It's fine
Like most Iowa state parks, no sewer or water hook ups at site. Not super level. Near red rock, but cannot see the lake from the campground, cannot access the bike trail directly from campground. Wooded area, no trails or anything special in the park. Showers flooded the bathroom and had to push the button every 30 seconds to keep the water going.
Around this area there are many Marion county campgrounds that have better sites and amenities.
