Public Swim: Hamilton Community Pool
The activity pool in the water play pool that includes a play structure, water slide and sprayers the for the little ones. There is a larger pool for swimming, but hours are different for drop-in swimming. See their calendar here.
You'll also find a large grassy area on the hill behind the pool that's perfect for spreading out your beach towels and picnic blankets. There are also plenty of picnic tables, some with charcoal BBQ grills, so bring your lunch and hang out for the whole day if you want. There's another grassy area on the other side of the pool with some picnic tables and large shade structures (spots in the shade here get claimed pretty quickly, so get here early if you want to stake out a shady spot).
