Best Hidden Gems in London
Written by UK Hidden Gems Editorial

The best hidden gems in London are Camley Street Natural Park, Chelsea Physic Garden, Platform 9¾ at King’s Cross, The Viktor Wynd Museum of Curiosities, St. Margaret’s Church, Hornchurch Pill Box, Traffic Light Tree and Isabella Plantation.
London hides its best surprises down side streets and behind station barriers, in walled gardens and quiet corners of its great parks. Beside the canal at King's Cross, Camley Street Natural Park packs a pond, reedbed and meadow into a couple of acres, while a short walk away visitors run at the barrier of Platform 9¾.
In Chelsea, the walled Physic Garden shelters tender plants founded on 17th-century apothecary beds, and in Hackney the Viktor Wynd Museum crowds skulls and oddities into two floors. There is the parish church of the Commons at St.
Margaret's beside Westminster Abbey, wartime pillboxes at Hornchurch, a sculpture of working traffic lights at Blackwall, and the blazing azaleas of the Isabella Plantation inside Richmond Park. Some are free and open every day, others ticketed or charged, and each rewards the small effort of seeking it out.
Here are eight of the best hidden gems to seek out in London.
Camley Street Natural Park

Camley Street Natural Park is a small urban nature reserve on a strip of land between the Regent's Canal and the street at King's Cross, run by the London Wildlife Trust. Once a coal drop for the railways, it opened as a reserve in 1985 and now packs a pond, reedbed, meadow and woodland into a couple of acres, with a pond-dipping platform and hundreds of plant species.
A modern visitor centre and cafe opened in 2022, and entry is free. Kingfishers, woodpeckers and dragonflies are among the wildlife seen here, so bring patience and watch the water.
Chelsea Physic Garden

Chelsea Physic Garden is a walled botanic garden beside the Thames in Chelsea, founded in 1673 by the Society of Apothecaries to grow medicinal plants. High brick walls hold in a warm pocket of air, letting tender plants thrive that would struggle elsewhere in the city.
Inside are thousands of species of medicinal, edible and useful plants laid out in beds, along with an old rock garden and glasshouses, across about four acres tucked behind the walls off Royal Hospital Road. It is easy to miss from the street, so look for the entrance and step through into its quiet world.
Platform 9¾ at King’s Cross

Platform 9¾ at King’s Cross is a photo spot and shop inside King's Cross station, drawn from the Harry Potter stories where young wizards run at a barrier to reach the school train. A luggage trolley has been set half into a brick wall as though vanishing through it, and staff hand visitors a house scarf and wand and flick the scarf for the shot.
Right beside it is a themed shop selling wands, robes and other goods. It sits outside the ticket barriers, so no train ticket is needed, and taking your own photo is free.
Expect a queue at busy times.
The Viktor Wynd Museum of Curiosities

The Viktor Wynd Museum of Curiosities is a small, privately run cabinet of curiosities on Mare Street in Hackney, home to the Last Tuesday Society. Two crowded floors hold taxidermy, skulls, shrunken heads, occult and erotic oddities and surrealist art, deliberately jumbled in the style of a 17th-century wonder-room, with an absinthe bar in the basement.
Entry is charged, and it opens from afternoon into the evening on most days of the week. Named after its founder, the artist Viktor Wynd, it is a strange, adults-oriented spot, so check the opening times before you go.
St. Margaret’s Church

St. Margaret’s Church stands just north of Westminster Abbey, on the Parliament Square side, within the same World Heritage Site in the heart of Westminster.
It has been the parish church of the House of Commons since 1614, a Perpendicular Gothic building of the late 15th and early 16th centuries, with an early-16th-century Flemish east window linked to Catherine of Aragon. Sir Walter Raleigh is buried here, and Samuel Pepys, John Milton and Winston Churchill were among those married here.
Free to enter and still a working church beside the Abbey, it is easily overlooked by the crowds next door.
Hornchurch Pill Box

Hornchurch Pill Box is one of the wartime defences left from RAF Hornchurch, a fighter airfield in the Battle of Britain, now the open ground of Hornchurch Country Park. Scattered around the old airfield's edge are hexagonal concrete pillboxes and rarer Tett turrets, small one-man revolving posts sunk into the ground.
Several stand out in the park where they can be seen and reached on the paths, and a visitor centre nearby tells the story of the airfield. Bring a map or follow the trails, and look out for the low concrete shapes among the grass.
Traffic Light Tree

Traffic Light Tree is an eight-metre sculpture made from 75 sets of working traffic lights arranged to look like a tree, standing on a road island on Trafalgar Way at Blackwall in east London. The lights cycle through programmed patterns rather than directing any traffic.
French artist Pierre Vivant created it in 1998, and it first stood near Canary Wharf before being moved to its present spot by the old Billingsgate Market, where it was relit in 2014. Free to see from the pavement at any time, it is a roadside piece rather than a park attraction, so take care of the traffic.
Isabella Plantation

Isabella Plantation is a woodland garden hidden within Richmond Park in south-west London, fenced off from the park's deer and laid out around ponds and little streams. It is celebrated for its azaleas and rhododendrons, which blaze with colour in late April and May, reflected in the still water of the ponds.
Camellias and magnolias flower earlier, and paths wind through the trees the year round. Free to enter and open every day, it is a quiet garden within the wider park.
Come in spring for the colour, though it rewards a visit in any season.
FAQs
What are the best free hidden gems in London?
Several cost nothing to enjoy. Camley Street Natural Park, St. Margaret's Church and the Isabella Plantation are all free to enter, and the Traffic Light Tree can be seen from the pavement at any time. Taking your own photo at Platform 9¾ is also free.
Do I need a ticket for Platform 9¾?
No train ticket is needed, as the photo spot sits outside the station's ticket barriers. Taking your own photo is free, though the themed shop beside it sells wands, robes and other goods should you want a souvenir.
When is the best time to visit the Isabella Plantation?
Late April and May bring the azaleas and rhododendrons into full colour, reflected in the ponds. Camellias and magnolias flower earlier, and the paths are open every day the year round, so it rewards a visit in any season.
Conclusion
From a canalside nature reserve at King's Cross to a woodland garden deep in Richmond Park, London's best hidden gems reward anyone willing to look past the obvious sights. You can pose at the barrier of Platform 9¾, wander the walled beds of the Chelsea Physic Garden, step into the roomful of oddities at the Viktor Wynd Museum, or slip into St.
Margaret's beside the Abbey. Out in the edges of the city, wartime pillboxes stand in the Hornchurch grass and a tree of traffic lights blinks at Blackwall.
Some are free and open daily, others charged or limited to set hours, so a quick check before you set out pays off. Wherever you start, these are the best hidden gems to seek out in London.
