The Best Water Parks in the UK for a Family Camping Trip
· Updated
The best water parks in the UK for a family camping trip fall into three types: big indoor slide complexes for rainy days, outdoor lidos for a proper sunny afternoon, and inflatable aqua parks for older, confident swimmers. Which one suits you depends on your children's ages and where you are pitched, not on which park shouts loudest about being the biggest.
Below we have grouped the strongest options by region so you can match a splash day to your trip. Book every one of them online before you travel, because the good sessions sell out in the school holidays and turning up on spec is how you end up sat in the car park. This guide sits alongside our advice on child-friendly campsites in the UK, and you can find and compare sites near any of these parks over at Camping Sites in Britain.

The Midlands: indoor slides whatever the weather
The Midlands has the densest cluster of proper indoor water parks in the country, which makes it the safest bet for a rainy camping week. All three below stay warm and open year round.
Alton Towers Waterpark, Staffordshire
Alton Towers Waterpark, part of the wider resort and attached to the Splash Landings Hotel, is the most family-complete of the lot. Its Caribbean theme covers a wave pool, a lazy river, a handful of flumes including the Master Blaster, and a shallow, warm toddler area, so it genuinely works from babes in arms up to teenagers. You can visit the waterpark on its own without a theme park ticket, which many families forget. Book a timed session in advance, as it is a separate booking from the rides.
Waterworld, Stoke-on-Trent
Waterworld is the one to pick if your children are old enough to want a scare. It leans harder into fast, dark flumes than anywhere else on this list, with a big indoor and outdoor mix, and it runs across the year rather than just summer. Younger children are catered for with a gentler splash zone, but the draw here is the thrill rides, so it suits families whose youngest is roughly seven or over. Check the height and confidence requirements for the big slides before you go.
The Wave, Coventry
The Wave is Coventry's modern indoor waterpark and a strong all-rounder for mixed-age groups. It combines flumes and a wave feature with a dedicated toddler and young-children area, and being newer it tends to feel less tired than some older pools. It is handily placed for families touring the Midlands and Warwickshire. Sessions are timed and capped, so pre-booking online is close to essential in the holidays.
The North West: Blackpool's big splash
The North West's headline water park is on the Blackpool seafront, which makes it easy to pair with a classic bucket-and-spade break.
Sandcastle Waterpark, Blackpool
Sandcastle Waterpark is one of the largest indoor water parks in the country and a reliable all-ages day out. It runs a big spread of slides and flumes alongside a warm, shallow area for little ones, so it copes well with families where the children are years apart in age. The taller flumes carry minimum height and adult-supervision rules, which the staff enforce, so check your youngest clears them before you queue. It sits directly opposite the Pleasure Beach, making a two-attraction day easy to plan. If your trip is more likely to be rained on than not, keep an indoor park like this in your back pocket alongside our list of campsite games for rainy days.
The South West: proper outdoor lidos
Lidos are the outdoor, sunny-day answer to a water park, and the South West has two of Britain's best. They are heated swimming venues rather than slide parks, so they suit gentler, splashier days with younger children and anyone who prefers a swim to a scream.
Sandford Parks Lido, Cheltenham
Sandford Parks Lido, also known as Cheltenham Lido, is one of the largest heated outdoor pools in the country and a lovely spot on a warm day. Alongside the main pool it has a separate children's pool and paddling area plus grassed lawns for a picnic, which makes it far more relaxed than a busy indoor flume park. It opens seasonally, broadly across the warmer months, so check the dates and session times before building a day around it. It is an easy add-on to a Cotswolds camping trip.
Jubilee Pool, Penzance
Jubilee Pool is a striking Art Deco sea-water lido right on the harbour at Penzance, and Britain's largest of its kind. The main pool is unheated sea water, so it suits older children and hardier swimmers, though there is a separate geothermally heated section that stays warm year round for a gentler dip. It is as much a place to visit as to swim, and it pairs naturally with a Cornish camping trip. Browse campsites in Cornwall if you want to base yourself near the far west.
The South: inflatable aqua parks for confident swimmers
Inflatable aqua parks are the giant floating obstacle courses you climb, slide and bounce across on an open-water lake. They are brilliant fun but they are not for everyone: you must be a confident swimmer, buoyancy aids and wetsuits are compulsory, and there is a minimum age, usually around six to eight. They are seasonal, weather-dependent and booked in timed slots.
New Forest Water Park, Hampshire
New Forest Water Park, near Fordingbridge on the Hampshire and Dorset border, runs a well-established inflatable aqua park on its lake alongside wakeboarding and paddleboarding. It is a solid choice for families with older children who can swim, and staff brief every session and fit everyone with a buoyancy aid. Sessions run through the warmer months only, so book a slot in advance and check the minimum age for your youngest. Bring towels and warm layers for afterwards, because lake water is cold whatever the air temperature.
Liquid Leisure, Berkshire
Liquid Leisure near Windsor has long been one of the best-known aqua parks in the South East, with a large inflatable course and wake facilities. Its future has been reported as uncertain, so this is one to confirm is open and running your dates before you plan around it. As with any aqua park, it is for confident swimmers only, with wetsuits and buoyancy aids required. If it is closed when you look, New Forest Water Park is the nearest comparable option.
How to choose the right water park for your family
Match the park to your youngest and least confident swimmer, not your oldest thrill-seeker. Indoor parks with a warm toddler zone (Alton Towers, Sandcastle, The Wave) are the most forgiving for a spread of ages, thrill-led parks (Waterworld) suit families whose youngest is seven or over, and lidos and aqua parks reward warm weather and swimming ability.
A few practical points apply almost everywhere. Sessions are timed and capped, so pre-book online rather than risking the door. Under-eights nearly always need an adult in the water with them at a one-to-one or one-to-two ratio, so check the supervision rule before you buy. Bring your own towels, and budget for lockers and a hot drink. If you are travelling with very little ones, our guide to camping with a baby covers the kit that makes days like these easier, and enjoying the great outdoors with kids has more on keeping a mixed-age group happy.
Frequently asked questions
What is the biggest indoor water park in the UK?
Sandcastle Waterpark in Blackpool is one of the largest indoor water parks in the country, with a big spread of slides plus a warm shallow area for young children. Waterworld in Stoke-on-Trent is another of the largest and leans more towards thrill rides.
Are UK water parks suitable for toddlers?
Yes, the indoor parks with dedicated toddler zones are. Alton Towers Waterpark, Sandcastle and The Wave all have warm, shallow areas built for little ones. Inflatable aqua parks and unheated lidos are not suitable for toddlers.
Do you need to book water parks in advance?
Yes. Almost every park on this list runs timed, capped sessions and can sell out in school holidays. Book online before you travel rather than turning up on the day, especially in July and August.
What is the difference between a lido and an aqua park?
A lido is an outdoor swimming pool, often heated, for swimming and paddling. An inflatable aqua park is a floating obstacle course on open water that you climb and slide across, and it requires a wetsuit, a buoyancy aid and confident swimming.
How old do children need to be for an inflatable aqua park?
Usually around six to eight, and they must be able to swim confidently. Each park sets its own minimum age and requires buoyancy aids, so check the rules for New Forest Water Park or your chosen venue before booking.
The short version
For a rainy camping week, book an indoor park in the Midlands or Blackpool. For a hot day, head to a South West lido, and for older confident swimmers, an inflatable aqua park is hard to beat. Whichever you pick, book ahead, then find a base nearby among our child-friendly campsites in the UK or browse the full campsite directory.
