Catalyst Science Centre
Hands-on science galleries and a glass rooftop observatory over the Mersey. Small, cheap, indoors and close.
Widnes, Cheshire

Crazy Club sits inside Superbowl UK on The Hive leisure park off Earle Road. There are two frames: a bigger one for 4 to 12s with a giant slide, aerial gliders and a racing track, and a smaller toddler frame with a slide of its own, kept behind magnetically locked gates.
Standard prices are not published online, so check at booking. The term-time toddler clubs run for up to two hours and the breakfast and lunch ones include free food, which is the offer worth planning a weekday around. Children's meals are cooked to order, from pizza to hot dogs and chips.
Its real use is the mixed-age afternoon. Ten-pin bowling, a SEGA arcade and pool tables are in the same building, so an older child can bowl while a toddler finishes on the frame, and nobody has to get back in the car.
What it costs: Prices are not shown on the website. Term-time toddler clubs run up to two hours; the Wednesday breakfast club includes a free toddler waffle or toast and the Monday to Thursday lunch club a free cold lunch box.
Worth knowing: Main frame 4 to 12; separate toddler frame.

Hands-on science galleries and a glass rooftop observatory over the Mersey. Small, cheap, indoors and close.

Widnes's flagship park with a summer splash pad, big playgrounds, a skate park for older ones and a bandstand cafe. The local free default, minutes from Catalyst.

A man-made island between the Sankey Canal and the Mersey, reclaimed from the chemical industry into flat riverside parkland with big skies and boats to watch. Free parking, next door to Catalyst, and yes, it is where the Stone Roses played in 1990.

Salt marsh, then a rubbish tip for thirty years, now a nature reserve on the Mersey at Halebank. Wildflower meadows, surfaced riverside paths that take a pushchair, and a waterfront cafe that opened in 2026.

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.
