Went up this last weekend to camp at the State park at Dardanelle. Found out they only take 2 night reservations on the weekend. I only wanted to stay for 1 night. They informed me of another state park campground on the Dardanelle side that is first come first serve. they also take single night campers. It is off Hwy 22. I took 7 south from 40 and ran into 22. It is a small but very nice campground with a great boat launch. $19 a night with electric and water. It is by the Lion's Den Golf Course.
