Mark Twain National Forest is the dominant land manager here

A lot of the public land in Oregon County is part of Mark Twain National Forest. The U.S. Forest Service runs this land. National forest land has its own rules. These rules cover dispersed camping (camping outside of set campgrounds), driving off-road, campfires, and hunting. They are not the same as the rules for state conservation areas or private land. Some parts of the forest have even stricter rules. Two of these are the Eleven Point Wild and Scenic River and the Irish Wilderness. So before you camp, hunt, ride, or cut firewood, find out which piece of land you are on. Then follow that area’s current rules. A general forest rule may not apply inside the wilderness or the river area. The Forest Service puts out maps, including a motor vehicle use map, and the current rules for the forest. Confirm the details with the local Forest Service office before you go.
