Three hours is the least that makes a Kew ticket worth buying, five to six hours covers everything most visitors actually want to see, and a full day is only for people who like plants for their own sake. The site is 132 hectares, so the thing that eats your time is walking between the glasshouses, not queueing at them.
Kew Gardens is a working botanic institution and a UNESCO World Heritage Site, not a park you stroll into. It charges admission, it closes earlier than you expect in winter, and the famous glasshouses shut two hours before the gardens do. Get those three facts into your plan and the visit works. Miss them and you will spend £25 to look at lawns.
Our full guide to Kew Gardens describes the Palm House, the Temperate House, the Treetop Walkway and the rest, and gives the current ticket prices. This page is about the clock: what fits into each block of time, which gate to walk in through, and when a shorter visit is the right call.

What three hours buys you
Three hours is enough for the four things most people come for, provided you walk them in the right order and do not stop for a long lunch. Start at Victoria Gate, which is the entrance closest to Kew Gardens station, and work south.
- Palm House (about 40 minutes). The tropical glasshouse with the rubber tree and the cocoa tree. Hot, humid and worth the discomfort.
- Princess of Wales Conservatory (about 30 minutes). Ten climate zones under one roof, from desert cacti to carnivorous plants and the giant waterlily.
- Temperate House (about 40 minutes). The larger of the two great Victorian glasshouses, holding around 1,200 species that cannot survive frost.
- The walk between them (about 45 minutes in total). This is the part people forget to budget for.
That leaves you a little over twenty minutes for a coffee and the walk back to the gate. It is a real visit, and if the weather is poor it is arguably the best three hours in London, because all of it is indoors.
What three hours does not include: the Great Pagoda, the Treetop Walkway, the Children's Garden, the Arboretum, the art galleries and any wandering at all. Accept that before you go rather than discovering it at 3.45pm.
What the fourth, fifth and sixth hour add
The extra hours are where Kew stops being a glasshouse trip and starts being a day out.
- The Great Pagoda needs its own timed slot, bought as an optional extra with your ticket, at the gate or at the Pagoda itself. It is at the far southern end of the gardens, so allow the climb plus a long walk each way.
- The Treetop Walkway puts you 18 metres up among the crowns of sweet chestnut, beech and oak. There are 118 steps and a lift. It can close in high wind, so check Kew's closures page on the day if it is the thing you came for.
- The Arboretum holds about 11,000 trees and is the reason to come in autumn. You cannot rush it; it is a landscape rather than an exhibit.
- The free guided walks, "Introduction to the Gardens", start at 11am and 1.30pm daily and are included in the ticket. If you have five hours and no plan, take the 11am one and build the rest of the day around what you liked.
- Henry Moore: Monumental Nature, an outdoor exhibition of Moore's sculpture placed across the gardens, runs to 31 January 2027 and needs no extra ticket.
Five o'clock is the deadline that matters
The glasshouses at Kew open 10am to 5pm all year, and the gardens around them close at a different time every few weeks. In September 2026 the gardens are open until 7pm, which means there are two full hours in the evening when you can walk the lawns but not enter a single glasshouse.
| Dates, 2026-27 | Gardens | Glasshouses | Usable glasshouse time if you arrive at opening |
|---|---|---|---|
| September 2026 | 10am to 7pm (last entry 6pm) | 10am to 5pm | 7 hours |
| 1 to 24 October 2026 | 10am to 6pm | 10am to 5pm | 7 hours |
| 25 October to 11 November 2026 | 10am to 4pm | 10am to 5pm | 6 hours, limited by the gardens closing |
| 12 November 2026 to 3 January 2027 | 10am to 3.15pm | 10am to 5pm | 5 hours 15 minutes |
An afternoon arrival in winter is barely a visit at all. From 12 November 2026 the gardens close at 3.15pm. Turn up at 1pm and you have two hours and fifteen minutes for a 132-hectare site. If you cannot get there for opening in the winter months, go on another day instead.
Which gate you start from changes the whole day
Kew has four public entrances and they are a long way apart. Picking the wrong one adds half an hour of walking before you have seen anything.
| Gate | Nearest arrival point | Start here if |
|---|---|---|
| Victoria Gate | Kew Gardens station, about 500 metres | You are arriving by Tube or Overground and want the Palm House first |
| Elizabeth Gate | Kew Bridge station, about 800 metres | You are coming on South Western Railway, or from Kew Green |
| Brentford Gate | Kew Gardens car park, TW9 3AF | You are driving; parking along Kew Road itself is prohibited |
| Lion Gate | Southern end of the gardens | The Great Pagoda is your priority - but see the warning below |
Lion Gate opens only at weekends from 2 November 2026 to 29 January 2027. If your plan was to arrive there on a Tuesday in December and walk straight to the Pagoda, it will not work, and the diversion to another gate is a long one.
One more detail that matters on the way home rather than the way there: the westbound platform at Kew Gardens station is not step-free. If you are continuing towards Richmond with a buggy or a suitcase, plan for stairs. Our guides to step-free travel across the network and accessible London cover the alternatives.
Kew with children, and how long they really last
Children aged 4 to 15 pay £2 online, which makes Kew one of the cheapest family attractions in London per hour. The realistic limit is not the ticket but attention. Two hours of glasshouses is a lot for a seven-year-old.
The Children's Garden is built for ages 2 to 12, covers an area the size of about 40 tennis courts, and has a four-metre canopy walk around a 200-year-old oak, bamboo tunnels, trampolines and hammocks. You do not need to book it, and adults may only go in with a child. Kew says it is quieter first thing in the morning and in the late afternoon, which is the opposite of when most families arrive.
Our suggested shape for a family day: glasshouses from 10am while everyone is fresh, lunch, then the Children's Garden for as long as it holds. That is about four and a half hours and nobody is miserable. The Treetop Walkway is good with older children but buggies have to be left at ground level. There is more in our guide to London with kids.
How long it takes if walking is difficult
Distance is the issue at Kew, not steps, and the gardens are set up for that. Wheelchairs are available to borrow at all public entry gates with no need to book; just ask when you arrive. Mobility scooters can also be borrowed, but they must be booked in advance, and Kew recommends at least two weeks' notice. They are collected from Brentford, Victoria and Elizabeth Gates.
Scooters are restricted in places, and the restrictions change how long things take. The Temperate House and the Alpine House take both wheelchairs and scooters. The Palm House takes wheelchairs but not scooters. The Princess of Wales Conservatory takes both, but its upper floor takes neither. Kew publishes an accessibility map that prioritises this information, and there are accessible toilets near all the main attractions, cafés and gates.
If you are planning around a scooter booking, allow more time than an able-bodied visitor would for the same list, because of the sections you have to route around. Five to six hours is a more honest figure than three.
Is half a day worth £25?
Our view: yes, if the weather is bad and you go straight to the glasshouses, and yes if you are interested in plants at all. No, if you have three hours, good weather and a general curiosity about London, because London has better free green space than almost any other capital, and Richmond Park is two stops away and costs nothing.
There is a way to sidestep the question entirely. Kew's "£10 Tuesdays" run to 29 December 2026 and cut the adult price from £25 to £10. A couple pays £20 rather than £50. If your dates are flexible at all, move the visit to a Tuesday; our page on seeing London on a budget lists other savings of the same kind.
A three-hour visit on a £10 Tuesday is better value than a full day at the peak price. Two adults pay £20 instead of £50, which changes the arithmetic completely: at that price, even the glasshouses alone are worth the trip out.
What to do with the rest of the day
Nobody should plan Kew plus another major attraction in the same day, but Kew plus a walk works well. The village of Kew and the riverside at Strand-on-the-Green are a short walk from Elizabeth Gate; our guide to Chiswick and Kew covers both and explains the District line problem. One stop further and you are in Richmond for dinner by the river.
If gardens are the point of your trip rather than a single afternoon, the Chelsea Physic Garden is far smaller and takes about two hours, Hampton Court Palace has the grandest historic gardens within the London boundary, and our page on what happened to the Hampton Court Flower Show explains where that July garden day has gone.
Kew is also a strong wet-weather plan, which our list of things to do in London on a rainy day covers, and it changes character completely in autumn and at Christmas. See autumn colour in London for the Arboretum in late October, cherry blossom in London for the spring alternative, and Christmas at Kew for the evening light trail, which is a separate ticket and a separate visit.
Frequently asked questions
How many hours should you set aside for Kew Gardens?
Three hours is the practical minimum and covers the Palm House, the Princess of Wales Conservatory and the Temperate House with the walking between them. Five to six hours adds the Pagoda, the Treetop Walkway and the Arboretum without rushing. A full day suits keen gardeners.
Can you see Kew Gardens in two hours?
You can see two glasshouses. You cannot see Kew. The site covers 132 hectares and most of the time goes on walking between attractions rather than inside them. If two hours is all you have, either move the visit to a "£10 Tuesday" or spend the time in a free London park instead.
What time do the glasshouses at Kew close?
All the glasshouses close at 5pm, regardless of when the gardens themselves close. In September 2026 the gardens stay open until 7pm, so the last two hours are outdoors only. Plan to be inside the Palm House and Temperate House by mid-afternoon.
Which gate should I use at Kew Gardens?
Victoria Gate if you arrive at Kew Gardens station, about 500 metres away. Elizabeth Gate if you come to Kew Bridge, about 800 metres. Brentford Gate if you drive. Lion Gate is nearest the Pagoda but opens only at weekends from 2 November 2026 to 29 January 2027.
How long does Kew take in winter?
Less than you want. From 12 November 2026 to 3 January 2027 the gardens open 10am to 3.15pm, which is just over five hours in total. Arrive at opening, do the glasshouses first, and treat anything outdoors as a bonus.
