Bozeman Trail

Bozeman Trail

For a drive along a remote, scenic route that closely follows more than 40 miles of the original Bozeman trail, take exit 254 from Interstate 25 at Kaycee, Wyo. Follow Wyoming Highway 192 east for 19.2 miles. Turn left—north—and follow the Sussex Road, which turns to dirt after a few miles.

Follow the Sussex Road 5.0 miles to three historic-marker plaques, on the right side of the road, with more information about Cantonment Reno, an early military post near the Bozeman Trail crossing of Powder River. Continue north for about 1.5 miles. Then turn left, west, toward the Bighorn Mountains onto Nine Mile Road, also called the Bozeman Trail Road. Watch for other historical markers along the route, and bear right when you come to a fork. After 25.2 miles, the road will come to a T. Turn right here on Trabing Road, and follow it 14.7 more miles back to I-25. Total distance from the Nine Mile Road turnoff from the Sussex Road back to I-25 is 39.9 miles.

These roads are mostly well-graded, graveled county roads, best traveled in summer or early fall. For a good map, see p. 48 of Wyoming Road & Recreation Atlas. Medford, Oregon: Benchmark Maps, 2008.
