I stayed at the main site that google maps took me to. Three spots but the park is big there might be more sites around it. It is near skunk river I only stayed there for a night but where I was to get to the river you have to hike or bike to it. I’ve heard you can ride horses here. They have fire rings, picnic tables, and a bathroom that’s deep and composting. No sinks or showers. Bugs were wild at night but it is summer. No one disturbed us and it was free the best park of it all. Hoping to make it back there to go through the trails. I believe you can hike and camp too in the area.
$12 a night for primitive camping and you get nice warm showers by the main entrance and nice bathrooms by the main entrance. Stand-alone bathrooms throughout the park have the deep composting toilets that smell bad but whatever the ones up front are nice. Would recommend 10/10
