The Seminoe-Alcova Back Country Byway is located in South Central Wyoming. The north end of the byway is in Alcova, a small settlement on WY 220 about 30 miles southwest of Casper, and the south end is in the small oil town of Sinclair, near Rawlins. Here at the junction of WY 220 and Natrona County Road 603/407, the 73-mile route passes through antelope-grazed prairie and stark desert, and climbs over the rugged Seminoe Mountains. The route has special attractions which include: the Alcova Reservior, popular for fishing and boating; Pathfinder Reservior, a favorite of windsurfers; Fremont Canyon, known for fishing, rock climbing, and popular with experienced river-runners; Seminoe Reservior, the Seminoe Mountains, the Pedro Mountains, and Seminoe State Park. The road is in a remote area, but provides amazing landscape transformations while traversing through the Seminoe Mountains, the Pedro Mountains, and Fremont Canyon, that are worth making the back-country journey to view.
