Seminoe to Alcova Backcountry Byway

Bureau of Land Management, Wyoming.

The 64-mile Seminoe-Alcova Back Country Byway lies in south central Wyoming. As you travel, you'll pass pronghorn-grazed prairie, stark desert, and you'll climb the rugged Seminoe Mountains. Although the road is in a remote area, the amazing transformations in the landscape are worth the back-country journey.

Attractions along the byway include Alcova and Pathfinder reservoirs, Seminoe Reservoir, the Seminoe and Pedro mountains, and Seminoe State Park. With the building of Seminoe Dam and the upgrade of the road, fishermen and boaters began visiting the area.

On your trip, you might see a variety of wildlife in the area, including mule deer, antelope, bighorn sheep, golden and bald eagles, pelicans, and ferruginous hawks. You'll cross rugged mountains and the Miracle Mile, a blue-ribbon trout fishery of the North Platte River. There's a huge sand dune along the way, part of the Killpecker Sand Dunes, a dune field which reaches from western Wyoming into Nebraska.
