Lammas lower playground and splash park (waterpark)

The splash park at Lammas Lower sits right on the edge of Chertsey, a proper lifesaver on those sticky summer days when the kids are climbing the walls. It's nothing fancy - just a good, functional water play area with jets, fountains, and that shallow paddling setup that keeps toddlers entertained for hours without drowning hazards. The playground runs alongside it, so you can park yourself on a bench while the little ones alternate between swings and splashing about.

Timing-wise, you're looking at a couple of hours maximum unless your kids are genuinely obsessed with water. Go mid-week if you can; weekends get rammed, especially during school holidays. Summer mornings before 11am are your sweet spot - the sun's not too fierce and it hasn't turned into a scrum. Admission appears to be free, which helps if you're camping at one of the nearby sites like Chertsey Caravan Park or the Camping and Caravanning Club spot, both within easy driving distance.

It's a decent add-on if you're basing yourself in the area - close enough to Chertsey town centre for an ice cream run, and near enough to the Thames that you could combine it with a riverside walk. Don't expect anything adventurous or challenging; this is straightforward family entertainment. Honestly, if your children are old enough for proper water slides or complex play equipment, they might find it a bit basic after the first half-hour. But for younger kids or a quick cool-off? Well worth the detour.
