This is not a park we would have easily stumbled upon, but I'm glad we discovered it!
It seems very new. It is well-kept with a great bathroom facility, which was open when we were there. The playground is bedded with shredded tire, so you may want to avoid wearing light-colored clothing.
I'm guessing the main attraction at this park is soccer games, based on the many fields at the park. There are multiple covered picnic areas throughout the park. Supposedly you can also camp here; we didn't see any camping area, though, admittedly, we were not here long.
The park is right on the Wild Goose Trail as well.
