The Rattlesnake Rumble starts at the junction of Highway 29 and FS 312 south of New Augusta in the heart of the Desoto National Forest. The routes use the forest's wide gravel network including the Ragland Hills to the north and pass through the Leaf River Wildlife Management Area and the Camp Shelby training grounds; there is very little pavement and the gravel ranges from hardpacked to chunky and loose. The long distances have aid stations and drop-bag points; the time limit is twelve hours.
