Nice small campground. One camping loop with nicely angled back-in's and three pull-thru's. We were the only RV there; even the camphost was gone for a few days. Very nice setting; large trees and grassy sites, but very wet since the park is set in the Missouri River bottomlands. Access road (Hwy 122) to the park is a little narrow, rough and twisty. Park access roads are very narrow, but all paved. Good hiking trails, with much Missouri Indian history emphasized. We were told by a local that mosquitoes are a real problem in the summer, but not while we were there in April. We camped here in a Fifth Wheel.
