Working steam engines, the story of Cottonopolis, and hands-on galleries in the world's oldest surviving passenger railway station. Free, and the live demonstrations are the bit kids actually remember.
Manchester, Greater Manchester

The nineties TV show rebuilt for real in a studio on Lower Byrom Street: four themed zones, around 75 minutes of physical, mental, skill and mystery challenges, and the crystal dome finale. Nobody spectates. The adults are in the games alongside the kids, which turns out to be most of the fun.
The rules matter here. Minimum age is 9, no exceptions, and any team with under-18s needs one paying, playing adult per team, so this is not a drop-off. Book a timed slot online, arrive 15 minutes early and allow about two hours on site. Standard tickets run around £44 each, with family tickets shaving about 10% off.
For a 9 to 11-year-old who takes puzzles seriously this is the good stuff: real locks, real crawl spaces, real time pressure. Just make sure everyone in the party clears the age bar before you mention it at home.
Worth knowing: Minimum age 9; teams with under-18s need a paying, playing adult.

Working steam engines, the story of Cottonopolis, and hands-on galleries in the world's oldest surviving passenger railway station. Free, and the live demonstrations are the bit kids actually remember.

A T. rex skeleton cast, live frogs in the vivarium, Egyptian mummies and a genuinely good natural history floor. Free, university-run, and less overwhelming than the big London equivalents.

Shirts, trophies and match footage across six floors, with penalty shootout and skills games that football-mad kids refuse to leave. If yours do not care about football, skip it - it is exactly what it says.

Watch jets take off close enough to feel them, with Concorde parked by the fence. Free in, pay for parking, and there is a play area and cafe for the wait between planes.

One of the biggest municipal parks in Europe: a free animal centre, boating lake, adventure playgrounds and an actual vintage tram running on summer days. You will not do all of it in one visit.

A big south Manchester park with a proper community farm - pigs, goats, horses - a Tudor hall, and enough playground to earn the trip on its own. All free.
