Kew Gardens

The World’s Most Important Garden Is in Zone 3

The Royal Botanic Gardens, Kew holds the world’s largest collection of living plants. It also runs the Millennium Seed Bank at Wakehurst in West Sussex, which has banked seeds from over 40,000 plant species from 190 countries, representing roughly 15 percent of the world’s wild plant species. Some of those seeds belong to plants that are now extinct in the wild. None of this appears on most tourist itineraries, which tend to focus on the Victorian glasshouses and the ornamental lawns. Both are worth seeing, but treating Kew as a scenic park rather than an active scientific institution is to miss most of what makes it interesting.

The seed vault at Wakehurst is built with half a metre of concrete lining and designed to survive floods, explosions, and radiation. Seeds stored in its vaults can remain viable for centuries under the right conditions; researchers have found that every 5-degree Celsius drop in storage temperature, combined with a 1-percent reduction in seed moisture, can double a seed’s viable lifespan. Kew scientists have used some of this material to help develop coffee plant varieties resistant to temperatures up to 6 degrees higher than current cultivated strains, which matters in the context of what is happening to highland coffee-growing regions across Africa and Central America.

Wakehurst is a separate site (in Haywards Heath, West Sussex, roughly an hour south of London) and requires a separate visit, but it is included if you hold an annual Kew membership.

The Gardens Themselves

Kew covers 132 hectares in the London Borough of Richmond upon Thames. It received UNESCO World Heritage status in 2003, and it is worth spending at least four to five hours here to get past the obvious highlights.

The Palm House is the most photographed structure: a Grade I-listed Victorian glasshouse built between 1844 and 1848, housing tropical plants including some of the oldest potted plants in the world. The central walkway at ground level is where most visitors stay; the upper gallery that runs around the perimeter at canopy level has better views and fewer people.

The Temperate House is the largest Victorian glasshouse in the world (4,880 square metres) and was fully restored in 2018 after a five-year project. It holds plants from every temperate zone, including a Chilean wine palm that is over 160 years old and too tall to be moved. The Princess of Wales Conservatory covers ten different climate zones within a single building, including zones for carnivorous plants and giant water lilies.

Kew Palace, a small red-brick building near the river, was home to King George III and his family during the years of his illness. It is the most personal royal residence in London and the least visited. In 2026, a major Henry Moore sculpture exhibition is running across the outdoor grounds, described as the largest presentation of Moore’s outdoor work ever mounted at Kew.

The Marianne North Gallery is easy to overlook and should not be. North was a Victorian botanical artist who spent 15 years travelling alone to paint plants in their natural habitats across Asia, Australia, Africa, and the Americas. The gallery holds 833 of her paintings covering every wall, floor to ceiling, in a sequence she designed herself. It is one of the most unusual rooms in any public institution in London.

Tickets and Getting There

Peak season tickets (February to October) are 20 pounds for a weekday online booking and 22 pounds at weekends. Off-peak (November to January) drops to 12 pounds on weekdays. From 25 June to 1 September 2026, prices are reduced further as part of a government tourism initiative. Children under 4 are free; children 4-16 are reduced rate. The gardens open at 10:00 daily; closing times range from 16:00 in winter to 20:00 on summer weekends. Online booking is strongly recommended, particularly for weekends.

From central London, take the District line (Richmond branch) to Kew Gardens station, which puts you 500 metres from the Victoria Gate entrance. The journey from Westminster is around 30 minutes; from Earl’s Court around 15 minutes. South Western Railway trains from London Waterloo to Kew Bridge station take about 30 minutes and deposit you at the north side of the gardens near Elizabeth Gate. By car, parking at Brentford Gate costs 10 pounds per day.

Eating

The Botanical Brasserie near Victoria Gate is the main full-service restaurant, with a menu that changes seasonally and skews toward the kind of produce-led cooking that suits a post-garden afternoon. The White Peaks Cafe near the Temperate House is better for a quick lunch. Both are pricier than equivalent food outside the gates. Picnics on the lawns are actively encouraged and, on a dry day, the better option: the grass areas around the Palm House and along the riverside walk are unusually pleasant.

For dinner, the Richmond riverfront (15 minutes’ walk from Kew Gardens station) has a range of restaurants from informal pizza to The Petersham Hotel, which has a restaurant with views over the Thames bend below Richmond Hill that has been one of the better kitchens in south-west London for decades.

Where to Stay

The Kew Gardens Hotel on Station Parade is directly opposite the tube station, has 20 rooms, a pub, and a restaurant. It is the most convenient option for a Kew-focused stay, with rooms typically running 120-180 pounds per night. The Petersham in Richmond is a classic Victorian pile on Richmond Hill with river views and a higher price point. Budget travellers will find better rates in Kew or Richmond than in central London while remaining well-connected by the District line.

The combination of Richmond Park (the largest urban park in London, a 20-minute walk from Kew) and the Thames riverside path north toward Hammersmith makes this part of London considerably more rewarding than most visitors from outside the city expect. The gardens are the reason to come; the area around them is the reason to stay an extra day.
