Iron Mountain Road

Head for the hills

Experience the road that engineers once said couldn't be built. This winding road runs between Mount Rushmore National Memorial and the junction of US 16A and SD 36 in Custer State Park. Along the highway, visitors will find wildfire exhibits, pigtail bridges, magnificent Black Hills scenery, and tunnels that frame Mount Rushmore.

Constructed in 1933 under the direction of Senator Peter Norbeck, only a portion of this road lies within the park, but it is a must-see. Norbeck said of the Iron Mountain Road, "this is not meant to be a super highway, to do the scenery justice you should drive no more than 20 mph and to do it full justice you should simply get out and walk."

Where should I stay?

The historic State Game Lodge is only a couple miles from the entrance at Iron Mountain Road. 

Take it easy

Winding drives throughout the park are best when enjoyed at a slower pace. When making plans, please allow ample time to travel at a safe speed—generally 25 miles per hour or slower. Expect travel time of about 60 minutes from the State Game Lodge to Mount Rushmore.
