We've stayed here many times and keep coming back. Sites are always clean and hosts we've interacted with were always helpful and friendly. The Dairy Creek West loop has more shaded and privacy for most of the sites if thats what you are seeking, while the East loop is more open and affords a more social experience for those who like the chance to interact with their neighbors a bit more.
Aside from the sites, the park has many hiking trails of varying length, access to the Banks-Vernonia State Trail, several disc golf courses, cabins, a horse camp, a day use picnic/event area and a hike-in camp area.
Local astronomy groups often host star gazing events when the night sky is clear for various meteor showers or other astronomical events of interest.
