Dry Fork Campground is a free campground geared toward equestrians. It is a loop with multiple sites, picnic tables, vault toilet, fire rings, hitching posts, and even water! Wooded area. Fairly rural but there were a few other campers. It's a good option if you're traveling along I-70, which isn't far to the north. Some cell service. Room for one or two vehicles. Recommended.

This is a parking area for trucks to spend the night along I-70 in Missouri. A lot of trucks, and not a designated camping area by any means, but if you're traveling across the country and need some shut-eye for the night, it is a decent place to pop the camper. Good cell service. Small restroom. Give the trucks their space.
