Chester Zoo
Excellent, but it is a lot of walking. Reviews rate 5 to 10 as the ideal age and still recommend a pushchair at four. Climbing frames, water play and sand pits break up the distance.
Grosvenor Museum
Chester, Cheshire
Chester's Roman story with the real evidence: tombstones from the fortress walls, a hands-on natural history gallery and a walk-through period house at the back.
Free, central and the right size for a morning. Combine with the city walls circuit and a river boat from the Groves.

The Ice Cream Farm
Free to get in, with a giant sand and water quarry, play areas and the ice cream counter that funds it all. Some indoor attractions charge per go; the outdoor bulk of it costs nothing but the cones.
The Crocky Trail
A mile of muddy obstacles, wobbly bridges and enormous slides through a Cheshire valley. Children come off it filthy, soaked and asking to go round again. This is the point; dress accordingly.
Beeston Castle
A ruined castle on a crag with views from the Pennines to the Welsh mountains, a reconstructed Bronze Age roundhouse and woodland paths below the walls. Castles do not need roofs to work for this age group.
Grosvenor Park & Miniature Railway
Chester's Victorian park above the river, with a miniature railway looping the lawns, a good playground and open-air theatre in summer. Pair with a boat trip from the Groves below.
Flip Out Chester
A big warehouse of trampolines, drop slides, laser tag and e-karts on the business park before Chester. Loud, sweaty and reliably popular - the off-peak slots are the value play.
