How Long to Spend at the Natural History Museum

Published 21 September 2026 · By the Guide to London editorial team · Editor: Terje Moy

Two hours is the museum's own answer, and it is the right one. All three of its published self-guided routes are timed at 90 minutes to two hours. With children, add an hour for the queue, the breaks and the walk back to the station.

The Natural History Museum was the most-visited attraction in Britain in 2025, with 7,116,929 people through the doors. Spread across the open days that is around 19,700 visitors a day, which is why the time you spend here is decided as much by other people as by the galleries.

Our main guide to the Natural History Museum covers the entrances, the free ticket, the contents of each wing and this season's closures. This page answers a narrower question: how much of your day the building will actually take, and what you get for each hour of it.

Where the time actually goes

Break a typical visit into its parts and the pattern is clear. The queue outside takes between nothing and forty minutes. The bag search takes five. Hintze Hall takes fifteen, because everyone stops under the whale. The Dinosaurs gallery takes forty minutes, and you cannot shorten it much: the route runs in a single direction along a raised walkway, and there is no way back past the people ahead of you.

That is already an hour and a half before you have seen a volcano, a gemstone or a mammal. Two hours is not a modest plan; it is a realistic one that includes two of the museum's biggest draws and very little else.

The walk from South Kensington station adds about five minutes each way through the pedestrian tunnel, and the museum is long: it is a two-minute walk from Hintze Hall to the far end of the East Wing, and you will do that walk more than once.

The queue is the variable, not the galleries

Entry is free and nothing has to be booked, but the museum warns of queues to get in at weekends and during the school holidays, and says that members and ticket holders walk past them. A free timed ticket takes that uncertainty out of the day at no cost.

This matters more than any other timing decision on this page. On a rainy Saturday in the school holidays the difference between a booked slot and turning up is not five minutes; it can be most of an hour standing on Cromwell Road. Our page on London during the school holidays lists the weeks when this is worst.

One hour: Hintze Hall and one gallery

An hour covers the main hall, the whale skeleton, the balconies above it and exactly one other gallery. Choose that gallery before you go in, because choosing it at the information desk costs ten minutes you do not have.

If you are with children, make it Dinosaurs and accept that you will see nothing else. If you are not, make it the Vault or the Minerals gallery, both in the Central Building, both quiet and both close to the main hall. There is a free audio commentary for the main hall, recorded by Sir David Attenborough, played through a phone you hold yourself, so carry headphones rather than buying a pair at the desk.

What an hour does not allow is the East Wing. The Earth Hall escalator, Volcanoes and Earthquakes and Earth's Treasury are a separate expedition at the far end of the building, and starting them with twenty minutes left is how people end up being asked to leave.

Two hours: the museum's three routes, compared

The museum publishes three self-guided routes, each starting at a different entrance. They are free, they need no booking, and they are the most efficient way to use two hours here.

The choice of entrance is part of the timing, not a detail. Family favourites begins outside with Fern, the bronze Diplodocus, and goes on to the mastodon, the Dinosaurs gallery, the Mammals Hall and the fishes and reptiles. Exhibits with impact starts at the other end of the building with the Stegosaurus in the Earth Hall and the earthquake simulator, and works back towards Hintze Hall. Hidden treasures avoids both crowds entirely, starting in the Nature Discovery Garden and going through the spirit collection and the Images of Nature gallery.

If two of you want different things, splitting up and meeting in Hintze Hall at a fixed time is more efficient than compromising. The building is too large to wander through together without losing half an hour to negotiation.

Three hours with children, and the point at which it stops working

Three hours is the realistic upper limit for children under about eight, and only with a proper break in the middle. The galleries are warm, the museum has no air conditioning in the historic building, and the noise in Hintze Hall on a busy day is considerable.

Build the break into the plan rather than waiting for the meltdown. The gardens outside have a pond, an evolution timeline and space to run, and going out and coming back in costs nothing. Our round-up of museum and gallery cafés covers the alternative if the weather is against you, and our family guide to London and page on visiting London with a baby deal with the rest of the day.

Lifts are worth checking before you commit to a route with a pushchair: the museum keeps a live list of gallery closures and out-of-service lifts, and in September 2026 several in the Darwin Centre and the one in the Mammals Hall were out. Our page on moving around the city with a pushchair covers the journey there.

A full day only works if you leave and come back

The museum is open for seven hours and fifty minutes. Almost nobody should spend that long in it in one stretch. Given a whole day in South Kensington, the sensible shape is two hours here, an hour outside, then either the second half of this museum or the museum next door.

Going out is easy: entry is free, there is no re-entry check beyond the bag search, and South Kensington has cafés within five minutes in every direction. Kensington Gardens is about ten minutes north.

The last ninety minutes, from 16:20 to 17:50

The late afternoon is the museum's most underrated slot. Last entry is 17:30 and the building closes at 17:50, so arriving at 16:20 gives you ninety minutes in galleries that are emptying rather than filling. School groups have gone by mid-afternoon, and the families who arrived at 10:00 are leaving.

Dinosaurs, which grows its own queue inside the building in the middle of the day, is usually walkable at this hour. The trade-off is obvious: you get one gallery and the main hall, not a visit. Treat it as the second half of a day that started somewhere else.

What to cut first

If you are running short, cut in this order. First the shops, which are placed where you will walk through them anyway. Then the Images of Nature gallery and the Minerals gallery, which are lovely and which nobody has ever regretted saving for another trip. Then Human Evolution and the Lasting Impressions gallery in the East Wing, which are a long walk from everything else.

Keep Hintze Hall, keep Dinosaurs if you have children, and keep either Volcanoes and Earthquakes or the Earth Hall if you do not. Do not try to keep all three of the South Kensington museums in one day, whatever your itinerary says.

Timing it against the Science Museum next door

The Science Museum is five minutes away and says an average visit there lasts around two hours. Two two-hour museums plus lunch is a six-hour day, which is a lot, and the V&A across the road makes it eight. Our comparison of the Natural History Museum and the Science Museum sets out which to choose if you only want one.

Older children often prefer the Science Museum's paid Wonderlab to anything here, which changes the arithmetic; our page on museums that work for teenagers explains why. For other timing questions of this kind, see our guides to how long the British Museum takes, how long Kew Gardens takes and the choice between Tate Modern and Tate Britain. If the weather has sent you indoors, our list of free museums in London and our page on rainy days in London have the alternatives.

Frequently asked questions

How many hours is enough for the Natural History Museum?

Two hours is the right length for most visitors, which matches the museum's own self-guided routes. Families with young children should allow three hours including a break outside, and anyone with only one hour should plan to see Hintze Hall and a single gallery.

Can you do the Natural History Museum in an hour?

Yes, provided you decide in advance which single gallery you are seeing. One hour covers the security check, the main hall beneath the whale skeleton, the balcony above it, and either Dinosaurs or a quieter room such as the Vault.

What is the best time of day to visit the Natural History Museum?

Either the first thirty minutes after the doors open at 10:00, or any time after 16:00, once school groups and the morning families have gone. Midday is the worst, and that is also when Dinosaurs grows a queue of its own indoors.

Should I book a free ticket for the Natural History Museum?

You do not have to, because entry is free either way. It is still worth doing: a timed ticket guarantees admission and takes you past the queue outside, which at weekends and during school holidays can be the longest part of the whole visit.

How long does the Dinosaurs gallery take?

About forty minutes at a normal pace. Because the walkway runs in a single direction, you move at the speed of whoever is in front of you and cannot easily turn back. It clears quickest just after the doors open and again late in the afternoon.
