed since 2020, rendering the outdoor pool inaccessible for anyone who needs the hoist.
There's usually a couple of picnic tables for spectators, but there's not loads of space, so your best bet is to swim first, then take a picnic over to the park next door. You'll need to book online in advance for busy periods — and as the only outdoor pool in the area, it gets VERY busy during any summer holiday heatwave.
*As of 2025, there are exciting plans to keep the pool open through the winter months, though details are still TBC at time of writing.

Of course, there's always the biggest outdoor pool of all — the sea. Take a look at our pick of seaside towns in Kent, ideal for a day trip from London.

Pells Pool, Lewes (summer season May-September, autumn season September onwards)
Just when we thought the Sussex town of Lewes couldn't get any lovelier, we remember it's got its own outdoor pool — ideal for cooling those muscles after clambering up the town's steep hills.
First things first, Pells Pool is unheated, so can be quite a shock to the system. It's the oldest documented freshwater outdoor public pool in the country, and the water comes from an underground spring, the only warmth coming from the sun, so it's chillier than other venues on this list. Visit later in the season, when the sun's been working its magic for a few weeks, for a warmer experience.
Temperature aside, Pells Pool is ideal for a family day out, with a 46m pool and children's paddling pool, a large lawn area for sunbathing, and a small cafe selling snacks, drinks and ice cream. There's usually a section roped off for serious swimmers to do their lengths, while leisure bathers have plenty of pool too.

Saltdean Lido, near Brighton (summer season May-September, winter season from October)
If you visit one place on this list, make it Saltdean Lido. Even non-swimmers and complete aquaphobes should visit at least once in their lives, simply to gawp at the seductive, iconic curvilinear building, which led to the Lido being labelled as "probably the most architecturally significant open-air pool in the country” by the 20th Century Society. It's had a tumultuous history and almost been demolished a couple of times, but after a restoration project, the 40m pool was reopened in 2017. It has a small museum-style heritage hub on site where you can learn more about its history, and you can even get married at the lido.
Lane swimming or family swim sessions are offered in the 40m pool, surrounded by sunbathing lawns. Don't forget your sunscreen — the light really reflects off the pool and the whitewashed surroundings. Special events through the summer include moonlight swims, and Dogtember, when dogs are allowed in the pool at the end of the summer season.

Sea Lanes, Brighton (year-round)
View this post on Instagram
A relative newcomer on the outdoor swimming scene, Sea Lanes Brighton is a 50m heated open air pool on the seafront in Brighton, and is the UK’s first national open water swimming centre. Focus here is on the serious, sporty side of swimming, so it's not somewhere for a family day out, but if you're itching to get some lengths in while enjoying the sea air, it might be the place for you. Note that all swimmers must wear a swimming hat in the water.

Outdoor swimming pools and lidos in West Sussex
Arundel Lido, Arundel (heated April-September, cold water swimming the rest of the year)
View this post on Instagram
The only remaining lido in West Sussex, Arundel Lido offers stunning views of the turrets and towers of nearby Arundel Castle as you swim (best viewed when there are fewer leaves on the trees, if you can bear to swim in the chillier months). The two pools and sunbathing area are hemmed in by the River Arun on two sides, a car park on one side and housing on the other, meaning it's somewhat overlooked by the nearby houses. However, its central Arundel location means it has community spirit in buckets, hosting events such as teddy bear picnics throughout the year, swimming lessons, aerobics and fitness classes — as well as regular coffee mornings. Oh, and did we mention the castle views?

The Triangle, Burgess Hill (summer months only)
Leisure centre The Triangle is exactly what our childhood dreams were made of — flumes and rapids and jacuzzis and a beach area. And that's just the indoor, year-round pool.
In summer months, the curved outdoor pool opens too, with steps at one end for easy access, and surrounded by a Mediterranean-style patio.

Findon Swimming Pool, Worthing (May-September)
Something only really known to locals, Findon Village Swimming Pool is located behind St John the Baptist Primary School in the village — but it's open to everyone. Usually the season runs May-September for certain public sessions. If you've got a big enough group of family and friends (including a couple of qualified first aiders), why not club together for a few hours of pool fun via private hire?
Findon Village Swimming Pool, Worthing, BN14 0TR.
Don't be fooled by talk of Worthing Lido — though it was once a beautiful, seaside swimming pool in the West Sussex town, the pool was built over in the late 1980s. These days, The Worthing Lido is simply an amusement centre, with your only swimming option being the sea, a few metres away.
Sussex too has plenty of coastline if sea swimming is your thing — here's our guide to seaside towns to visit in Sussex.

Guildford Lido (April-September)
Guildford Lido is a seriously impressive pool, 50m in length and drawing visitors from miles around. With four acres of landscaped gardens surrounding the water, it's somewhere you could bring a picnic and spend the day.
Up to 10 lanes are in place at once for serious swimmers, but the real fun of this place is the slides — four blue flumes twirling you around and throwing you out at a separate landing pool alongside the main pool. Definitely one of our top picks if you've got kids in tow, though note it gets VERY busy on warm weather weekends, so get there early to plonk your towel/picnic blanket down on the grass, and be prepared for long queues at the food/ice cream kiosk. Oh, and that tower you can see from the pool? It's nearby St John's Stoke Church.
Guildford Lido, Stoke Road, Guildford, GU1 1HB. April is classed as 'winter season' with fewer sessions, before 'summer season' begins in May, running to September.
Note that the nearby Stoke Park paddling pool remains closed for the time being.

Thames Lido, Reading (year round)
View this post on Instagram
If you're looking to do laps with a side of luxury, Thames Lido is the one, describing itself as an 'urban retreat' rather than a bog-standard pool. Thankfully its name doesn't come from the (heated) water within it, but rather its location on the banks of the river.
It's been open in its current, upmarket form since 2017, though there's been a pool here since 1902. It's certainly not your local leisure centre — unless you're a member, it'll cost you £25 for a two-hour session, which includes access to the pool, sauna and hot tub. Swim, Massage & Eat packages are available if you want to make a day of it. The food here isn't your usual pool caff grub — choose from the poolside tapas bar or formal restaurant, and tuck into Spanish and Mediterranean-style dishes.
At this point, the pool itself feels like an afterthought, but here's what you need to know: 25m long, heated year-round, and children are only allowed in for certain sessions. It's surrounded on all sides by the (stunning) buildings, including a restaurant terrace just a splash away from the pool, so if you don't like the goldfish bowl feeling of being watched as you swim, it might not be for you.

Northcroft Leisure Centre, Newbury, AKA Newbury Lido
View this post on Instagram
Newbury Lido has been refurbished in the last couple of years. The bad news: that seriously lengthy 72m long pool has been reduced to a trifling 50m. The good news? The extra space has been used for a splash pad, slides and a decking area, as well as a couple of beach huts.
This means there's plenty of room for everyone, whether you're getting your lengths in, splashing about, or spreading out your towel and making a day of it.

Wycombe Rye Lido

Dating back to the 1950s, Wycombe Rye Lido consists of two pools, with American-style bleachers running alongside the length of them for spectators to watch the action. A wall of trees flanks the other side, part of The Rye park in which the lido sits. The pools are heated, though if you do need to warm up, a recent refurbishment added a gym, and football and tennis courts to the complex. There's also a cafe on-site for that all-important post-swim snack.
Wycombe Rye Lido, Buckinghamshire, HP11 1Qx.
Chesham Lido (Year round)
There are records of people swimming in the waters around this spot as far back as 1898, though the first pool wasn't constructed until 1912. A couple of facelifts later, the water's looking more tempting than ever, with bunting strung in zig zag patterns, creating a festival feeling. Being open year-round means plenty of fairy-light swims in winter. The timetable is split between lane swimming and family sessions — if you've got kids, keep an eye on the schedule for inflatable sessions. Best of all, it's reachable on the Tube — Chesham station (Metropolitan line) is less than 20 minutes walk away.

The Priory Lido, Ware
View this post on Instagram
As the name suggests, Ware Priory Lido sits in the grounds of the priory in the small but pretty town of Ware. The main pool is 30m in length, and there's a smaller teaching pool too (though that's only open during the summer holidays), surrounded by grass and paved areas for sunbathing, as well as a cafe serving drinks, snacks and ice creams. As for the priory itself, it's now a wedding and events venue, so no chance of the monks stumbling across you while you fine tune your front crawl.

Letchworth Lido (May-September)
View this post on Instagram
Located on the edge of Norton Common, Letchworth Outdoor Pool is a 50m heated facility (with separate toddler pool) surrounded by trees and greenery, as befits a Garden City. It's a versatile place: in winter, the lido transforms into an ice rink.

Outdoor pool at Hitchin Swimming Centre (May-September)
View this post on Instagram
Hitchin Swimming Centre has indoor pools, and a gym and sauna on-site, as well as the heated outdoor pool. It's an impressive 50m long, surrounded by a sunbathing terrace (with palm-style trees for that holiday feel), and flanked on one side by a gorgeous redbrick pavilion building.

Hemel Hempstead Leisure Centre
In addition to its indoor pool, Hemel Hempstead Leisure Centre has a 25m outdoor pool, with a smaller outdoor pool for kids alongside it. Family swimming and lane swimming sessions are available to book

Outdoor swimming pools and lidos in Essex
Brightlingsea Lido (June-September)
The only remaining lido open to the public in Essex, Brightlingsea Lido sits right on the seafront, just a few miles south-east of Colchester, and next to the boating lake (make sure you plunge into the right body of water). It's a classic 1930s style lido with a 50m heated pool, plus a smaller pool for toddlers. The water is unheated, and even on an August morning, we were only able to stay in for 20 minutes or so before the chill got the better of us.
Changing rooms, a cafe, and space to relax surrounds the water, though be warned that there is a hire charge for chairs and loungers.
Brightlingsea Lido, Promenade Way, Brightlingsea, Essex, CO7 0HH.
Essex has plenty of lovely beaches and seaside towns and islands with the option of a dip in the sea to cool you down.
