The Natural History Museum in South Kensington is one of London's most-visited attractions, and while most people queue for the dinosaurs gallery and the blue whale in Hintze Hall, there's a quieter, stranger offering behind the scenes: a T. rex-themed suite that lets guests stay overnight in the museum itself.

The suite is pitched as a once-in-a-lifetime sleepover for dinosaur fans. Instead of leaving with the crowds at closing time, guests get to settle in among the exhibits — think a bedroom kitted out with dinosaur details and the surreal experience of wandering one of the world's great natural history collections after the doors have shut. It's the kind of experience the museum has toyed with before through its adults-only 'Dino Snores' sleepovers, where visitors unroll sleeping bags beneath the galleries and enjoy late-night talks, comedy and food.

Even if an overnight stay isn't on the cards, the museum itself justifies the trip. Entry to the permanent collections is free, and highlights include the animatronic Tyrannosaurus rex, the Earthquake simulator, the human evolution gallery and the grand central hall presided over by the blue whale skeleton suspended from the ceiling. The building, opened in 1881 as part of the British Museum's offshoot, is a Victorian landmark in its own right, with the terracotta facade on Cromwell Road decorated with carvings of extinct and living species.

Practicalities matter here: free tickets book out fast, especially for school holidays and weekends, so reserve a timed slot online well ahead. The nearest Underground stations are South Kensington (a short tunnelled walk, handy in the rain) and Gloucester Road. Between visits, you're steps from the V&A and the Science Museum, making South Kensington an easy full-day itinerary.

Who's it for? Families with dinosaur-obsessed kids, obviously — but also anyone who fancies a grown-up night in a museum, which is rarer than you'd think in a city full of attractions. Whether via the suite, a sleepover event or just an early-morning weekday slot before the crowds, the Natural History Museum rewards going beyond the standard shuffle past the T. rex. Check the museum's website for the latest on overnight experiences and event dates, since these pop up and sell out seasonally.
