The park office is located near the north entrance to the park, directly behind the interpretive center. Camping fees can be paid at the park office during the off-season (November through March) or when the campground host is off-duty during the on-season (April through October), during office hours. Missouri State Parks gift cards, as well as Discovery Program patches for completion of the Washington State Park Discovery Program, are sold at the park office. Those who complete the Missouri State Park Explorer Program or are participating in the Missouri State Park Camper Award may receive their verification at this location from park staff.
