Birkenhead Park
The park Central Park was copied from: two lakes, a covered Swiss Bridge, a playground with a climbing boulder and acres of flat grass, all free. The visitor centre has the cafe and the toilets.
10 places in Wirral, Merseyside, 5 of which cost nothing. Everything below is within easy reach if you live locally.
The Wirral crams more variety into one peninsula than anywhere else this site covers. New Brighton alone has a beach, a marine lake and the driftwood Black Pearl pirate ship, with Bubbles World of Play and Eureka! Science + Discovery minutes away - Eureka's entry converts to an annual pass, which changes the maths for a second visit. Tam O'Shanter Urban Farm under Bidston Hill is free, does pigs, goats and alpacas, and the cafe's bacon butties are reason enough.
The Dee side is the quieter half. Wirral Country Park at Thurstaston, Britain's first country park, runs a clifftop path above a beach where children hunt fossils in the boulder clay, with Church Farm five minutes away and Ness Botanic Gardens further down the estuary. Birkenhead Park, West Kirby Marine Lake, the Wirral Transport Museum and the soap-baron streets of Port Sunlight fill whatever gaps remain. Days out on the Wirral with kids mostly cost parking money, and the hard part is picking a coast.

Beach, marine lake, Fort Perch Rock at the river mouth, and the driftwood Black Pearl pirate ship built from beach findings that children treat as the best playground on Merseyside. Chips on the front to finish.

A free community farm under Bidston Hill: pigs, goats, alpacas and hens, a woodland on the doorstep, and a café doing proper bacon butties. One of Merseyside's best zero-cost mornings.

A mile-long flat promenade loop around a giant saltwater lake on the Dee estuary, with dinghies and paddleboards for hire from the council-run watersports centre and a sandy beach alongside. Free unless you get on the water.

Britain's first country park: a clifftop path above the Dee, a beach for fossicking below, and a visitor centre with bird hides. Wild-feeling without being remote.

Billed as the UK's biggest soft play. A long drive for soft play, but it's the one that turns a rainy day into an actual event, and the seafront is right there.

A small, friendly Wirral farm park with animal handling most days, a maize maze in late summer, and Thurstaston Common and the beach five minutes away for a two-stop day.

The story of the village Lever built for his soap workers, with a preserved worker's cottage on the same ticket and £2 trails to pull children round the prettiest streets on Merseyside. A gentle history stop, not a rides day, and priced like it knows that.

A hands-on science centre built precisely for this age group - walk-through lungs and a supersize brain in the new Bodies gallery, inventions to test, and the ferry stop is literally outside. Entry converts to an annual pass, which changes the maths entirely.

University of Liverpool's gardens above the Dee estuary: family trails, a wildflower meadow, a good playground and views across to Wales. Quieter than the National Trust circuit and better value.
1 dated event coming up, 1 of them this weekend.
Walk through a pair of giant lungs, meet a supersize brain and follow the digestive system to its logical conclusion. New gallery, runs to December.
Not in Wirral, but close enough for a day out.

Free, indoors and better than it sounds: interactive science aimed at younger children, glassblowing demos, a picnic area and a small playground outside.

St Helens' biggest park. Play areas, open space and a walled garden, and it costs nothing.

A 20-metre white head rising out of a reclaimed colliery, with woodland trails around it. Genuinely strange and memorable for kids, and a short walk rather than a hike.

A green corridor of canal towpath and parkland running from St Helens down towards Warrington. Flat, traffic-free and ideal if the bikes or scooters are coming.

Family nature sessions running through August at two St Helens parks. Pitched at exactly this age group.

Funded holiday clubs with food included, ages 4 to 18, for families on benefits-related free school meals. Worth a look even if you assume you won't qualify.

Space World in Prescot, Sensory Hive in Whiston and Boomerang: the council-listed indoor options when it rains and everyone is climbing the walls.

Soft play with a full role-play village attached, which is the bit that holds a four-year-old's attention long after the frame stops being interesting.
