Lancaster, Lancashire

Lancaster Castle is seen by guided tour only, and the castle is upfront that most of its history is crime, punishment and the enforcement of the law. The tour mentions physical punishment and hanging, and ten people convicted of witchcraft at the Summer Assize here went to the gallows on the moors above town. Some children will love it. Know yours.
Tickets are £9 for adults and £7 for children, with under 5s free and a £25 family ticket. You cannot book: tickets are sold on the day at the castle, first come first served. Tours take 60 to 75 minutes. At weekends and in school holidays they leave every half hour from 10 to 12 and 1.15 to 3.45, and less often on term-time weekdays.
The courtyards are free to wander without a ticket, and the Police Museum opens free on Thursdays and Fridays, which is a decent taster if the tour times do not line up. The Judges' Lodgings is at the bottom of the hill for a gentler hour afterwards.
What it costs: Adults £9, children 17 and under £7, 4 and under free. Family ticket £25 (two adults and two children, one adult and three children, or four children one of whom is over 16). Tours cannot be pre-booked; tickets are sold on site on the day, first come first served. The courtyards, and the Police Museum on Thursdays and Fridays, are free without a tour.
Worth knowing: Guided tour covers punishment and hanging. Not suitable for pushchairs or wheelchairs.

The Ashton Memorial dome you can see from the M6, with views across Morecambe Bay, a butterfly house, mini beasts and a good playground below it. Lancaster's best free afternoon.

Lancaster's council leisure centre doing triple duty: Energy soft play, XHeight climbing walls and a 33m pool with a waterslide and inflatable sessions. Cheaper than the private soft play chains, and everything is under one roof for a wet day.

Turner painted this view, which is worth nothing to a seven year old but does explain the crowds. A picnic site on the horseshoe bend of the Lune with tables, toilets and easy riverside walking.

Adults go in free and you only pay for the children who actually play. Giggles takes birth to ten in Lancaster Leisure Park, with the frames split by size so the crawlers are not flattened.

Forty-six acres north of the Lune with an accessible play area for under twelves, outdoor gym kit and five football pitches. Free parking, and a free junior parkrun every Sunday morning.

A pretend village for under 8s on the Lune Business Park: fire station, vets, supermarket, ice cream parlour and seven more wooden play shops. Booked sessions, calm by design, and very little climbing.
