Not your average primary-coloured slide and swing set: free, often staffed, child-led spaces where kids climb, build, dig and take proper risks.
These are one of London's best-kept secrets for kids. There might be climbing, building, digging and risks — they're usually aimed at drop-offs for older children aged 6+, but some run family sessions for younger ones too.
They're also often at the mercy of council funding, weather and seasons, so check each site's opening times before you set off.

23 playgrounds across 9 boroughs
Opened in 2005 in the shadow of Tottenham Hotspur's stadium, this purpose-built site has a treehouse, pond and stream, water-ring swing and a huge slide. Run by the Haringey Play Association, with regular family sessions in the holidays.
Set inside a converted Victorian pump house in Markfield Park, with most of the play structure and the building itself wheelchair accessible. Zip wire, roundabout, mud kitchen and sensory play areas — calm and well maintained.
A nature-focused playground with tunnel slides, insect houses, water play and multi-level climbing structures built into the tree line. Run by the small Lloyd Park Children's Charity.
A community-run charity playground with play workers on site, a big sandpit, zip line, skate ramp and a large indoor soft-play space. Lots of events on the calendar.
A sprawling council-run site with go-karts, climbing rocks, a water pump and a large sandpit ringed with playhouses. Winner of London's Most Innovative Adventure Playground — mainly for Hackney residents or children at Hackney schools.
Famous locally for its huge climbing net tower, two tunnel slides and quirky touches including a Star Wars mural. There's also a wilder, muddier area with treehouses for den-building.
One of the original 1955 bomb-site adventure playgrounds built in England, and still going. It leans into its scrappy roots with loose parts, pallets, crates and homemade-looking structures built up over the years by the children themselves.
Islington runs 11 free adventure playgrounds, all staffed by trained playworkers, open term-time afternoons and school-holiday days. They're generally designed for children aged 6 to 13 who live or go to school in the borough. Here are some of the best.
Best known for its red double-decker bus play structure, plus a pirate ship and a giant stone head to climb.
Built from the rubble of demolished tenements in the 1970s, it now has rope-bridge treehouses and a generous sandpit.
Good for confident climbers, with tall structures, a rope ladder and a zip line.
Islington's most central site, with a large netted climbing fortress and a castle-maze structure.
Grassy and relaxed, with a treehouse, a small stage and a well-stocked craft room.
A green, slightly wilder site with a frog pond and a tunnel slide feeding into a zip line and crash mats.
Running since 1974 and recently given a 50th-anniversary revamp, this community centre and playground tucked into Weavers Fields has toddler equipment, a zip line, open grassy banks and loads of events.
On a quiet cul-de-sac, this one stays fairly under the radar, with a big sandpit, go-karts and a wheelchair-accessible seesaw.
Greenwich runs a few sites, all supervised by trained staff and focused on ages 6–16, although some are a bit run down. Options include Coldharbour, Glyndon and Plumstead Adventure Play Centre.
Youth centre, playground and community hub in one, with a packed calendar for local families.
A green, wooded site on Metropolitan Open Land with treehouses built around the existing trees, a zip wire and an outdoor gym.
Run by Oasis Children's Venture, with a zip line, sports area, tyre and rope swings and a forest garden. It gets busy and can reach capacity by late morning on Saturdays and in the holidays.
Built on a WWII bomb site in North Lambeth and run today by the Kennington Association, with plenty of scope for children to build their own play spaces rather than use fixed structures.
London's oldest adventure playground still on its original 1957 site, run independently of the council since it opened. Zip line, aerial walkway, fire pit and an allotment where children cook with what they've grown.
Home to a large yellow submarine structure kids can climb inside, plus big swings, a raised walkway and plenty of open grass for football.
Closed unexpectedly for a few years in the 2010s but back up and running, with weekend adventure play sessions and extra midweek dates in the school holidays.
The net climbing tower stands out, as does the face-to-face tango swing, alongside a giant climbing frame, fire pit and treehouses.
