You know the feeling. It is Saturday morning, the rain is hammering the windows, and two small people are already bouncing off the walls. The park is out. The garden is a mud bath. You need a plan.
Good news: London is actually brilliant on a rainy day when you have kids, if you know where to go. I have tested this itinerary with my own under-5s on more grey Saturdays than I can count, and it works. Here is a full day, morning to evening, that will keep everyone happy (including the grown-ups).
Do not rush. Rainy Saturdays are for slow mornings. Let the kids watch something while you drink a full cup of coffee. The goal is to leave the house by 10, not before. Pack a bag: spare clothes, snacks, a water bottle, and a rain cover for the buggy if you are taking one.
Head to one of London's big free museums. My top three for rainy days with small children:
The Young V&A in Bethnal Green is the gold standard. Three fully hands-on galleries designed for children under 12. Toddlers can build, dress up, and play for hours. It is free, indoors, and never feels as crowded as the South Kensington museums.
The Science Museum is another winner, especially the Garden gallery for 3-6 year olds (book a timed slot online). Water play, construction, and cause-and-effect experiments — they will not want to leave.
The Natural History Museum if your kids are in a dinosaur phase. Head straight for the dinosaur gallery, then up to the mammals room where the blue whale hangs overhead. Aim to leave by noon before the afternoon crowds arrive.
You have a few options here. If you are near South Kensington, the Franco Manca on Old Brompton Road does sourdough pizza that kids demolish. Near Bethnal Green? E Pellicci is a legendary Italian cafe with generous portions and a warm welcome for families.
Alternatively, do what we often do: grab a sandwich and eat it in the museum cafe. It is not glamorous, but it is dry and nobody judges you for crumbs on the floor.
After a morning of "look with your eyes not your hands," your kids need to move. This is the afternoon for physical activity.
Soft play is the obvious rainy-day choice. Gambado in Chelsea has a brilliant under-5s area and a cafe where parents can actually sit down with a decent coffee. Flip Out in Shepherd's Bush is more structured — kids try out different jobs (firefighter, dentist, pilot) in a mini city. It is paid but absorbing — easily two hours of entertainment.
Indoor swimming is another great option if your kids are water-confident. Many local council pools run open family swim sessions on Saturday afternoons. The pools at the Britannia Leisure Centre in Hackney and the Latchmere in Battersea are both family-friendly with gentle warm pools.
A big bookshop is the sleeper hit for rainy afternoons. The children's section at Daunt Books on Marylebone High Street, or the Waterstones on Piccadilly (the largest bookshop in Europe — six floors) all have dedicated kids' areas where they can sit and read. Free, warm, and oddly calming.
This is the tricky hour. Kids are getting tired. You are getting tired. But it is too early for dinner and bedtime is still three hours away. Two options:
Head home for quiet time. No shame in this. Put on a film, make tea, decompress.
Find a family-friendly cafe. If you are still out, Gail's Bakery (multiple locations) has high chairs, decent changing facilities, and good cakes. Barbie Green at London Wall Place in the Barbican area is another family-friendly option with a relaxed atmosphere where kids can unwind while you caffeinate.
If you still have energy for one more outing, an early dinner at a family-friendly restaurant is a lovely way to end the day. The key is going early — 5:30pm is perfect. The restaurant is empty, the staff are happy to see you, and your kids can be in pyjamas by 7.
Honest Burgers has a good kids' menu at most locations (check their website for current offers). Wahaca is great for small plates that toddlers can share. Pizza Pilgrims has colouring sheets and a relaxed atmosphere. Or go classic with Giraffe — one of the few chains that genuinely caters to families with a proper kids' menu, crayons, and changing facilities.
The Tube is your friend on a rainy day. Buggies are free on TfL, and most modern stations have step-free access (check the TfL app). If you are driving, the Science Museum car park is expensive but dry — expect to pay around 12 pounds for 3 hours.
