Grimes is built for young families, so a free morning with the kids is easy to fill. Here is a go-to list of what actually works, all in or right by town.
The quick list
Start with the Waterworks splash pad on a hot day, play a free round at Glenstone MultiGolf, hit library story time, and finish with a scoop at The Outside Scoop.
The go-to list
Kid-friendly in Grimes
Waterworks Park splash pad (100 N James St) - free, with playgrounds alongside, in summer.
