Five floors, free, and it covers three things small children reliably love: giant dinosaurs, an aquarium and a space gallery. The best wet-weather day within half an hour.
Liverpool, Merseyside

Only Liverpool would build its soft play around a twenty-foot yellow submarine, and it works: the sub sits at the heart of the big frame with a helter skelter, spinning poles, an astra slide and biff-bash bags around it, a separate frame for the under-fours, plus an indoor football pitch and an arcade for the change in your pocket.
It is the useful kind of institution: open 9.30am to 6pm every day of the week, walk-in rather than pre-booked, with off-peak entry from £5.45 and babies at £1.95. On the waterfront side of town at Brunswick Business Park, it slots neatly before or after a free morning at the Museum of Liverpool up the road.

Five floors, free, and it covers three things small children reliably love: giant dinosaurs, an aquarium and a space gallery. The best wet-weather day within half an hour.

A Tudor hall with woodland walks, a maze and a natural play area in the grounds. Free if you have National Trust membership, and the indoor house is a good rain fallback.

The city's story with an overhead railway carriage to climb aboard and Little Liverpool, a dedicated hands-on gallery for under-6s. Free, on the waterfront, and the window views are half the fun.

Closed until 2028. The Maritime and International Slavery Museums shut in early 2025 for a full redevelopment. The Albert Dock around them is still worth the walk, and the city's other national museums remain free and open.

The famous ferry across the Mersey run as a 50-minute sightseeing loop with commentary, and the honest truth is kids love the boat more than any museum. Hop off at Seacombe for Eureka! next door.

South Liverpool's favourite park: lake, playground, ancient trees and the Storybarn, The Reader's hands-on storytelling space in the old coach house. The neolithic Calder Stones are older than Stonehenge, which is a good fact to deploy.
