From palace concerts and open-air Shakespeare to food festivals and garden parties, outdoor adventures await, says Chris Johnson.

London in the summer belongs outside. Parks become dining rooms, palace courtyards turn into concert halls, museum gardens fill with music and storytelling, and Shakespeare somehow feels even more magical performed beneath open skies. This is the season when the capital stretches out, slows down and invites all of us to make the most of the warmer days, longer evenings and sultry nights.
Whether it is discovering science in South Kensington, introducing younger audiences to their first outdoor theatre performance, or picnicking before a palace concert, the city comes alive with open-air experiences to revel in.
One of the month’s most joyful family events arrives courtesy of The Great Exhibition Road Festival (6-7 Jun), which transforms this part of South Kensington into a playground of science, art and imagination.

Led by Imperial College London and joined by institutions including the Natural History Museum, Science Museum and the V&A South Kensington, this free festival celebrates 175 years since the Great Exhibition of 1851 with talks, workshops and hands-on activities for all ages.
For families, the standout is the Family Fun Zone on East Albert Lawn in Kensington Gardens, where children can build rocket mice, design the perfect paper aeroplane, become polar explorers in Antarctica and even help create blood-themed art installations. There are also relaxed sessions available for those who are neurodivergent plus plenty of space for picnics between activities. It is one of the capital’s best free weekends of the summer.

Music lovers, meanwhile, have no shortage of open-air performances to choose from. Live at Chelsea (10-14 Jun) returns to the grounds of the Royal Hospital Chelsea, where concerts unfold against one of London’s most elegant historic backdrops. This year’s stellar line-up sees Holly Johnson, Tony Hadley and Heaven 17 bring a welcome dose of 1980s glamour to proceedings.
Further south, Hampton Court Palace Festival (10-20 Jun) remains one of London’s most atmospheric music events. With just 3,000 seats per show, concerts inside Henry VIII’s former home feel unusually intimate. Guests arrive early to picnic in the East Front Gardens before artists including David Gray, Nile Rodgers & CHIC, Sophie Ellis-Bextor and Elvis Costello take to the stage in the Base Court. It is history, music and summer evening theatre all at once.
Fun in the sun
Adding a playful note to the season is a drop-in activity that appeals as much to families as it does to competitive friends. Minigolf by Craig & Karl (to 27 Sep) at Montgomery Square in Canary Wharf brings bold colour and graphic design to the classic game in an iconic free-to-play nine-hole course designed by illustrators Craig Redman and Karl Maier. Clubs and balls are provided on site.

For something a little sweeter, Ben & Jerry’s Sundaes in the Park Festival returns to Chiswick House & Gardens on 13 June with live music, unlimited ice cream and festival energy dialled firmly towards fun. Headlined by Pixie Lott, the day combines music stages, workshops, cabaret and a strong social mission supporting refugee charities. Festival-goers can sample unlimited scoops all day while enjoying one of the city’s loveliest green spaces.
Food takes centre stage once again with Taste of London in The Regent’s Park (17-21 Jun), five days of open-air feasting that has become one of the capital’s great summer rituals. More than 30 restaurants and some 130 dishes from the city’s top talent turn the park into a giant garden party.
Families can graze their way through everything from dumplings and tacos to fine- dining tasting plates, while older visitors can enjoy chef masterclasses, barbecue cooking schools and cocktail terraces. There are demonstrations from chefs including Helen Graham, Melissa Thompson and Big Zuu, alongside tastings and interactive workshops. It is impossible to leave hungry.
A Cultural Summer
Just a few days later, one of Shakespeare’s most beloved plays can be seen in what is arguably its most natural setting with the arrival of A Midsummer Night’s Dream at Regent’s Park Open Air Theatre (20 Jun-18 Jul). There may be no better play for an outdoor stage. Directed by Atri Banerjee, this new production brings lovers, fairies, Puck and Bottom to life in the theatre’s magical setting, where dusk, birdsong and rustling leaves become part of the production itself.
Banerjee calls it ‘the play best suited to the park’s surroundings’, and it’s easy to see why. As the fairy kingdom emerges beneath the trees, Shakespeare feels less staged and more discovered. It is an deal family theatre outing and is one of the highlights of a season packed with delights.

South of the river in Forest Hill, the glorious Horniman Museum & Gardens celebrates its 125th anniversary on 27 June with a huge free birthday party across its gardens. Few places feel as suited to summer as the Horniman, and in this milestone year visitors are treated to an especially lively programme of music, crafts and family-friendly games.
There will be bouncy castles, storytelling tents, ‘hedgehog highway’ sign making, object handling, creative workshops, dance performances and giant collaborative artworks to enjoy, alongside food stalls, trails and even ‘Smallympics’: eccentric garden games with trophies and medals included. It is the perfect celebratory tribute and just the kind of wonderfully British outdoor celebration families remember for years.
Finally, for those looking for a complete change of pace, the Marylebone Music Festival (15-21 Jun) transforms the usually serene and tranquil Manchester Square Gardens into an intimate open-air concert venue in the heart of the capital. Now in its 11th year, the festival brings orchestral music from the likes of the Royal Academy of Music outdoors, welcoming seasoned classical audiences, curious first-time listeners and families alike. It is one of London’s loveliest hidden summer traditions: music drifting through garden squares under the night sky.
London in summer means culture rarely stays indoors. It spills into parks, courtyards and rooftops, into museum lawns and secret squares, and into long evenings that seem designed for one more encore, one more stirring performance beneath the stars.
