Excellent free place to stop over for a night or two. It doesn't really have a campground feel or setup, but rather it's a park that allows overnight camping for 7 nights.
Tents are ok but not allowed to stay on the grass during the week, because the sprinklers are on all night long (and will also spray your vehicle if you park along the grass). There aren't any designated or numbered camp spots, but it seems that each picnic bench and grill sort of counts as an individual spot. But I'd say if you have a small vehicle and all the "spots" are taken it would be fine to just squeeze in somewhere for the night.
No cell service down here. There are trash bins and a pit toilet. Nice river running through and a lot of people come here for the day to fish and picnic. There's also a little playground for kids.
Easy access for medium-ish RVs, not sure if I'd attempt to bring something huge down here. The park is a long road with a small turnaround area at the end but when we were there a big class A was blocking a lot of the turnaround area (because they didn't parallel park at the site and pulled in straight instead). Also a lot of low hanging branches scraped as we drove through, so something taller or bigger might have issues.
