Montana is the fourth-largest state, but it has one of the smallest populations and few designated OHV trails. ATVers will find trails around many of the state's campgrounds but ATV use must be confined to designated trails and areas on public lands. Maps identifying "Open Areas for OHVs" are available at Bureau of Land Management (BLM) and Forest Service offices. ATVs used on public land must display registration decal. The Montana Trail Rider Vehicle Association is working with the Forest Service to develop more ATV trails. Many trails and Forest Service roads designated "Share the Road" are used by ATVs, 4x4s, dirt bikes, bicyclists and snowmobiles.
