Kew Gardens holds the largest and most diverse botanical and mycological collection in the world — over 50,000 living plants across 326 acres in southwest London — and has done so since it began life as a royal princess’s private nine-acre garden in 1759. A UNESCO World Heritage Site since 2003, it’s both one of London’s most beautiful days out and a genuine working scientific institution, with Kew’s own researchers contributing directly to global plant conservation. From the wrought-iron Palm House to a walkway suspended 18 metres up in the tree canopy, it rewards a full day far more than a quick stop.

History of Kew Gardens
Princess Augusta Founds a Nine-Acre Garden (1759)
Kew’s story begins with Augusta, Dowager Princess of Wales and mother of the future George III. In 1759, on land within the royal pleasure grounds at Kew that her family had held since 1731, she founded a nine-acre botanic garden dedicated to exotic plants — roughly the size of today’s Palm House lawn. Two years later, in 1761, the architect Sir William Chambers built the Great Pagoda within the grounds, a ten-storey chinoiserie folly that still stands today and remains one of Kew’s most recognisable landmarks.
Joseph Banks and Capability Brown
The garden’s ambitions grew rapidly. In 1768, the young botanist Joseph Banks sent seeds back to Kew while sailing with Captain Cook on HMS Endeavour, and on his return became Kew’s first unofficial director — a role he held for over 50 years, during which the collection expanded to include specimens gathered from across the growing British Empire. In 1773, the celebrated landscape architect Capability Brown carved out the Hollow Walk, now known as the Rhododendron Dell, contributing his distinctive naturalistic style to the grounds. Kew’s plant-collecting ambitions weren’t without incident: in 1787, HMS Bounty sailed for Tahiti carrying two Kew gardeners tasked with bringing back 1,000 breadfruit plants — the voyage that ended in the famous mutiny before the plants ever reached their intended destination in Jamaica.
The Palm House and Victorian Expansion
Kew passed from royal to public ownership in 1840, opening to visitors for the first time. Under the direction of Sir William Jackson Hooker and later his son Joseph Dalton Hooker, the gardens became a serious international centre for botanical science. The Palm House, built between 1844 and 1848 by the architect Decimus Burton and ironworker Richard Turner, was the first large-scale structural use of wrought iron anywhere, its hand-blown glass panes housing a genuine rainforest under London skies; it remains the world’s most important surviving Victorian glass-and-iron structure. The Temperate House followed later in the century, eventually becoming the largest Victorian glasshouse in existence — more than twice the size of the Palm House.
UNESCO and Kew Today
Kew was inscribed as a UNESCO World Heritage Site in July 2003, recognised not for a single building but for the outstanding combined value of its landscape, architecture and scientific collections built up over two and a half centuries. Today Kew is a non-departmental public body sponsored by the UK’s Department for Environment, Food and Rural Affairs, and its scientific arm continues genuinely significant conservation work — including the Millennium Seed Bank at its sister site, Wakehurst in Sussex, which safeguards seeds from thousands of the world’s most at-risk plant species.
The Treetop Walkway
One of Kew’s genuine standout attractions is the Treetop Walkway, a steel structure that rises 18 metres above the ground, weaving through the arboretum’s mature tree canopy. Designed by David Marks and Julia Barfield — the architects behind the London Eye — and opened in 2008, the walkway puts visitors at eye level with a part of the tree ecosystem almost nobody normally sees: the upper branches, where birds, insects, lichen and fungi do most of their work. A lift and gentle ramps make it fully accessible for wheelchairs and pushchairs, and it’s included in standard Kew Gardens admission at no extra cost. The walkway can close in high winds or for maintenance, so it’s worth checking Kew’s planned closures page if seeing it is a priority for your visit.

Kew Gardens Entry Price
| Ticket type | Peak (2 Sep–31 Oct), online | Off-peak (1 Nov–31 Jan), online |
|---|---|---|
| Adult | £25 | £17 |
| Concession (65+/disabled) | £23 | £15 |
| Young Person (16–29) / student | £10 | £7 |
| Child (4–15) | £2 | £2 |
| Under 4 | Free | Free |
| Universal/Pension Credit | £1 | |
Booking online is meaningfully cheaper than paying at the gate, and Kew also runs £10 Tuesdays every Tuesday from 8 September to 29 December 2026, offering standard adult admission for £10 on those days specifically. £1 tickets are available year-round for anyone receiving Universal Credit, Pension Credit or several other named benefits, with up to four additional guest tickets per holder.
Opening Hours
Hours vary by season, generally running 10am to between 4pm (deep winter) and 7pm (summer), with last entry an hour before closing. Individual attractions inside the gardens — glasshouses, the Treetop Walkway, Kew Palace — often close earlier than the gardens themselves, so it’s worth checking Kew’s specific attraction opening times if one particular building is the main reason for your visit, rather than assuming everything stays open until the gates close.
Kew Gardens What’s On
Kew runs a genuinely packed seasonal events calendar beyond the permanent collection: an Orchid Festival each February–March inside the Princess of Wales Conservatory, summer evening concerts on the Great Broad Walk lawns, and family activity trails through the school holidays. The headline seasonal event is Christmas at Kew, the UK’s original illuminated light trail, returning for 2026 from 13 November 2026 to 3 January 2027. It’s a separate, timed, ticketed evening event run after the gardens close for the day (entry from 4.20pm) — daytime admission and concession rates don’t carry over to it, and it’s Kew’s single most in-demand event, so booking well ahead is genuinely worth it if you want a specific date.
Car Park at Kew Gardens
Kew’s own car park sits on Ferry Lane, near Brentford Gate (postcode TW9 3AF), and costs £10 per day, payable at a card-only meter on-site or via the PayByPhone app. Blue Badge holders park free in designated disabled bays. The car park is limited to around 300 spaces and fills quickly on weekends and school holidays; an overflow Herbarium car park opens on the busiest peak-season weekends once Ferry Lane is full. There’s no car park at Victoria Gate, Lion Gate or Elizabeth Gate, so if you’re driving, plan to enter via Brentford Gate. Kew sits inside the Ultra Low Emission Zone (ULEZ), so check current ULEZ charges before driving in if your vehicle might be affected; it is not inside the Congestion Charge zone.
Getting There by Tube and Train
Kew Gardens station (District line and London Overground) is the simplest option, around 500 metres — roughly a 5-minute walk — from Victoria Gate, the main visitor entrance. Kew Bridge station, served by South Western trains from London Waterloo, is about 800 metres from Elizabeth Gate but has no step-free access; Richmond station offers a step-free alternative, with a short bus ride (route 65) on to Lion or Victoria Gate.
Restaurants at Kew Gardens
Kew has five main on-site dining venues, each requiring a valid garden admission ticket to reach: the Botanical Brasserie near Victoria Gate for formal dining and Kew’s well-known afternoon tea; the Pavilion Bar and Grill out in the arboretum, useful after tackling the Treetop Walkway; the Orangery near Elizabeth Gate for lighter meals and coffee; the family-oriented Family Kitchen near Brentford Gate; and the Victoria Plaza Café for a quick coffee near the main entrance. Picnics are allowed across most of the grounds (though not inside the cafés themselves), and the Arboretum and the area around the Waterlily Pond are popular picnic spots if you’d rather bring your own food.
If you’re looking beyond the gates, Kew village itself, just outside Victoria Gate, has a small but well-regarded cluster of independent cafés and restaurants worth considering for dinner after an afternoon in the gardens.
Weddings and Private Events at Kew
Kew is a genuine wedding and events venue in its own right, hiring out spaces including the grand, glass-roofed Orangery (capacity up to 400 standing), the illuminated Princess of Wales Conservatory for evening drinks receptions, the historic Nash Conservatory (relocated to Kew from Buckingham Palace in 1836), and the more intimate Cambridge Cottage, a former royal residence within the grounds. As a UNESCO World Heritage Site, Kew requires couples and event organisers to book from its own approved supplier list for catering, production and decoration. Costs vary considerably by space and season, but couples should budget a minimum of roughly £12,000 for venue hire and catering combined as a starting point, with a detailed quote available directly from Kew’s venue hire team.
How Long to Allow
Kew genuinely rewards a full day — at 326 acres, it’s considerably larger than most visitors expect, and the walk between the Palm House, Temperate House, Treetop Walkway and Great Pagoda alone covers real distance. Three to four hours is the minimum for a satisfying visit taking in the main glasshouses and a walk through the arboretum; a full day allows time to properly explore the Princess of Wales Conservatory, the art galleries and the quieter corners of the grounds.
Accessibility
Kew is largely step-free, with mobility scooters and wheelchairs available to borrow (subject to availability, best booked in advance), accessible toilets throughout the grounds, and lift access to the Treetop Walkway. Concessionary tickets are available for disabled visitors, and registered blind or partially-sighted visitors, along with their essential companion, receive free entry.
Managing Body
Kew Gardens is managed by the Royal Botanic Gardens, Kew, a non-departmental public body sponsored by the UK’s Department for Environment, Food and Rural Affairs (Defra), operating as a working scientific institution alongside its role as a visitor attraction.
