Missouri Breaks: Missouri Breaks National Back Country Byway Professional Review and Guide
"This spectacular but extremely rough 73-mile loop is for four-wheel-drive or high-clearance vehicles only. It bumps and scrapes through the Montana outback and its wheat fields, bluff country, and arid plains.
Stand on 1,000-foot cliffs overlooking the wild and scenic Missouri River, or hike among scrubby ponderosa pines. Special attractions: Missouri River; wildlife viewing, hiking, and mountain biking. This eTrail is a complete description of a scenic drive with a route map and information on the best travel seasons, interesting sites, recreation opportunities, camping locations, and much more."
