London has 151 activities that work perfectly on a rainy day — and given the climate, most Londoners have already figured this out. The city's free museums alone could keep a family busy for a week indoors. Here's what's actually worth doing when the weather turns.
Free Rainy Day Options
Start here. These are free and genuinely worth your time.
Natural History Museum — Free. 2–4 hours easily. The dinosaur hall, the blue whale, the earthquake simulator. Arrive early on weekends because everyone else has the same idea on a rainy Saturday.
Science Museum — Free. 2–4 hours for curious kids. Space exploration, medicine, engineering — six floors of it. Skip the paid IMAX and Wonderlab if you want a completely free day.
The National Gallery — Free. Pick up a free family trail from the desk. Works better for kids aged 6+ who can handle 45–60 minutes of focused looking.
Horniman Museum and Gardens — Free (aquarium extra). The walrus alone makes it worth the trip. About 2 hours for a family with young children.
London Museum Docklands — Free entry. The historic warehouse building is part of the experience. Budget USD 20–35 for the cafe if you want lunch.
Hone Books Galore — Free to browse. A children's bookshop where staff know their stock. Great for 30–60 minutes of rainy afternoon browsing.
Children's Bookshop London — Free to browse. Staff recommendations mean you won't waste money on books your child isn't ready for.
Moon Lane Books — Free to browse. Check the calendar for storytime events, often free or low-cost.
Art Classes and Creative Activities
All of these are fully indoor and work great as rainy-day bookings.
KidsArt! — USD 40–80 for two children. Multiple London locations. Children work with real art materials in sessions that are structured enough to give direction but open enough for genuine creativity. Kids leave with something they made themselves. Also available at KidsArt!, KidsArt!, and KidsArt! locations.

Bigger Splurges Worth It on a Rainy Day
Warner Bros. Studio Tour London — USD 160–200. Fully indoor and one of the best rainy-day splurges in the country. You need 3–4 hours minimum. Book well in advance — dates sell out months ahead. Bring food or eat before you arrive; the Studio cafe is expensive.

Practical Rainy Day Planning Tips
- Book art classes and activity sessions in advance, especially for school holidays. Drop-in availability on rainy Saturdays fills fast.
- Start with a free museum if you haven't planned ahead. The Natural History Museum and Science Museum can absorb most of a day and cost nothing.
- Covered taxi and car tours are underrated rainy-day options. You see everything, stay dry, and the kids think riding in a black cab is genuinely exciting.
- Bring snacks for museum visits. Museum cafes work out far more expensive than food you bring from outside — especially for families with multiple children.
- Warner Bros. Studio Tour and the Crystal Maze both need advance booking regardless of weather. Don't count on walk-up availability.
