Seminoe to Alcova is 32 miles southwest of Casper in south-central Wyoming. The byway is 64 miles long and follows CR 351 and CR 407. The gravel roads vary from single-lane to two lanes and are suitable for most vehicles. Motorhomes and vehicles pulling trailers are discouraged from traveling the portion from Semino State Park to Miracle Mile. Seminoe to Alcova is usually open May to early December.
Seminoe to Alcova Back Country Byway takes travelers across a desert landscape between the Seminoe Mountains in the west and Shirley Mountains rising in the east. Portions of the byway travel along the banks of the North Platte River, which has brought life to the Seminoe and Pathfinder Reservoirs. Byway travelers will cross the river in an area known as Miracle Mile. This stretch of the North Platte River is renowned as a blue-ribbon trout stream.
Travelers are most likely to see pronghorn antelope and mule deer grazing along the roadside. Hawks and eagles can be seen surfing the wind currents above. Elk and bighorn sheep also inhabit the area but prefer not being seen by tourists. Other wildlife preferring to keep to themselves is mountain lions, bobcats, and coyotes.
Those wishing to camp among stars in the natural surroundings will find some campgrounds maintained by the BLM. The first encountered when driving south to north is Dugway Camp-ground. There are seven sites situated on the banks of North Platte River with picnic tables and fire rings. A boat ramp provides access to the river. To the east of the byway is Pryor Flat Campground, which has five campsites with picnic tables and fire rings. A more developed campground is found in Seminoe State Park. There are nearly 100 RV and tent sites; some with hookups. The park also offers a swimming beach and boat access to the lake.
