Fodor's Expert Review Needles Highway

Like Iron Mountain Road, the construction of Needles Highway was overseen by the late South Dakota politician Peter Norbeck, who took great care to complement the area's natural beauty. The winding, 14-mile road has numerous scenic overlooks, passes through two rock tunnels, and showcases the giant, fingerlike granite formations known as the Needles. The most popular stop on the route is the Needle's Eye, where one of the massive Needles formations sports a hole worn away by erosion. Because the Needle's Eye area is often packed with people and vehicles in tight quarters, use extra caution when passing through or stopping for a look.
