Tracing old livestock trails through Wyoming, the South Big Horn/Red Wall Back Country Byway will take you into an open range still used by modern ranchers. As you drive along the gravel road, consider its pioneer history, admire the rocky Red Wall, and come away with a newfound respect for Wyoming's peaceful solitude.
In addition to sites such as the Graves Spring and Buffalo Creek Campgrounds, the Powder River, Buffalo Creek, and the Arminto/Waltman area, the byway also offers access to connecting roads leading to still more exciting places including Hell's Half Acre, the Bighorn National Forest, Edness Kimball Wilkins State Park, Seminoe to Alcova Back Country Byway, and the Oregon Trail.
Navigating the Byway:
The South Bighorn/Red Wall National Back Country Byway begins 13 miles northwest of Casper, at the junction of U.S. Highway 20/26 and Natrona County Road 125. The byway climbs the 33-Mile Stock Driveway to Buffalo Creek and the Red Wall. After retracing the steps of early settlers who moved cattle and sheep to high mountain pastures, the byway winds along the scenic Red Wall to rejoin U.S. Highway 20/26 at Waltman, Wyoming.
The route travels over Natrona County Roads 104, 105, 109, 110, and 125.
