12 Secret Gardens in London | Beautiful Hidden Gems
London is famous for its grand parks, historic squares and spectacular royal gardens, but some of the capital’s most beautiful green spaces are much easier to miss. Tucked behind old churches, hidden inside residential neighbourhoods, sitting above city streets or enclosed by historic walls, these quieter gardens offer a very different side of London.
In fact, London is almost half green or blue, with parks, gardens, woodlands, waterways and nature reserves spread throughout the capital. The city’s hidden green spaces can provide a welcome escape from busy streets without requiring you to travel far from central London.
If you’re looking for somewhere peaceful to read a book, take photographs, enjoy flowers or simply escape the crowds for an hour, these 12 secret gardens in London are well worth discovering.
1. St John’s Lodge Garden
Hidden inside Regent’s Park, St John’s Lodge Garden is one of London’s most atmospheric little gardens. It is easy to overlook because the much larger Regent’s Park surrounds it, but stepping through its entrance feels like entering an entirely different space.
The Royal Parks describes it as London’s “best kept secret garden”, and the garden was designed as a place for meditation. Its Arts and Crafts character can be seen in the intimate layout, mixed borders, ornamental sculpture and carefully shaped yew hedges. Clematis and honeysuckle cover the entrance arbour, while secluded recesses provide quiet places to sit.
Late spring is particularly appealing, when the planting is at its best, although the garden is a worthwhile stop whenever you want a peaceful break from the busier parts of Regent’s Park.
Best for: Quiet walks, photography and peaceful moments
Location: Regent’s Park
Entry: Free
2. Chelsea Physic Garden
Chelsea Physic Garden is one of London’s most fascinating hidden gardens, particularly if you enjoy plants, history and unusual botanical collections. Established in 1673 by the Worshipful Society of Apothecaries, it was originally created as a training ground for apprentices. Today, it remains one of the capital’s most distinctive botanical spaces.
Behind its walls you’ll find more than 4,500 medicinal, edible and useful plants across four acres. There are historic glasshouses, specialist plant collections and quiet paths that make the garden feel surprisingly removed from the surrounding Chelsea streets. The garden is also home to one of Europe’s oldest rock gardens.
This is a particularly good choice if you want more than somewhere simply to sit on the grass. You can spend time exploring the history of medicinal plants, discovering unusual species or simply enjoying the atmosphere of this historic enclosed garden.
Best for: Plant lovers, history and botanical photography
Location: Chelsea
Entry: Paid
3. Postman’s Park
Postman’s Park is one of the easiest secret gardens in central London to miss. Tucked away among the buildings of the City, it provides a surprisingly peaceful pocket of greenery just a short walk from St Paul’s Cathedral.
The garden first opened as a public park in 1880 and became popular with workers from the nearby General Post Office, which gave it its name. Today, one of its most distinctive features is the Watts Memorial, created in 1900 to commemorate ordinary people who died while saving the lives of others.
The garden is small enough to explore quickly but atmospheric enough to make you want to stay. Seasonal planting, mature greenery and benches provide a welcome place to pause during a day exploring the City.
Best for: History, quiet breaks and central London walks
Location: Near St Paul’s
Entry: Free
4. Kyoto Garden
Kyoto Garden may not be completely unknown, but it remains one of the most tranquil hidden corners of West London. Tucked inside Holland Park, the Japanese-style garden feels remarkably different from the surrounding city.
The garden features carefully maintained planting, Japanese-style landscaping, a pond, waterfalls and colourful koi. Peacocks also wander around Holland Park, adding another distinctive element to the experience. Spring is particularly attractive when cherry blossom appears.
Although it has become increasingly popular with photographers and visitors, Kyoto Garden still provides moments of calm if you visit at a quieter time. It is an excellent place for a slow walk rather than somewhere to rush through.
Best for: Japanese gardens, photography and peaceful walks
Location: Holland Park
Entry: Free
5. The Dell
Hyde Park is hardly a secret, but tucked within this enormous Royal Park is a much quieter garden that many visitors overlook: The Dell. Described by the Royal Parks as a secluded “garden-within-a-garden”, it provides a more naturalised experience than the formal areas of Hyde Park.
The Dell sits close to the Serpentine and features a cascading waterfall, an alpine meadow and Nannie’s Lawn. Visit in spring and you can see a display of early flowers, while the surrounding landscape provides a habitat for wildlife.
It is particularly good for anyone who wants to experience a wilder side of central London. Instead of formal flower beds and manicured lawns, The Dell offers a softer landscape where you can slow down and enjoy nature.
Best for: Nature, spring flowers and quiet walks
Location: Hyde Park
Entry: Free
6. Cloth Fair Hidden Garden
Hidden beside the historic St Bartholomew the Great in Smithfield, Cloth Fair Hidden Garden is exactly the kind of place that gives London its reputation for unexpected discoveries. The garden occupies a small space beside one of the capital’s oldest churches.
The site has had several lives over the centuries, including farmland, a priory garden and a school building. After a period of neglect, local volunteers helped restore the garden in 2017, transforming it into a greener space designed to attract pollinators and stimulate the senses.
Its combination of history and planting makes it particularly appealing. You can visit the church and surrounding historic streets before stepping into this much quieter little garden.
Best for: History lovers, hidden gems and photography
Location: Bartholomew Close, City of London
Entry: Check access arrangements before visiting
7. The Barbican Wildlife Garden
The Barbican is famous for its brutalist architecture, arts centre and concrete walkways, but it also hides a surprisingly rich wildlife garden. The Barbican Wildlife Garden demonstrates just how much nature can flourish in the middle of one of London’s most heavily built-up areas.
The garden contains ponds, an orchard, meadow areas and a bird hide, and the RHS notes that it supports around 300 species of wildlife. That makes it a particularly interesting destination for anyone who wants to see how urban gardening can create habitats for plants and animals.
It is a brilliant contrast to the surrounding architecture. Rather than simply providing ornamental planting, the garden has a strong emphasis on biodiversity, making it one of the more unusual green spaces on this list.
Best for: Wildlife, urban nature and photography
Location: Barbican, City of London
Entry: Check opening/access arrangements
8. Ismaili Centre Roof Garden
The Ismaili Centre Roof Garden is one of London’s more unusual hidden gardens because it sits above street level in South Kensington. Designed around the principles of Islamic garden design, it offers a calm and carefully structured space away from the traffic and crowds below.
At the centre of the garden is a fountain, while geometric planting and hard landscaping create the four-part structure known as a chaharbagh. The design draws on traditions from Muslim civilisations and uses water, greenery and symmetry to create a contemplative environment.
The rooftop setting gives the garden an additional sense of escape. If you’re exploring the museums around South Kensington, this can provide a very different kind of experience from the area’s busy streets.
Best for: Architecture, garden design and quiet reflection
Location: South Kensington
Entry: Check opening arrangements
9. Fenton House Garden
Fenton House in Hampstead is home to a beautiful walled garden that feels a world away from the busy streets outside. The National Trust describes it as an oasis of calm just steps from Hampstead High Street.
The garden includes a rose garden, colourful borders, a formal lawn and an orchard containing 32 varieties of apple. Its enclosed character gives it a particularly intimate atmosphere, making it a lovely place for visitors who prefer traditional gardens to large open parks.
It is worth combining a visit with a walk around Hampstead’s historic streets. Together, the house, garden and surrounding neighbourhood make for a relaxed half-day outing away from the more heavily visited central London attractions.
Best for: Traditional gardens, roses and Hampstead walks
Location: Hampstead
Entry: National Trust admission/arrangements apply
10. Earls Court Square Garden
Surrounded by elegant Victorian architecture, Earls Court Square contains a beautifully planted central garden that is easy to miss if you are simply passing through the neighbourhood. It was originally laid out as part of the Edwardes Estate in the 1870s.
The garden went through a period of decline after the Second World War before local residents helped rejuvenate it. Today, it forms an important part of the square’s character and includes a central lawn and children’s play area.
It is a good example of London’s historic garden squares, many of which remain tucked behind railings and residential streets. While access can differ from completely open public parks, the square is worth seeking out for its architecture and greenery.
Best for: Victorian architecture and garden-square enthusiasts
Location: Earls Court
Entry: Check access arrangements
11. Doddington and Rollo Community Roof Gardens
For something completely different, head to Battersea and look upwards. The Doddington and Rollo Community Roof Gardens occupy the roof of a former car park and turn an otherwise unlikely urban location into a series of productive garden spaces.
The rooftop contains five garden rooms with ornamental plants, edible crops, trees and a composting area. There is also a kitchen garden, raised beds and a pizza oven, while an old metal staircase has been reused as a trellis. The RHS notes that the garden inspired the RHS Chelsea Flower Show Sanctuary Garden in 2023.
This is one of the best gardens on the list for seeing how Londoners are transforming unconventional urban spaces. It is less about grand historic landscaping and more about community, food growing and creative urban gardening.
Best for: Urban gardening, community projects and inspiration
Location: Battersea
Entry: Check access arrangements
12. Victoria Tower Gardens
Victoria Tower Gardens may be more open than some of the tiny hidden gardens on this list, but its location makes it surprisingly easy to overlook. Sitting beside the Thames beneath the Palace of Westminster, it provides one of the more peaceful riverside escapes in central London.
The Grade II-listed public garden opened as a formal green space in 1914. Today, its lawns, riverside path and planted areas provide places to sit and enjoy views towards the Palace of Westminster, Lambeth Bridge and the London Eye.
It is particularly lovely when you want to combine sightseeing with a quiet break. Instead of looking at Westminster only from the busy streets around Parliament Square, you can sit beside the river and take in the skyline from a much calmer setting.
Best for: Riverside views, sightseeing and picnics
Location: Westminster
Entry: Free
Why Visit London’s Secret Gardens?
One of the best things about London’s hidden gardens is the variety. Some are centuries old, while others are community projects created on rooftops or in unexpected corners of the city.
They also demonstrate how diverse London’s green spaces can be. The capital has formal Victorian squares, Japanese gardens, historic botanical collections, wildlife habitats, rooftop gardens and small churchyard oases. London Gardens Trust also highlights numerous lesser-known gardens, churchyards, community gardens and small parks through its self-guided walking routes.
For visitors, these gardens offer something that London’s major attractions often cannot: a chance to slow down. You don’t necessarily need a full day to enjoy them. Many can be combined with nearby museums, historic buildings, shopping streets or walking routes.
Final Thoughts
London’s famous parks are certainly worth visiting, but some of the capital’s most memorable green spaces are the ones you have to look a little harder to find.
From the tranquil St John’s Lodge Garden and historic Chelsea Physic Garden to the atmospheric Postman’s Park, peaceful Kyoto Garden and innovative Doddington and Rollo Community Roof Gardens, these places reveal a quieter side of London.
If you’re planning a London day out, consider adding one of these gardens to your itinerary. You may discover that one of the city’s best escapes is hiding just around the corner.
Tip: Some of the gardens on this list have restricted or seasonal access, particularly private, community and rooftop gardens. Always check the relevant garden’s current opening arrangements before making a special journey. London’s annual Open Gardens programme is another excellent way to access normally closed or hidden green spaces; the 2026 programme includes more than 120 gardens and other green spaces.
