US Highway 85
Drive through the Badlands on US Highway 85. The area is sparsely populated and in the summer months gets extremely hot. Fill up your gas tank, check your coolant levels, and pack plenty of water for yourself. Start in Dickinson rather than Williston so the sun won't be in your eyes as well. Notable sights on this drive are: Theodore Roosevelt National Park, Little Missouri National Grasslands, Watford City and the Missouri River.
