The Peter Norbeck Scenic Byway complements the park's three scenic drives and includes some of the most dramatic natural and historic features in the Black Hills. It consists of a loop made up of four numbered highways: SD 87 (Needles Highway), SD 89, SD 244, and US Route 16A (Iron Mountain Road). Sites include the Needles, Mount Rushmore, and a bird’s-eye view of the rocky peaks and forested hills of the Black Hills National Forest.
The byway is named for Peter Norbeck, a South Dakota conservationist, Governor and U.S. Senator. Norbeck planned and surveyed most of the roads located within the park and his vision inspired Custer State Park, Norbeck Wildlife Preserve and Mount Rushmore National Memorial.
Expect travel time of about two to three hours.
