Peter Norbeck was the governor of South Dakota in the early 1900s and was enamored with western South Dakota. It was his conservationist vision that created Custer State Forest, which was converted to Custer State Park  in 1919.
The Peter Norbeck Scenic Byway, named in his honor, winds 68 miles through the Black Hills . Segments of that byway, including the Needles Highway and Iron Mountain Road, traverse sections of Custer State Park.
The byway is not long in terms of mileage and the entire scenic route can be driven in about four hours—but the road is narrow and winding, and it is more comfortable and relaxing to drive the route in short stretches and to take time to stop and enjoy the wildlife and other scenic attributes of the drive.
