Ainsdale Beach
The one Sefton beach with RNLI lifeguards, on duty daily from late March to mid September, and the one where you can still drive onto the sand. Blue Flag, and backed by the Ainsdale dunes.
North West England
Splash pads, lakes, beaches, aquariums and pools. Bring a towel and a change of clothes.
A coastline the rest of the country tends to forget about, plus the indoor options for when the actual sea is out of the question.
Crosby Beach has Antony Gormley's hundred iron men standing out in the tide and costs nothing but the car park. New Brighton and the marine lake at West Kirby are both free and both better than their reputations suggest. Sandcastle at Blackpool is the indoor waterpark, warm all year, which counts for a lot here. Sea Life at Blackpool and Blue Planet at Ellesmere Port are the wet-day fallbacks. Fell Foot on Windermere is National Trust and one of the few places a child can get properly into a lake with a jetty and a cafe behind them. Check the tide before Crosby: the statues are only interesting when they are half submerged, and the sand out towards them is softer than it looks.

The one Sefton beach with RNLI lifeguards, on duty daily from late March to mid September, and the one where you can still drive onto the sand. Blue Flag, and backed by the Ainsdale dunes.

Seven miles of sand with the famous stretch between the piers: donkeys, deckchairs, and RNLI lifeguards all summer. Free, obviously, and still the best-value thing in town.

A hundred cast-iron men stare out to sea along two miles of sand - Antony Gormley's Another Place, and the strangest, most memorable free afternoon on this coast. Sand, statues, ships from the port gliding past.

A National Trust lakeshore park at Windermere's quiet southern tip: grassy banks straight into the water, paddling, boat hire and an adventure playground. The easiest safe lake-swim spot for families.

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.

Blackpool's seaside without Blackpool's volume: a huge flat beach, a Victorian pier with arcades, donkeys in summer and a paddling pool by the bandstand. The cheap day out on the Fylde coast.

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.

A Victorian lift that hoists whole canal boats fifty feet in the air, and you can ride it. Genuinely impressive to a small child, with a visitor centre and café on site.

One pool, a gym and a library on Longshaw Street, ten minutes from Warrington town centre. Nobody pretends there is a flume, but a child swims for £3.40, the same rate as the big LiveWire hubs.

There is a flume, and it is the only pool in this part of Sefton with one. Alongside it, a 25 metre main pool with a moveable floor, so the depth changes to suit the session.

It comes down to the slide. Two pools, one of them a warmer training pool, and a water slide, five minutes' walk from the Chester city walls. The wet weather backup for a day in the city.

The small pool runs at 30 degrees, which decides whether a three year old lasts forty minutes or eight. Two pools, a water slide and a jacuzzi, inside the Memorial Court in the middle of town.

Half an hour on the Dee from The Groves, past Grosvenor Park and along the Meadows, for £4.50 a child and free under 5s. Exactly as long as a small child finds a boat interesting.

Two pools a hundred yards from the beach, the smaller one shallow enough for a child who is still learning. On Tuesdays the main pool gets Atlantis Splash, a full length inflatable obstacle course.

Southport's indoor waterpark on the seafront: flumes, a wave machine, a lazy river and a proper toddler splash zone, all at 29 degrees. Open weekends year-round and daily in the Sefton holidays.

Ellesmere Port's biggest leisure centre: two pools, a cafe, parking on site, and a day that runs from half six in the morning until ten at night on weekdays. Under-threes swim for £2.

The flumes and the wave machine are gone for good. What is left is Birkenhead's main council pool, 25 metres and kept at 28 degrees, plus a soft play area over three floors for nought to sixes.

Formby kept the separate learner pool that most places quietly dropped: 12.5 metres, stepped access, a shallow end of 0.65 metres, which is the depth at which a two year old can stand up.

No flume, no wave machine. Two pools in a building on the west side of Warrington that also holds a library, tennis courts and 3G pitches. It does have pool hoists and a dedicated accessible swim session, which is rarer than it should be.

Pool, teaching pool, soft play, gym, sauna and a cafe in one building on Moor Lane, which means a swim and an hour of soft play without moving the car. One of the better wet weather answers in Halton.

A small, well-done aquarium at the quiet end of Windermere with an underwater tunnel walk beneath the lake's own fish, plus otters and rays. Pairs naturally with the steam railway next door.

Liverpool put its serious pool at Wavertree Sports Park: an eight lane 50m tank, and alongside it a 20m pool kept at 30 degrees, which is the one you actually want with small children. Under-8s swim free.

A 25 metre five lane pool and a 12.5 metre learner pool in Maghull, with a changing village of family cubicles instead of a shared bench and a fight. The library is in the same building, so a swim and a book run is one stop.

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.

Warrington's biggest LiveWire hub, with two pools under one roof. The one that matters is the small teaching pool, shallow enough for a three year old to stand up in. There is a library and a Subway on site.

Knowsley's flagship leisure centre on Longview Drive, open 6am to 10pm, with public swimming, parent and toddler sessions and lane swimming. Under-5s swim free, and under-8s must be in the water with a parent.

The Wirral pool that stayed open while others went in and out of maintenance closures through 2026. Pool, sports hall and a cafe on Grange Road, five minutes from the marine lake.

Sharks over a moving walkway tunnel, all under cover. A dependable answer to a washout forecast that still feels like a proper day out.

Huge sand dunes, a proper beach and red squirrels in the pinewoods behind it. The dunes alone will occupy them for an hour. Free entry if you have National Trust membership.

A charity with a whole dock basin at Queens Dock to play with. Children can kayak, paddleboard, take out a pedalo or throw themselves round an inflatable aquapark, in the middle of the city, with lifeguards on duty.

The UK's biggest indoor waterpark, kept at tropical temperature: proper toddler pools and mini slides at one end, big flumes at the other. Rainy-day Blackpool solved.

A solid seafront aquarium with an ocean tunnel and rockpool sessions - the reliable wet-weather hour when the beach plan falls apart.

Ocean tunnel, rays, seahorses and rockpool touch sessions, sized for smaller legs - you can do the whole thing in a morning and pair it with Legoland next door.

A giant inflatable obstacle course floating on a Cheshire lake: 50 minutes of climbing, sliding and falling in. Brilliant for confident swimmers aged 6 and up, no use at all for anyone smaller.

England's biggest lake from the deck of a proper boat, with red, yellow and green routes so you can pick a 45-minute hop or a full lake cruise. Combo tickets pair it with the aquarium or the steam railway.

Sefton's watersports centre on Crosby Marine Lake, with pay and play paddle sessions in season and the Gormley iron men on the beach over the road. More of a booked-session place than a turn-up attraction, so plan before you drive.
