Lamoureux Park Playground

The splash pad here gets absolutely packed on hot summer days, and honestly, it earns every bit of that crowd. Sitting right along the St. Lawrence, the views are genuinely hard to beat — parents tend to claim a bench early and just stay for hours. It works well for a pretty wide age range, from toddlers just figuring out the water to older kids running around. If you’re doing a family afternoon in Cornwall, this one’s worth the trip.
