London kids have 6 weeks of summer holidays and a city full of free outdoor adventures waiting right outside the door, from open parks and play fountains to festival performances and wildlife encounters.
Play in the Park with the Royal Parks
The Play in the Park project offers a free play programme of fun, creative activities and events inspired by the Royal Parks’ wildlife and open spaces. As a born-and-bred Londoner, I find it remarkable how many families still do not know this exists. The programme focuses on Kensington Gardens, The Regent’s Park, and Greenwich Park.
Being in nature from a young age, exploring, playing, and connecting with wildlife and the outdoors can have huge benefits for children and their families. Sessions encourage creative play inspired by real park landscapes. Additionally, Nature Roadshows run at seven Royal Parks on selected dates, with scavenger trails, crafts, and free activities from 11am to 3pm.
So, check the Royal Parks website before you set off. Sessions fill quickly, but most are drop-in. This is truly one of the best free activities for London kids all summer long.
Free outdoor cinema in the heart of the city
Summer in Leicester Square brings free outdoor cinema to the heart of London. Families can catch a daily programme of animated classics, sing-along musicals, and feel-good films. Screenings run every day from midday on weekdays and from 10am on weekends.
Furthermore, families can swap indoors for outdoors with open-air cinema by the banks of Regent’s Canal near Granary Square, King’s Cross. The Everyman Cinema festival is free to watch, though unticketed, so arriving early is important.
Both locations sit close to green spaces, so families can arrive early, claim a spot on the grass, and turn the whole outing into a proper outdoor day. Bring a blanket and snacks, and London kids will remember it all summer.
Explore Greenwich Park and the Docklands festival
The Greenwich + Docklands International Festival is a free programme of open-air performances spanning theatre, dance, circus, and installations. There are pop-up performances, family trails, installations, stalls, workshops, and more.
Also, Greenwich Park itself offers so much beyond the festival. The park features expansive green spaces, a deer park, shady groves, interactive trails around the Royal Observatory, and a dedicated children’s playground, with stunning views across London including vistas over Canary Wharf.
Together, the park and the festival make this one of south-east London’s most exciting summer destinations. Families can easily spend a full day here at no cost. This is exactly the kind of diverse, culture-rich experience that makes London so special for families.
Expert perspective on free summer play for London kids
London’s parks and open spaces are genuinely underused resources during summer. Families often look for structured activities, but some of the most valuable experiences for children come from unstructured time outdoors in green spaces, encountering wildlife, exploring terrain, and connecting with other children from different communities. The Royal Parks in particular offer an extraordinary variety of environments within the city, from woodland edges to open meadows and formal gardens. Free programme events add a layer of discovery that turns a simple park visit into a full learning experience. Families who build a habit of regular outdoor visits during the summer holidays consistently report lower stress and higher wellbeing for both children and adults. The city’s diversity of green spaces means every London neighbourhood has something within reach.

Spot wildlife at Hampstead Heath and city farms
Hampstead Heath offers vast open spaces ideal for kite flying, nature walks, and even wild swimming in the bathing ponds, which are lifeguarded in summer. The heath stretches from Hampstead to Highgate and is home to the highest point in London: Parliament Hill. The view here is protected, and visitors can see St Paul’s and the Palace of Westminster from the top.
In addition, city farms offer a completely different kind of nature encounter. Vauxhall City Farm offers alpacas, rabbits that visitors can brush, pygmy goats, and even Kune Kune pigs wearing sunscreen in summer. This is London’s oldest city farm and it remains free to visit, though a donation of around £4 is appreciated.
Both experiences show London kids a side of the city that feels a world away from busy streets. Nature is never far in this city, and that is something to celebrate.
Play fountains and outdoor splash zones
On hot summer days, families can cool off in one of the city’s play fountains, which are lots of fun and free. Union Park at Wembley has free paddling fountains that are perfect for younger children on warm days, with gentle jets, shallow pools, and nearby seating for parents.
Moreover, Summer Splash returns to Royal Victoria Dock as a free event, offering the great tradition of the London lido with a family-friendly atmosphere, lifeguards, shallow sections, mini-beaches, and deckchairs for parents.
Families should remember to pack a towel and spare clothes. For London kids, a play fountain on a warm afternoon is one of those simple, joyful summer memories that lasts for years. Always check opening dates before travelling.
Make the most of free outdoor London this summer
London kids are lucky to grow up in a city that offers so much for free. From the wildlife of Hampstead Heath to the circus performances of the Greenwich + Docklands International Festival, summer in London belongs to everyone. Every family can access green space, water play, live performances, and nature activities without spending anything. As a Londoner, I believe the city’s true magic is found in its public spaces, and summer is the best time to explore all of them. Get out there, discover your local area, and let London kids lead the way. London kids do not need a big budget to have a brilliant summer.
