Fodor's Expert Review Iron Mountain Road

Legendary former governor and U.S. senator Peter Norbeck personally oversaw the layout of this road, which was designed during the 1930s to complement the park's scenic beauty. The 17-mile route winds around several wooden, pigtail bridges and passes through three rock tunnels that frame Mount Rushmore. Plan an hour or more on this road, because the going is intentionally slow, and you'll want to stop for pictures. The road forms part of the longer Peter Norbeck Scenic Byway.
