Hi
There is one park but it's in Milford not sure how far you are willing to go but it's called Keyes field and they have a little playarea for toddlers. Slide and they also have a sandbox you bring your own shovels and pails but it's great fun.
It's on Elm st in Milford. They have baseball fields, swimming pool but that's for Milford residents only but they have tennis court. It's fun tfor the kids.
If you have any more questions please email me at ____@____.com
I live in Wilton so I still have to drive to Milford but it's worth it my kids love it. I have a 17 month old girl and a 4 year old boy they love it there.
T.
