A City That Loves Families

London truly comes alive for families during the summer months, and 2026 is shaping up to be an exceptional year for visitors with children in tow. London in July 2026 is when the capital truly comes into its own, with long summer days, a lively festival atmosphere and a packed calendar of events. It's one of the best times to visit, with no shortage of things to do.

Whether you're visiting for a weekend or an entire fortnight, there's something magical about exploring this city through your children's eyes. Here's our guide to the very best family experiences happening right now.

Theatre Magic: Kids Week and West End Wonders

One of the highlights of summer in London is the legendary Kids Week. Now in its 25th year, Kids Week offers children aged 17 and under the chance to attend top shows for free when accompanied by an adult paying full price. Each paying adult can also purchase up to two additional children's tickets at half price, all with no booking fees.

Tickets went on sale on 9 June 2026 via Official London Theatre. Alongside theatre performances, Kids Week features a lively programme of workshops and activities, giving young audiences a behind-the-scenes look at how productions are created.

Disney musicals like Frozen and The Lion King are great kids' theatre shows, alongside other family-friendly hits like Wicked and Harry Potter and the Cursed Child. These shows have run in the West End for multiple years and continue to delight audiences of all ages.

For something truly special, Alice in Wonderland returns to London for a limited summer season in 2026, playing at Riverside Studios from 16 July to 2 August, before transferring to Soho Theatre Walthamstow from 5 to 16 August.

Museums Bursting with Summer Activities

London's museums pull out all the stops during the school holidays. The London Transport Museum is powering up for an electric summer from 21 July to 2 September 2026. Families can enjoy activities exploring the electrical innovations that have powered London's public transport for more than one hundred years.

Over at the Natural History Museum, there's the Dino Disco for Kids, a headphone disco located in the Hintze Hall that's fun for all the family, taking place on 31 July from 7pm to 9pm.

The Royal Society Summer Science Exhibition returns from 30 June to 5 July 2026, offering a free, week-long celebration of cutting-edge research. Bringing together leading scientists and engineers from across the UK, the exhibition features 13 interactive displays alongside a dynamic programme of talks, demonstrations and hands-on activities for all ages.

Outdoor Adventures and Free Fun

Head to Summer Rocks 2026 at Wembley Park for a free season of music, art, food, sport and family fun all in one place. Expect live music, pop-up events, outdoor activities and plenty of places to stop for a bite to eat.

There's a free minigolf experience at Canary Wharf running until 27 September. Set in Montgomery Square, the colourful 9-hole course has been designed by artists Craig Redman and Karl Maier, making it a unique and creative activity for kids and adults. There's no need to book—simply turn up and collect your clubs.

Summer in the Square at Portman Square Garden opens to the public from 7th to 12th July with free Wimbledon screenings, food pop-ups, wellness sessions, family activities, theatre workshops, poetry, live music and cultural events.

Gardens in Bloom

Kew Gardens hosts the Tom Gates Epic Adventure from 18th July to 31st August, where families can create, roam and play in an activity hub inspired by the beloved book series. There's also a 'Totally Terrific Tree Trail' included with entry.

Also at Kew Gardens, catch an outdoor production of Wind in the Willows from 18th to 23rd July. Set against the backdrop of the lake, this performance is filled with colourful characters, music, song and laughter, with tickets from £18.90.

Chelsea Physic Garden offers lots of family events such as crafternoons, chocolate making, soap making and mini garden making throughout July and August.

Practical Tips for Families

Children under 11 travel for free on London buses and the Tube when accompanied by a paying adult. It's an efficient and budget-friendly way to travel between museums and the West End.

London offers incredible free attractions, including the Young V&A, Natural History Museum, and Science Museum. You can also explore the Royal Parks, like the Diana Memorial Playground in Hyde Park, which is free and world-class.

Buckingham Palace opens to the public from 9 July to 27 September 2026, inviting visitors to take a self-guided tour of its lavish State Rooms and beautiful gardens.

Make It Memorable with a Local Guide

While London is wonderfully navigable for independent exploration, there's something special about discovering the city's hidden corners and fascinating stories through the eyes of someone who knows it intimately. A local guide can transform a standard sightseeing trip into an adventure tailored to your family's interests—whether that's hunting for Harry Potter filming locations, uncovering secret royal histories, or finding the best playgrounds between museum stops.

Many popular summer holiday activities in London can book up quickly during the school holidays, so it's worth reserving ahead where possible—even for free attractions.

This summer, London awaits your family with open arms and an extraordinary calendar of events. Happy exploring!
