Theme Parks in East of England

5 activities

Seaside rides, character play or water courses: it depends on age

The five here split into three kinds of day. Adventure Island in Southend-on-Sea is the only traditional theme park among them, and the one Great Days Out UK lists in its directory of East of England theme parks alongside Pleasurewood Hills, Clacton Pier and Great Yarmouth Pleasure Beach. Entry is free and you pay for rides, and reviewers keep returning to two points: the evening wristband discount, and a seaside setting that stretches the day beyond the rides. Children under 120cm need an adult aged 14 or over with them on rides, which matters for anyone bringing a toddler and a teen together.

Nickelodeon Adventure Lakeside in West Thurrock is indoor character play rather than rides, pitched at Paw Patrol and SpongeBob fans of roughly three to ten. The space is large enough that parents mention losing sight of small children, and character meet-and-greet slots fill quickly, so pick up the schedule on arrival. Its dedicated birthday party rooms are the other draw.

The remaining three are water. Maldon Splash Park is free to enter and works for toddlers, with a pirate ship, zip wire and a flat river walk along the Blackwater estuary in the surrounding Promenade Park; sessions must be booked through a free online membership. Aqua Splash Inflatable Assault course at Sawbridgeworth and Aqua Parcs Stevenage are inflatable courses for six and up. Sawbridgeworth reviews praise the lifeguards but repeatedly mention bird mess on the inflatables, so inspect before your session. Stevenage runs small groups of around nine, which reviewers say means less waiting, and it suits confident swimmers only; teens rate it highly. Both have directions reviewers found unclear on arrival.

For any of the water options, book sessions online before you leave home, and at Stevenage complete the waiver in advance too.
