Natural History Museum
Walk through the main doors and the first thing you see is a blue whale skeleton diving toward you from the ceiling of a hall that looks like a cathedral. That moment alone justifies the visit, and it is free. The Natural History Museum in South Kensington is a free, family-heavy museum stuffed with dinosaurs, gems, a model T-Rex that roars, and the kind of Victorian architecture that makes the building itself a specimen. The honest trade-off is the crowds: on weekends and in school holidays it can feel like a railway station, with real queues outside the Cromwell Road doors. Book a free timed slot, come early, and it is one of the best days out in London for nothing.

A free, genuinely great museum in a spectacular Victorian building, with the whale and the dinosaurs earning the hype. The only real downside is the crowds, which a timed slot and an early start mostly fix.
Worth it for
- Families with dinosaur-obsessed kids looking for a free day out indoors
- People who like grand architecture as much as the exhibits
You can skip if
- You can only go on a busy weekend afternoon and crowds ruin museums for you
- You want quiet, contemplative galleries; this one runs loud and packed
Tickets & tours for Natural History Museum
Which ticket should you buy?
Hintze Hall and Hope the whale
The central hall, Hintze Hall, is the showpiece. Suspended overhead is Hope, a real blue whale skeleton more than 25 metres long, posed mid-dive. She replaced Dippy the Diplodocus cast in 2017, and while plenty of people still miss Dippy, the whale is a stronger statement: a real animal, the largest that has ever lived, hung in a hall built to look like a temple.
It is also the most photographed spot in the building, so the floor below the whale is usually thick with people lining up the same shot. Climb the stairs to the upper landings for a clearer view and a look at the carved monkeys and architectural details Alfred Waterhouse worked into the terracotta. The hall is free and you do not need to do anything special to see it; it is the first room past the entrance.
Dinosaurs, and the rest of the galleries
The Dinosaur gallery is the one kids drag you to, ending with an animatronic T-Rex that moves and roars in a darkened room. It is also the most congested part of the museum, a single one-way route that backs up badly at peak times, so do it first thing or late in the day rather than midday.
Beyond the dinosaurs there is a lot: the mammals hall with its own life-size blue whale model, the Earth galleries you enter through a giant globe, an earthquake simulator, and the Vault of rare gems and meteorites. The Wildlife Photographer of the Year exhibition runs here too, and that one is ticketed. You will not see it all in a day, so pick two or three zones rather than trying to march through everything.
Free entry and the timed-ticket catch
General admission is free, but the museum strongly recommends booking a free timed-entry slot online, and at busy times it effectively becomes necessary. Turn up at the weekend without one and you may stand in a long line on Cromwell Road or be turned toward a later slot. The booking takes two minutes and costs nothing, so there is no reason to skip it.
Special exhibitions (like Wildlife Photographer of the Year) and seasonal events are separately ticketed and do cost money. Everything else, the permanent galleries, is free. Walk-ins are sometimes possible on quiet weekday mornings, but a booked slot is the safe play.
Beating the queue and getting in
There is more than one entrance, and that is the single most useful thing to know. The grand Cromwell Road entrance has the longest lines; the Exhibition Road entrance (shared with the Science Museum on that side) is often quieter and friendlier for prams and wheelchairs. There is also direct access from the South Kensington tube via a pedestrian subway, which spares you the rain.
Come at opening on a weekday and the difference is night and day. School holidays and rainy weekends are the crunch periods. Bags get checked on the way in, so travel light, and note that there is no large cloakroom for suitcases, which catches out people arriving straight from the train.
Natural History Museum: FAQs
Yes, general admission to the permanent galleries is free. The museum recommends booking a free timed-entry ticket online. Special exhibitions are separately ticketed.
You should. Entry is free but a timed slot is strongly advised, and at busy times it is close to essential to avoid long queues. Booking online takes a couple of minutes and costs nothing.
No. The Diplodocus cast that used to stand in the main hall was replaced in 2017 by Hope, a real blue whale skeleton. Dippy has toured elsewhere; the whale is now the centrepiece.
Come at opening on a weekday, book a timed slot, and try the Exhibition Road entrance, which is usually quieter than the main Cromwell Road doors. You can also enter via a subway from South Kensington tube.
Two to three hours covers the highlights (the whale, dinosaurs, and one or two other zones). A thorough visit with young kids can easily fill most of a day.
Very. The dinosaurs, the animatronic T-Rex, and the big animal models are a hit, though the dinosaur route gets crowded. There are baby-change facilities and family trails, but no large left-luggage.
