The Best Splash Parks in London This Summer: A Family Guide to Cooling Off in the City
When London temperatures climb, families across the capital start searching for the same thing: somewhere fun, free (or affordable), and guaranteed to keep the kids cool. Enter London’s brilliant splash parks, fountains, and water play areas.
From giant dancing fountains in King’s Cross to hidden neighbourhood splash pads perfect for toddlers, London has plenty of places where children can run, splash, and burn off energy while parents enjoy a summer day outdoors.
Here’s our guide to the best splash parks in London for families this summer.
Granary Square Fountains, King’s Cross
Best for: All ages, central London adventures
If you’ve ever searched for “best splash park in London,” Granary Square almost always tops the list — and for good reason.
Located behind King’s Cross Station, this famous public square features over 1,000 choreographed water jets that shoot up from the ground in constantly changing patterns. Kids absolutely love racing through the fountains, trying to predict where the next spray will appear.
Parents love it too because there’s plenty nearby: cafés, restaurants, shaded seating, and even a quick walk to Coal Drops Yard for food or shopping.
Family tip: Bring a full change of clothes — children rarely stay “just slightly wet” here.
Nearest station: King’s Cross St Pancras
Appearing Rooms, Southbank
Best for: Unique summer experiences and unforgettable photos
Part art installation, part giant water playground, Appearing Rooms on the Southbank offers something genuinely different.
Temporary “walls” made entirely from falling water create changing rooms and pathways that visitors can walk through, dodge, or get completely drenched inside.
Kids find it magical. Adults secretly love it too.
Being on the Southbank means you’re also close to food markets, riverside walks, and family attractions.
Family tip: Waterproof sandals are your friend here.
Nearest station: Waterloo
Bishops Park Splash Park, Fulham
Best for: Younger children and full family park days
If your ideal summer outing includes playgrounds, riverside walks, and a proper splash zone, Bishops Park should be high on your list.
This much-loved West London spot combines a fantastic playground with an interactive water play area featuring sprays, fountains, and splash features designed especially for children.
The surrounding park is spacious and beautiful, with picnic spots, football pitches, gardens, and views along the Thames.
It feels less touristy than central London options and more like a hidden family favourite.
Family tip: Pack a picnic — this is an easy place to spend half a day.
Nearest station: Putney Bridge
Queen Elizabeth Olympic Park Fountains, Stratford
Best for: Big energy kids and active summer days
The Olympic Park splash fountains are ideal for children who like to run, jump, and stay moving.
The fountains sit within the huge Queen Elizabeth Olympic Park, giving families access to playgrounds, green spaces, cafés, and walking routes all in one trip.
Because the area is so large, it’s easier to spread out compared with some smaller splash pads across London.
This makes it a particularly good option for families with multiple children of different ages.
Family tip: Combine your visit with the Tumbling Bay Playground nearby for a full adventure day.
Nearest station: Stratford
Kensington Memorial Park Water Play Area
Best for: Toddlers and preschoolers
Parents of younger children often want something slightly smaller, safer, and easier to supervise. Kensington Memorial Park delivers exactly that.
The water play area here is designed with little ones in mind, offering gentle jets, splash features, and a secure environment that feels manageable even during busy summer weekends.
There’s also a well-equipped playground nearby, making it ideal for combining water play with climbing, swings, and slides.
Because it’s tucked away in West London, it often feels more relaxed than central tourist hotspots.
Family tip: Arrive earlier in the day during school holidays to avoid peak crowds.
Nearest station: Ladbroke Grove
Merchant Square Fountain Maze, Paddington
Best for: School-age children who love a challenge
This isn’t your typical splash park.
Merchant Square’s interactive fountain maze creates a playful obstacle course of water jets that appear and disappear unpredictably from the ground.
Older children especially enjoy the “challenge” element — running through without getting soaked (spoiler: they almost always fail).
Its central location makes it perfect for adding onto a London sightseeing day or canal-side walk.
Family tip: Grab lunch nearby and watch the boats along the Paddington Basin canals.
Nearest station: Paddington
What to Pack for a London Splash Park Day

Swimwear or quick-dry clothes
Towels
Spare outfit for every child
Waterproof shoes or sandals
Sun cream and hats
Refillable water bottles
Snacks or picnic supplies
Wet bag for soggy clothes
Trust us — you’ll thank yourself later.
