21 Brilliant Things to Do in London in June 2026
June is one of the best months to be in London.
The days are long, parks are at their greenest, outdoor events fill the calendar and the city seems to spend more time outside than in. Rooftops come alive, riverside walks become evening rituals and some of London's biggest annual events return for the start of summer.
Whether you're visiting London for the first time or looking for new ways to enjoy the city, June offers something for everyone. From major festivals and royal celebrations to hidden gardens and sunset viewpoints, here are 21 brilliant things to do in London this June.
1. Explore London's Secret Gardens During London Open Gardens
For one weekend each year, some of London's most beautiful hidden gardens open to the public.
London Open Gardens gives visitors access to rooftop gardens, private squares, community spaces and historic green areas that are usually closed.
It's one of the best opportunities to see a side of London most people never discover.
2. Visit Kew Gardens in Full Bloom
June is one of the most spectacular times to visit Kew Gardens.
The world's most famous botanical garden bursts into colour as flowers, glasshouses and tree-lined pathways come alive.
Allow several hours because there's far more to see than most visitors expect.
3. Watch the Trooping the Colour Celebrations
One of Britain's most famous royal traditions takes place in June.
The King's Birthday Parade, better known as Trooping the Colour, features hundreds of soldiers, military bands and ceremonial pageantry in central London.
The flypast above Buckingham Palace is often one of the highlights.
4. Spend an Evening at West End Live
Theatre lovers should keep an eye on West End Live.
The event brings performances from some of London's biggest musicals to Trafalgar Square, allowing visitors to enjoy world-class theatre performances for free.
It's one of the city's most popular summer events.
5. Explore the London Festival of Architecture
Throughout June, London's architecture takes centre stage.
The London Festival of Architecture includes talks, exhibitions, walking tours and events that help visitors understand how the city has evolved over time.
Even casual visitors often discover fascinating corners of London through the festival.
6. Enjoy a Picnic in Regent's Park
Not every great London experience requires a ticket.
Regent's Park is particularly beautiful in June, with rose gardens, open lawns and plenty of space for a summer picnic.
Pick up food from a bakery or market and spend an afternoon outdoors.
7. Visit Taste of London
Food lovers should keep Taste of London firmly on their radar.
The festival brings together some of the city's best restaurants, chefs and food experiences in one place.
It's a fantastic way to sample dishes from multiple restaurants without needing multiple reservations.
8. Watch Shakespeare Under the Stars
The Regent's Park Open Air Theatre becomes one of London's most magical venues during summer.
Watching a performance surrounded by trees as daylight slowly fades is a uniquely London experience.
Even people who aren't regular theatre-goers often love it.
9. Walk Through Little Venice
Little Venice feels surprisingly peaceful for central London.
Canals, colourful narrowboats and waterside cafés create an atmosphere that's very different from the busy city centre.
June weather makes it the perfect time for a leisurely walk.
10. Watch Sunset from Primrose Hill
Few places offer a better June sunset than Primrose Hill.
As the sun begins to set behind London's skyline, locals gather on the hill with snacks, drinks and picnic blankets.
It's one of the city's most iconic summer traditions.
11. Explore Greenwich on a Sunny Day
Greenwich offers enough attractions for an entire day.
Combine:
Greenwich Park
The Royal Observatory
Cutty Sark
Greenwich Market
Riverside walks
The skyline views from the hill remain some of the best in London.
12. Visit Borough Market
Summer is one of the best times to explore Borough Market.
Fresh produce, pastries, international street food and artisan treats make it one of London's most exciting food destinations.
Arrive early if you want to avoid the biggest crowds.
13. Discover Hampstead Heath
Hampstead Heath offers a more natural side of London.
Unlike the formal Royal Parks, the Heath feels wild and untamed.
Parliament Hill also provides one of the best panoramic views of the city.
14. Explore the South Bank
The South Bank always feels lively in June.
Street performers, food stalls, riverside bars and cultural attractions create a vibrant atmosphere throughout the area.
Walking between Westminster Bridge and Tower Bridge remains one of the best free activities in London.
15. Visit the Kyoto Garden
Hidden inside Holland Park, the Kyoto Garden is one of London's most peaceful places.
Waterfalls, koi carp, stone lanterns and peacocks make it feel surprisingly far removed from the city around it.
It's particularly beautiful during summer.
16. Spend an Evening at a Rooftop Bar
June officially marks rooftop season in London.
Popular options include:
Sky Garden
Madison
Seabird
The Garden at 120
Forza Wine
Watching the skyline change colours as the sun sets is one of the best ways to experience the city.
17. Take a Thames Riverside Walk
The Thames is at its best during summer.
Some excellent routes include:
Westminster to Tower Bridge
Greenwich riverside
Richmond riverside
South Bank
The longer daylight hours make evening walks especially enjoyable.
18. Visit Richmond Park
Richmond Park feels more like countryside than city.
The park's famous deer, ancient trees and open landscapes provide a welcome escape from central London.
June is one of the best months to explore it.
19. Discover St Dunstan in the East
This hidden public garden sits inside the ruins of a bomb-damaged church.
Surrounded by modern skyscrapers, it offers one of the most unique settings anywhere in London.
Many visitors walk straight past without realising it's there.
20. Enjoy Afternoon Tea
June is the perfect time to enjoy one of Britain's most famous traditions.
Whether you choose The Ritz, Fortnum & Mason, Claridge's or a smaller independent tea room, afternoon tea remains one of London's most enjoyable experiences.
The combination of elegant surroundings and summer sunshine makes it feel especially special.
21. Take a Day Trip Beyond London
Long June days make day trips particularly rewarding.
Popular options include:
Windsor
Cambridge
Oxford
Brighton
Canterbury
The Cotswolds
Each can be reached from London and offers a completely different perspective on England.
Why June Is One of London's Best Months
There are very few times of year when London feels as balanced as June.
Spring flowers are still visible, summer events are beginning, daylight lasts late into the evening and outdoor spaces become central to city life.
The weather is often warm without becoming overwhelming, making it ideal for sightseeing, walking and exploring.
For many Londoners, this is the month when the city truly comes alive.
Final Thoughts
London always offers plenty to do, but June feels different.
The parks are greener, the evenings are longer and the city spends much of its time outdoors.
Whether you're exploring hidden gardens, attending major festivals, enjoying riverside walks, discovering rooftop views or simply relaxing in one of London's beautiful parks, June offers some of the best experiences the city has all year.
And if you can only visit London during one summer month, June makes a very strong case for being the perfect choice.
