World Museum, Liverpool
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.

The 50m tank converts into 25m deep and 25m shallow via a moveable floor. Alongside it sits a 20m pool kept at 30 degrees, three degrees warmer than the big one, and that is the difference between a nice hour and a shivering child. Depths run 0.9m to 1.5m in the small pool, so a confident seven-year-old can stand in most of it.
The money is unusually good. Under-8s swim free, a junior is £2.30 and an adult £4.60, so a parent with two small children pays £4.60 all in. A family swim covering two adults and three children is £10. You need a free Lifestyles online account to book anything, but public and adult swim sessions are turn-up-and-go within the published hours.
Plan around the weekend hours, which are short: the centre runs 8am to 4pm on Saturday and Sunday, against 6.15am to 10pm on most weekdays (Wednesday opens at 9.30am and Friday closes at 9.30pm). Public swims move between pools, with a Sunday split between the 20m pool first thing and the shallow half of the big pool from late morning, so check the timetable on the centre page the morning you go.
What it costs: Swim: adult £4.60, junior £2.30, adult and senior concessions £2.30. Children under 8 swim free. Family swim £10.00 for two adults and three children, up to six people with extra charges per person. Prices published by Liverpool City Council Lifestyles. You need a free Lifestyles online account to book activities.
Worth knowing: Strict ratios: one adult per child under 4, one adult per two children aged 4 to 7.

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. The Maritime Museum and the International Slavery Museum next door are shut for essential maintenance ahead of a major redevelopment that National Museums Liverpool says is subject to funding, and no reopening date is published. The Albert Dock around them is still worth the walk, and the city's other national museums are 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.
